Stabilizing catalytic pathways via redundancy: selective reduction of microalgae oil to alkanes. Tamura, M., Ishikawa, S., Betchaku, M., Nakagawa, Y. Soc. The form of nitrogen in biomass is significantly different from that in coal, making the conversion mechanisms of nitrogen possibly correspondingly different. In addition, the use of water-curing conditions, high Blaine value, high cement replacement ratio, and W/B tend to improve the general mechanical property performance and durability against chloride ion attack. Non-woody biomass is characterized by high levels of moisture and ash, low bulk density, low calorific value, and the presence of voidage . Horne, P. A. Within the scope of this paper, different methods were investigated and systematic suitability tests for a successful extrusion have been carried out. Biomass Bioenergy 105, 197206 (2017). 45, 584611 (2016). J. Sanyal, U., Lopez-Ruiz, J., Padmaperuma, A. The conversion of biomass and plastics through CN cleavage is still in the early stage of development, with many opportunities remaining for future research and development. In the present study, seven magnesium hydroxide and one magnesium oxide materials were used as protective coatings applied onto the surface of certain stainless steel and mild steel specimens against sulfuric acid corrosion. J. Appl. 1. As such, future research directions can be suggested with the following concept: for areas in which biomass valorization has been extensively developed, ample opportunities exist for waste plastic upcycling by adopting similar approaches, and vice versa. 2759.doc.

Chem. Papers are submitted upon individual invitation or recommendation by the scientific editors and undergo peer review Thring, R. W., Katikaneni, S. P. & Bakhshi, N. N. The production of gasoline range hydrocarbons from Alcell lignin using HZSM-5 catalyst.

Adv. J. Catal. Eng. Vollmer, I. et al. It also commonly exists in lignin and fatty acid chains. Dong, L. et al. Iannone, F. et al. Bamboo-based composites maintain the inherent excellent mechanical properties of raw bamboo whilst adding a certain degree of processing and engineering. However, during the 20th century, the increase in the application of this composite material, alongside the use of hydraulic binders, led to a disruption of traditional construction techniques. There are also substantial differences in the compositional and molecular size gaps between the two feedstocks. In the past few decades, the fossil energy crisis has drawn wide attention to produce high-quality fuels and value-added chemicals from renewable and sustainable biomass sources , .As one of the three major biomass components, lignin is the largest renewable aromatic compound resource in nature, and can be broken down to phenolic compounds Rubberised concrete exhibited less brittle failure than plain concrete, accompanied by increased lateral dilation. A clear differentiation of the fresh mortar can be made with the help of sphere penetration tests. In another study, a Pd/In2O3 catalyst was remarkably effective in breaking primary, secondary and tertiary amides while preventing hydrogenation of aromatic side chains212. Some values are expressed as averages, accounting for the various molecular weights of the polymers. Indeed, all polyether plastics contain an ether-adjacent aromatic ring in their monomer, resembling the structure of lignin. Usage of industrial by-products such as ground granulated blast furnace slag (GGBFS), gypsum, and limestone powder have gained prominence in concrete production. Hydrogen bond distinction and activation upon catalytic etherification of hydroxyl compounds. The conversion of biomass and waste plastic requires high temperatures. Polyethylene terephthalate deconstruction catalyzed by a carbon-supported single-site molybdenum-dioxo complex. & Choi, M. Single-step hydroconversion of triglycerides into biojet fuel using CO-tolerant PtRe catalyst supported on USY. Chem. However, they require co-feeding of a sulfur source (for example, H2S) because of the rapid deactivation of the metals from loss of the active metal-sulfide moieties as well as coke deposition52,53. Thus, special attention beyond bond activation should be paid to enhance the accessibility of polymer substrates to catalytic active sites. Potentiodynamic polarization and electrochemical noise technique were used to identify metastable and pitting in alkaline sulfate solutions representative of the deficient grout pore water.

The unique polyhydroxy aldose units in carbohydrates grant the possibility of the chemical production of polyols/alcohols, and other functional molecules, via retro-aldol transformation86. Trans. 4, 16401645 (2013). This study examined the resistance ability of 3 different cementitious materials: (i) epoxy, (ii) fly ash (FA) based geopolymer with various alkali to fly ash (AL/FA) ratios and (iii) Portland cement (PC) mortar under a simulated airfield circumstance. & Wang, Y. Electrochemical upgrading of depolymerized lignin: a review of model compound studies. One of the promising technologies to produce carbon textile-reinforced concrete structures is extrusion. Bamboo-based. 20, 50315057 (2018). Wastewater pipelines can be a highly corrosive environment, mainly due to the presence of biogenic sulfuric acid. Recent work by Kratish et al.187 reveals the specific roles of heterogeneous catalysts in the hydrogenolysis of polyester compounds such as PET187. 5b). Sustain. 125, 11031107 (2012). PET Monomer Recycling Special Industry Group. 142, 1426714275 (2020). & Kran, A. 51, 1758017583 (2015). Asian J. Org. Recently, catalytic systems have been developed to convert sugars into formic acids by cleaving the CC bond (Fig. Zhang, C. & Wang, F. Catalytic lignin depolymerization to aromatic chemicals. The CC bond, including CaliphCaliph and CaromC, is ubiquitous in biomass and plastics. Potentially 240EJ per year (1EJ=24Mt of oil equivalent) of energy can be delivered from wood harvesting, agriculture and municipal waste by 20601, although at present, the portion of biomass-derived energy used in industrial consumption is still small (for example, ~9% in the EU in 2017)2. Hydrogenolysis is another powerful strategy to break ester linkages (Fig. Clippel, F. et al. & Li, G. Electrochemical control of the conversion of cellulose oligosaccharides into glucose. Research into the structureactivity relationship of the metal catalysts has presented some key findings. Petcore Europe https://www.petmonomerrecycling.org/members (2019). 5) of 9Mt per year)192. Here, we show that 5 wt % cobalt supported on ZSM-5 zeolite catalyzes the solvent-free hydrogenolysis of PE and PP into propane with weight-based selectivity in the gas phase over 80 wt % after 20 h H2-free plastic conversion: converting PET back to BTX by unlocking hidden hydrogen. This highlights the high reactivity of the O-linked CaliphCaliph bond, potentially expanding the choices for the depolymerization of polyolefinic plastics. Ding, W., Liang, J. Nam, Youngeun (2022) Childcare Ideologies: A Longitudinal Qualitative Study of Working Mothers in South Korea . In another study, a yield of 91 wt% of formic acid was achieved at room temperature in the presence of H2O2 and LiOH (ref.82); the enhanced yield was attributed to the synergistic effect of the base and oxidant, leading to an improved oxidative capacity. 87, 223233 (2006). the editor(s) disclaim responsibility for any injury to people or property resulting from any ideas, As shown in Figs. 100, 186190 (2006).
