The UV disinfection did not lead to significant differences in fatty acid profile and total lipid productivities, although it increased algal biomass concentration and productivity as well as lipid content. Finding uses for this glycerol will not only improve the profitability of biodiesel, it also will increase the overall carbon utilization of the process. Optimal conditions for ultrasound-assisted biodiesel production from waste tallow were fat:methanol molar ratio, 1:4; catalyst level 6% (w/w of fat); reaction time, 20 min (30 times less than conventional batch processes); ultrasonic amplitude 40% at 5 Hz. 15(2) 223-228, Zhang, X.

The research investigated that biodiesel obtained under optimum conditions from PSCO and WSCO was of good quality and could be used as a diesel fuel which considered as potential use of waste cooking oil. Biodiesel production provides a cost effective solution to economic and environmental problems through waste management. The results showed that all 14 algae strains from the genus of Chlorella, Haematococcus, Scenedesmus, Chlamydomonas, and Chloroccum were able to grow on centrate. Various solutions of KOH with different molarities (1-6 M) were used. These findings therefore highlight the potential of FTIR-ATR as an inexpensive, fast, and accurate diagnostic means for easy identification and characterization of different materials and products. PLoS One. 146744-748, Ryu, B. G.; Kim, J.; Kim, K.; Choi, Y. E.; Han, J. I.; Yang, J. W. 2013. The ZnO-Al2O3 composite support was prepared by coprecipitation method, and then loaded with ZrO2 by impregnation method to get the solid base catalyst which used for biodiesel produced through transesterification of animal fats waste oil.

Biodiesel fuel produced with the enzyme-catalyzed esterification and transesterification of high acid value waste oil through ultrasonic assistant was explored. The aim of this study was to analyze the catalytic performance of sea sand as a nonconventional catalyst in the transesterification reaction of used cooking oil and refined oil with methanol. KOH/JS could be used repeatedly five times without any activation treatment, and no significant activity loss was observed. Results from the current work show that maximum biomass productivity in indoor bench-scale cultures can reach 260 mg L-1 day(-1), compared to that of 110 mg L-1 day(-1) in outdoor pilot-scale cultures. The bioreactor was operated successfully for almost 150 h without any changes in the initial conversion yield.

Preliminary studies of two commercial and consortium of ten native strains of algae showed good growth in wastewaters. The consortium members were selected on the basis of fluorescence response after treating with Nile red reagent. The fatty acid compositions of the studied species were mainly palmitic, linoleic, alpha-linolenic, and oleic. This study is focused on the investigation of animal bones modified with potassium hydroxide (KOH) as heterogeneous solid base catalyst for transesterification of non-edible Jatropha oil. Furthermore, the iodine value (25.36 g I-2/100 g sample) and the density (0.877 g/cm(3)) of the Biodiesel met the values specified by JUS EN14214. Biodiesel produced from this plant is tested and results are comparable with international standards. Biotechnology and Bioengineering.

Vietnamese coffee biodiesel was more saturated than Columbian coffee biodiesel. M. reisseri and S. obliquus grown in the autoclaved influent showed high biomass yield (0.41 +/- 0.01 and 0.26 +/- 0.03 g dry wt. Acid formation on the selective media had previously been tested in 66 yeast strains of different genera (Candida, Pichia, Saccharomyces, Torulopsis and Yarrowia). A total of 98.29% and 97.25% fatty acids were identified in chicken and mutton fats, respectively. Thus a two-step acid catalyzed process was employed using 3.6% catalyst and 30% methanol for 5 h for the first step and 1.8% catalyst and 10% methanol for I h in the second step, resulting in a yield higher than 98% and an AV of 0.3 mg(KOH)/g(biodiesel).

The aerobic biodegradation batch tests were conducted in reactors with a working volume of 1.0 L, according to Zahn Wellens's methodology proposed by the Organization for Economic Co-operation and Development. The WCO conversion into fatty acid ethyl ester increased when the temperature was increased from 60 to 80 degrees C. When different amounts of free fatty acids were added to the reaction mixture, a slight increase on the conversion was observed. Studies on Recycling of Waste Cooking Oils for Biodiesel Production. For this reason, most policy frameworks favor its consumption. Pure biodiesel fuels, compared to the reference fuel, resulted in a slight increase in fuel consumption, in very slight differences in NOx emissions, and in sharp reductions in total hydrocarbon emissions, smoke opacity and particle emissions (both in mass and number), despite the increasing volatile organic fraction of the particulate matter.

Three types of organic wastes (sewage sludge, fruit waste and palm decanter cake from oil palm mill) were selected based on considerable generation and disposal concern in the area of study as well as lack of investigations as feed for Hermetia illucens larvae in current literatures. Owning to the presence of essential mineral nutrient content in wastewater, cultivation of microalgae using wastewater sources provides an alternative and sustainable solution for biodiesel production. The high cost of vegetable oils, which could be up to 75% of the total manufacturing cost, has led to the production costs of biodiesel becoming approximately 1.5 times higher than that for diesel [30], [44]. It was found that the microalgae was favoured to grow in domestic wastewater under the conditions of 0.02 v/v of wastewater, initial pH of 3, and 0.03 v/v of initial amount of microalgae seed with 24 h of continuous illumination. 5(68) 55252-55261, Hosseini, M.; Ju, L.

The use of a heterogeneous catalyst in the transesterification reaction of sunflower oil and waste oil for the production of methyl esters (biodiesel) has been studied. The fatty acid methyl ester (FAME) yield reached 97.3% when the transesterification was performed with a catalyst concentration of 4 wt.% at 60 degrees C for 120 min. Simultaneous water adsorption allowed the use of lower alcohol/oil molar ratios thus enabling better economics to a possible industrial process. The results showed that C zofingiensis cultivated in piggery wastewater pretreated by autoclaving and NaClO had no evident difference in the performance of nutrient removal, algal growth and biodiesel production. The best catalysts with mesoporous structure (average pore diameter 3.9-4.8 nm, pore volume 0.28-0.46 cm(3) g(-1)) and -SO3H density (0.70-0.84 mmol/g(cat)) were obtained by 4-BDS sulfonation of chemically activated DOWCs. The liquid chromatography-mass spectrometry (LC-MS) method was developed to monitor the mono-, di- and triglyceride concentrations and it was found that the method was sensitive enough to separate isomers, including diglyceride isomers. With the rising trend in crude oil prices and the limited supply of feedstock for biodiesel, WPG is anticipated to become a viable feedstock for biodiesel production in future. Journal of Engineering and Technological Sciences. The highest biodiesel Yield was obtained with 5 wt.% BMIMHSO4, methanol:oil of 15:1,60 min reaction time, at 160 degrees C, and agitation speed of 600 rpm, reduced the waste cooking oil acid value lower than 1.0 mg KOH/g. This work showed that Novozyme 435 will catalyse the esterification of FFAs and the transesterification of mono- and diglycerides typically found in UCO when Novozyme 435 is used to catalyse the pretreatement of UCO for the formation of biodiesel.
