Summary: Efforts to improve lignocellulosic pretreatments have been costly in second-generation ethanol production, but high-concentration PEG shows promise in increasing ethanol production without the need for additional chemical or physicochemical pretreatments. Operational conditions in a study using high PEG concentrations and green coconut fiber as substrates showed increased ethanol production, with the addition of salts, yeast extract, or peptone further enhancing ethanol yield.

Summary: The NaOH catalytic ethanol pretreatment of sugarcane bagasse improved glucose yield by assisting delignification and preserving cellulose and hemicellulose. Higher temperature and longer time resulted in higher glucose yield, while the addition of Tween 80 significantly reduced enzyme usage and enzymolysis time while maintaining comparable glucose yield. This study provided an economically feasible method for generating glucose followed by fermentation and conversion to platform chemicals.

Summary: This study explored the pyrolysis behaviors and mechanisms of different monosaccharides, including arabinose, galactose, galacturonic acid, and glucuronic acid. The roles of structural differences in these monosaccharides were analyzed, and it was found that glucuronic acid undergoes a special C-C bond breaking reaction during pyrolysis. The findings provide a deep understanding of the pyrolysis chemistry of hemicellulose and the role of different branches.

This study presents a detailed quadrature-based method of moments (QMOM) soot model coupled with a state-of-the-art flow solver for the simulation of gasoline engines. The model accurately describes the entire cause-and-effect chain of soot formation, growth and oxidation. Experimental validation and engine cycle simulations are used to identify the root cause of observed soot formation hotspots.
