Lignocellulosic biomass is one of the potential feedstocks to produce second-generation cellulosic ethanol and biochemicals. To enhance the enzymatic digestibility of lignocellulosic biomass for efficient enzymatic saccharification, a variety of pretreatment methods have been studied. Among these, organosolv pretreatment using ethanol is a promising pretreatment method owing to its inherent advantages, such as low solvent cost, lack of toxicity, the ability to retain most cellulose fraction in substrates for enzymatic hydrolysis, coproduction of high-purity lignin and hemicellulosic sugars, easy solvent recovery, and reuse. In this review, the research progress regarding different types of ethanol organosolv pretreatment processes has been summarized in terms of methods, substrate properties, reaction mechanisms, delignification kinetic as well as the impact of pretreatment methods on the enzymatic digestibility. Attempts are also made to provide insights into the complete utilization of lignocellulosic biomass to achieve high potential revenues. Though some ethanol organosolv processes have been studied or are being developed towards commercialization, ethanol organosolv pretreatment is still facing some challenges. Finally, the direction for future work is given to develop a proper ethanol organosolv pretreatment for commercialization.

Summary This study reports the technical and economic feasibilities of converting sugar cane residue (bagasse) into biofuel by using novel zeolite (P) catalyst. Using silica gel, aluminum powder, and sodium hydroxide as a precursor material, zeolite (P) has been successfully fabricated by template free hydrothermal synthesis. The as‐prepared catalyst is used for the conversion of sugarcane residue into valuable hydrocarbons by an autoclaving process. The effect of various parameters on catalytic and conventional (noncatalytic) pyrolysis was scrutinized and compared. It has been recognized that conventional pyrolysis (without catalyst) and catalytic pyrolysis (with Cat (I) and Cat (II)) produced 25.06%, 80.31%, and 55.26% of combustible liquid. The facial synthesis, high thermal stability, and economic and environmental feasibilities of the as‐synthesized zeolite (P) makes it a promising catalyst for biofuel production from biomass.

“…However, the conversion of wood to bio-fuel is not yet wide-spread due to technical and economic barriers. A variety of processes are used in biorefineries to convert biological materials into products including; thermochemical (pyrolysis of biomass for fuel), chemical (production of poly lactic acid), and biocatalytic methods including enzymatic biocatalysis (cellulase treatment of cellulosic biomass and whole-cell biocatalysis including fermentation) (Lasure and Zhang 2004, Tan and Xu 2010, Agnihotri et al 2015, Dziurka et al 2015.…”

The objective of this study was to investigate the effects of hot water extraction process on the dimensional stability of oriented strand composites. Aspen wood strands were extracted using various severity factor levels. Phenol formaldehyde and polymethylene diphenyl diisocyanate resins were used for production of the oriented strandboard panels. Six panel groups were produced from the extracted or unextracted aspen wood strands. The dimensional stability of the material was evaluated by measures of equilibrium moisture content and thickness swell and water absorption after soaking in water for 2 hours and 24 hours. Results obtained in this study showed that thickness swell and water absorption values significantly decreased with the hot water extraction process, with the thickness swell of phenol formaldehyde bonded panels decreasing 70% after 2 hours soaking. The panels with polymethylene diphenyl diisocyanate resin exhibited lower thickness swell and water absorption relative to the panels prepared with phenol formaldehyde resin. Equilibrium moisture content values of the panels bonded with both phenol formaldehyde and polymethylene diphenyl diisocyanate resin decreased with the extraction process. The findings of this work indicate that hot water extraction process could be effectively used to produce oriented strand composites having an enhanced dimensional stability property.
