Many of the constituents of crude oil are paraffins. Sometimes feedstock is a synonym for biomass. That ranges from pumping it into greenhouses to boost vegetable yields to using it as a feedstock for carbon-neutral fuels. Feedstock Chemistry in the Refinery Introduction Crude oil is rarely used in its raw form but must instead be processed into its various products, generally as a means of forming products with hydrogen content different from that of the original feedstock. Then he suggested an improvement to the feedstock pump that increased the mean time between failures by a couple hours. (iv) low-boiling and high-boiling gas oils which are used to produce the various grades of fuel oil, and (v) coke, which is a solid carbonaceous product that can be used as a refinery fuel or in a gasification process to produce synthesis gas (Parkash, 2003; Gary et al., 2007; Speight, 2014; Hsu and Robinson. And the major processes by which these products are produced from crude oil constituents involve thermal decomposition. Refining processes involve the use of various thermal and catalytic processes to higher-molecular- weight constituents to lower-boiling products (Parkash, 2003; Gary et al., 2007; Speight, 2014; Hsu and Robinson, 2017; Speight, 2017). But the Tech May Not Be Very Green, Building a better chemical factoryout of microbes, Scientists Just Laid Out a Game Plan for Building a Clean Hydrogen Economy, Elon Musks $100 Million Carbon Capture Push. What is biomass as a feedstock? This broad range in molecular weights results in boiling points that range from -160C (-288F) to temperatures on the order of nearly 1,100C (2,000F). Not surprisingly, there were more studies completed in the area of physics compared to the other science disciplines because of its long history in science education research and the complex, counterintuitive, and abstract nature of its concepts. Hence, caution is advised when applying the data from model compound studies to the behavior of petroleum, especially the molecularly complex viscous feedstocks. Lubricants combine indispensable performance characteristics in transportation and industry with considerable economic value. 2022 LoveToKnow Media. Or the interference of secondary and tertiary products with the course of a reaction and, hence, with the formation of primary products may also be cause for concern. Crude oil is rarely used in its raw form but must instead be processed into its various products, generally as a means of forming products with hydrogen content different from that of the original feedstock. Feedstockmeans any controlled substance or new substance that undergoes chemical transformation in a process in which it is entirely converted from its original composition and whose emissions are insignificant, Vapor tightmeans equipment that allows no loss of vapors. Reforming processes produce streams that allow the product to be finished as the term applies to product behavior and utility. 2017; Speight, 2017, 2019, 2020). When the term feedstock is used for the feed to the entire refinery, it typically means non-crude feedstocks such as VGO and blendstocks. Agricultural crops can be roughly divided according to the composition of their (main) economic products, such as sugar, starch (grains, tubers), oilseed, protein, or fiber crop and crops for specialty products (pharmaceutics, cosmetics, dyes, fragrance, and flowers). However, the complexity of the individual reactions occurring in an extremely complex mixture and the interference of the products with those from other components of the mixture is unpredictable. For example, corn is a feedstock for ethanol production and soybean oil is a feedstock for biodiesel. Many of her labs projects focus on replacing petroleum as a feedstock. A generic process to produce PHA by bacterial fermentation involves fermentation, separation from the growth medium, and purification. Renewable feedstocks are bound to gradually replace sources of fossil origin (oil, gas and coal), both as fuel and as raw materials for the chemical industry. noun 0 0 Any bulk raw material constituting the principal input for an industrial process. chemical feedstock Definition in the dictionary English chemical feedstock Examples Stem Match all exact any words Cellulose, the world's most abundant organic polymer, can be converted into energy, fuels, materials and chemical feedstock.

Fill in the blank: I cant figure out _____ gave me this gift. Renewable feedstocks entail the elimination of non-renewable carbon resources such as coal, oil, and natural gas as feedstocks for organic chemistry, otherwise known as de-fossilization. Latex being collected from a tapped rubber tree. A refinery is a complex network of integrated unit processes for the purpose of producing a variety of products from crude oil (Chapter 4) (Parkash, 2003; Gary et ah, 2007; Speight, 2014; Hsu and Robinson, 2017; Speight, 2017). Understanding refining chemistry not only allows an explanation of the means by which products can be formed from various feedstocks but also offers a chance of process predictability. Feedstock means any controlled substance or new substance that undergoes chemical transformation in a process in which it is entirely converted from its original composition and whose emissions are insignificant; Sample 1 Sample 2 Sample 3 Based on 24 documents The term 'chemical feedstock' can also refer to intermediate byproducts that are temporarily stored for later use. It must be recognized that refining involves a wide variety of chemical reactions but the production of liquid fuels is the focus of a refinery.

In winter, gasoline will typically (in cold regions) have butane added to the mix (to facilitate cold starting), thereby changing the boiling range to 0C-220C (320F-425F). What is the definition of feedstock? Dupont is shifting from a chemical company to an advanced materials and agricultural company. The term 'chemical feedstock' can also refer to intermediate byproducts that are temporarily stored for later use. Meanwhile, another form of agricultural feedstock for heating, biogas, seems to gain little encouragement from the Report. A carbon product obtained from liquified carbon feedstock and used mainly in the rubber industry. However, understanding refining chemistry from the behavior of model compounds - even under refining conditions - is not as straightforward as it may appear. feedstocks Frequency: Raw material or fuel required for an industrial process. The inclusion of reforming processes in this category is purely for descriptive purposes rather than being representative of the chemistry involved. https://www.thefreedictionary.com/feedstock. (Industrial Relations & HR Terms) the main raw material used in the manufacture of a product. For example, in a crude oil refinery, the highest value products are transportation fuels: (i) gasoline - boiling range: 35C-220C, 95F-425F, (ii) jet fuel - boiling range 175C-290C, 350F-550F, and (iii) diesel fuel, boiling range 175C-370C, 350F-700F. By recycling materials to provide the feedstock for other products the amount of material going to incineration or landfill can be reduced. Less than one-third of a typical crude oil distills in these ranges and thus the goal of refining chemistry might be stated simply as the methods by which crude oil is converted to these fuels. Hence, caution is advised when applying the data from model compound studies to the behavior of crude oil, especially the molecu- larly complex viscous feedstocks. feedstock. A feedstock is a raw material that is used to make a useful product in an industrial process. These have few, if any, parallels in organic chemistry.

The mixture, which is a temperature-dependent feedstock separated by fractional distillation. This is very necessary when the different types of crude oil accepted by refineries are considered. Coal tar was the feedstock for all kinds of chemicals until it was replaced by oil in the 1940s. Chemical feedstocks are any raw materials used in the mass production of chemical products. Understanding refining chemistry not only allows an explanation of the means by which these products can be formed from crude oil but also offers a chance of predictability. Crude oil and the viscous feedstocks (such as heavy crude oil, extra-heavy crude oil, tar sand bitumen, and crude oil residua) contain many thousands of different compounds that vary in molecular weight from methane (CH4, molecular weight: 16) to more than 2,000 (Speight, 1994, 2014). This could be crude oil or any intermediate refining stream. However, not all possible refinery chemistry is included, and the chapter focuses on the chemistry of those processes that are applicable to viscous feedstocks such as (i) thermal processes, which involves the chemistry of thermal decomposition or cracking, (ii) catalytic processes, which involves the chemistry of thermal decomposition in the presence of or initiated by a catalyst, and (iii) hydroprocesses, which involves the chemistry of thermal decomposition in the presence of hydrogen or thermal decomposition in the presence of or initiated by a catalyst. Remembering that the word paraffin was derived from the Latin parum affinis meaning little affinity or little reactivity, it must have come as a great surprise that hydrocarbon derivatives, paraffins included can undergo a diversity of reactions thereby influencing the chemistry of refining depending upon the source of the crude oil (Smith, 1994; Laszlo, 1995; Yen, 1998). Feedstock Feedstock is any hydrocarbon input to a process unit. Cellulosic biomass [such as straw or wood] has the potential to become a significant feedstock source for [second-generation] biofuels. The Feedstock Technologies program develops science-based strategies and technologies to reduce the cost, improve the quality, and increase the quantity of sustainable, renewable, and re-usable carbon-based feedstocks. Besides the main harvested product, (Biotransformation of Waste Biomass into High Value Biochemicals). Feedstock refers to raw materials (input) fed into a process for conversion into something different (output). In 1936, the first catalytic cracking process - the Houdry process - went on stream. it means that a chemical or mixture of chemicals, fed into a. Chemical Feedstock Inventory means that feedstock and intermediate product, including rail cars, tank bottoms and linefill as applicable but less water, sediment and sludge and hydrocarbon in process units and located in interconnecting pipelines owned by Seller 's Affiliate and located at the Refinery or the Chemical Complex. Feed stock is what livestock such as cows,. This is very necessary when the different types of feedstocks crude oil accepted by refineries are considered. Feedstock definition, raw material for processing or manufacturing industry. It can be used as a feedstock in a variety of chemical and industrial processes, and presents fewer ecological concerns than traditional feedstocks like fossil fuels.

There are various theories relating to the thermal decomposition of organic molecules, and this area of crude oil technology has been the subject of study for several decades (Hurd, 1929; Fabuss et al., 1964; Fitzer et ah, 1971). The fuels are produced by thermal decomposition of a variety of hydrocarbon derivatives, high-molecular-weight paraffins included. This could be crude oil or any intermediate refining stream. Thereby lies the route to many modern products. During the 1950s, as demand for automobile and jet fuel increased, the hydrocracking process developed was applied to petroleum refining. Feedstock is an integral part of the biorefinery system. One advantage of recycled content is the avoidance of the chemical production pathway. Feedstock is any hydrocarbon input to a process unit. Is a philosophy that applies to all areas of . fermium - Fermium is the name for the element with atomic number 100 and is represented by the symbol Fm. These boiling ranges are not always precise to the degree and are subject to variation and depend upon the process used for their production. Abstract. For example, crude oil is a feedstock in a refining process which produces gasoline (petroleum). It states that a raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable. It's basic commons sense at work here. I want to receive exclusive email updates from YourDictionary. To generate a mixture of mainly aliphatic alkenes and lower molecular weight alkanes, reactant alkanes are broken apart at high temperatures, generally in the presence of a zeolite catalyst. Refined products establish the order in which the individual refining units will be introduced, and the choice from among several types of units and the size of these units is dependent upon economic factors. Or the interference of secondary and tertiary products with the course of a reaction and, hence, with the formation of primary products may also be cause for concern. Each refinery has its own range of preferred crude oil feedstock from which a desired distribution of products is obtained. Also, it must be easily available at the large scale and should have long-time storage capacity. The modern world is both built from . This is an attractive option for plastic products that are difficult to recycle mechanically due to low quality, composite nature or low economic value. n. Raw material required for an industrial process. Related terms: Biofuel; Biodiesel Production; Gasification; Biodiesel; Bio-Oil; Biochar; Biomass; Hydrogen; Pretreatment The demand for transportation fuels As the name implies, this is the discipline dealing with how gases and other chemicals and particulates in the atmosphere interact with each other, such as with the formation and destruction of ozone, both in the upper atmosphere and as a ground-dwelling pollutant. The process employs hydrogen gas to improve the hydrogen-carbon ratio in the products and to arrive at a broader range of end products. Instead, we could rely on the existing natural gas and electricity infrastructure to transport the feedstock for making clean hydrogenelectricity and methaneto smaller local hydrogen generation facilities. Definition of green chemistry. A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products. means Plant feedstock other than Ethane conforming to the specifications set forth in the Feedstock Supply Agreement. This chapter presents an introduction to refining chemistry in order for the reader to place each refinery process in the correct context of the refinery, especially when feedstock blends containing viscous feedstock components are the refinery feedstocks. They're generally unprocessed materials that are the initial basis of chemical manufacturing, such as fuel or base chemicals. American Heritage Dictionary of the English Language, Fifth Edition. stock | \ fd-stk \ Definition of feedstock : raw material supplied to a machine or processing plant Examples of feedstock in a Sentence Recent Examples on the Web Fulcrum plans to produce up to 33 million gallons of fuel per year and process up to 530,000 tons per year of prepared feedstock at the 75-acre site in Gary. This efficiency translates into a strong economic advantage, leading to widespread use of conversion processes in refineries today. noun 0 0 Raw material for industrial processing; often, specif., any of various petroleum products used in making petrochemicals and gasoline. Feedstock is also known as raw material. Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. By signing in, you agree to our Terms and Conditions Coal tar was the feedstock for all kinds of chemicals until it was replaced by oil in the 1940s. Yes! Chemical feedstocks are any raw materials used in the mass production of chemical products. These latter processes (isomerization processes) essentially change the shape of the molecule(s) and are used to improve the quality of the product (Speight, 2014). raw material for a processing or manufacturing industry. Chemistry is a difficult subject for students to learn since it involves many abstract concepts, symbols, and unfamiliar specific terms (Gilbert and Treagust 2009; Tsaparlis et al 2010). DOE Strategic Goals for the Use of Renewable Feedstocks Dramatically reduce, or even end, dependence on foreign oil (a displacement and energy component) Spur the creation of a domestic bioindustry (an enabling and economic component) Integration of chemicals with fuels will simultaneously address both goals. The first thermal cracking process - the Burton Process - came into use in 1913. What does feedstock for chemicals mean? Bio-materials may be substituted for petrochemical feedstocks as petroleum prices rise. for the petrochemical. Sample 1 Feedstock A feedstock is a type of renewable biomass that is converted into a renewable fuel. All rights reserved. Nevertheless, the chemistry of conversion process may be quite complex (King et al., 1973), and an understanding of the chemistry involved in the conversion of a crude oil to a variety of products is essential to an understanding of refinery operations. Mechanism of inhibition of bacterial growth by antibacterial compounds depends on the target bacteria. Antimicrobial agents are substance of chemical or biological or biochemical origin which inhibits the growth of microorganisms, such as bacteria, viruses, fungus, algae, or other parasites.

Renewable chemistry research has traditionally focused on finding alternatives to petrochemical-based fuels. feedstock noun [ C or U ] uk / fid.stk / us / fid.stk / material that is used to produce something in an industrial process: The plants may need massive amounts of feedstock to make relatively small amounts of fuel. In chemistry, a feedstock is a chemical used to support a large-scale chemical reaction. And even though the use of bond energy data is a method for predicting the reactivity or the stability of specific bonds under designed conditions, the reactivity of a particular bond is also subject to its environment. However, as one of the major science disciplines in elementary (Science Education Research and Practices in Taiwan). More: In the context of biofuels, a feedstock is any biomass destined for conversion to energy or biofuel. The demand for petroleum and petroleum products has shown a sharp growth in recent years (Parkash, 2003; Gary et al 2007; Speight, 201 la,b, 2014; Hsu and Robinson, 2017; Speight, 2017); this could well be the last century for petroleum refining, as we know it. The production of oxychemicals and their derivatives from renewable resources could amount . See more. As a brief introduction to the subject, in the process of thermal cracking, catalytic cracking or hydrocracking, the high-molecular-weight constituents of the feedstock decomposed to produce (i) gases, such as methane (CH,), ethane (CH3CH3), ethylene (CH,=CH,), propane (CH,CH,CH3), propylene (CH3CH=CH. They're generally unprocessed materials that are the initial basis of chemical manufacturing, such as fuel or base chemicals. The transition from mineral oil-based lubes to biodegradable lubricants from renewable raw materials is ongoing. Worldwide logistics issues are a factor, but more marginal in the supply question when the determining factor is the ability to convert feedstock to product and bolster the supply chain. Renewable raw materials may be converted by biological means to feedstocks for the chemical industry. The relative reactivity of crude oil constituents can be assessed on the basis of bond energies but the thermal stability of an organic molecule is dependent upon the bond strength of the weakest bond. ethylene glycol - via ethylene oxide hydration Good luck! A feedstock is defined as any renewable, biological material that can be used directly as a fuel, or converted to another form of fuel or energy product. But oil produces far more than just fuel. The total cost to the consumer is estimated at $ 8.4 billion a year because producing the required corn feedstock increases corn prices. Definition of biomass as a feedstock: Biomass is organic matter that comes from living organisms. This shows grade level based on the word's complexity. William Collins Sons & Co. Ltd. 1979, 1986 HarperCollins and Dictionary.com Unabridged It is therefore the purpose of this chapter to serve as an introduction to the chemistry involved in these conversion processes so that the subsequent chapters dealing with refining are easier to visualize and understand. The petrochemical manufacturing process begins with a "feedstock". The catalytic cracking process was improved in the 1940s with the use of fluidized or moving beds of powdered catalyst to produce high-octane liquids. Alkenes, or olefins, are formed by the cracking of hydrocarbons. No longer was it just a dirty industrial feedstocknow it was the fuel of the future. It must be appreciated that the stereochemistry of organic compounds is often a major factor in determining reactivity and properties. When the term feedstock is used for the feed to the entire refinery, it typically means non-crude feedstocks such as VGO and blendstocks. The trade-off among product types, quantity, and quality influences the choice of one kind of processing option over another. Nevertheless, refinery processes can be divided into three major types: The separation and finishing processes may involve distillation or even treatment with a wash solution, either to remove impurities or, in the case of distillation, to produce a material boiling over a narrower range and the chemistry of these processes can be represented by simple equations, even to the disadvantage of over-simplification of the process (Speight, 2014). The process for making fuel from biomass feedstock used in the 1800's is basically the same one used today.

This report presents an overview of the world petrochemical feedstock demand situation for natural gas, natural gas liquids (NGLs), petroleum liquid feedstocks (naphtha and gas oil), and coal. Sign up to make the most of YourDictionary. In the present context, it is necessary to recognize that (parum affinis or not) most hydrocarbon derivatives decompose thermally at temperatures above approximately 650F (340C), so the high-boiling points of many crude oil constituents cannot be measured directly and must be estimated from other measurements. feedstock noun [ C or U ] / fid.stk / / fid.stk / material that is used to produce something in an industrial process The plants may need massive amounts of feedstock to make relatively small amounts of fuel. Thus, it is not only the reactivity of the constituents of crude oil that are important in processing behavior, but it is also the stereochemistry of the constituents as they relate to one another that is also of some importance (Speight, 2014). PHAs occur naturally in a variety of organisms using various renewable waste feedstocks. The term usually refers to an organic substance. These have few, if any, parallels in organic chemistry. Use of Renewable Feedstocks is at the heart of Principle 7 of the 12 Principles of Green Chemistry. Raw material or fuel required for an industrial process. Any bulk raw material constituting the principal input for an industrial process. With salt and coal, it formed the main feedstock for the chemical industry until about 1914. The chemistry of other processes such as reforming processes, isomerization processes, alkylation processes, polymerization processes, and dewaxing processes is not included here since the chemistry of these processes falls under the general umbrella of the chemistry involved in the so-called finishing processes insofar as the processes are typically applied to the products of the initial stages of refining and prepares the various products to meet the specifications for sale. feedstock - any unprocessed material used as a supply for a manufacturing process. However, in order to understand the principles of catalytic cracking, understanding the principles of adsorption and reaction on solid surfaces is valuable (Samorjai, 1994; Masel, 1995). Contents of feedstock are sources of forms of corrosion, leading to failure of processing equipment. Smoothly step over to these common grammar mistakes that trip many people up.
