Hydrolysis of Cellulose and Hemicellulose
Cellulosic biomass includes agricultural (e.g., corn stover and sugarcane bagasse) and forestry (e.g., sawdust, thinnings, andmill wastes) residues, portions ofmunicipal solid waste (e.g., waste paper), and herbaceous (e.g., switchgrass) and woody (e.g., poplar trees) crops. Such materials are abundant and competitive in price with petroleum, and cellulosic biomass can provide a sustainable res...
متن کاملCellulose–Hemicellulose and Cellulose–Lignin Interactions during Fast Pyrolysis
Previously, the primary product distribution resulting from fast pyrolysis of cellulose, hemicellulose, and lignin was quantified. This study extends the analysis to the examinations of interactions between cellulose−hemicellulose and cellulose−lignin, which were determined by comparing the pyrolysis products from their native mixture, physical mixture, and superposition of individual component...
متن کاملUnconventional Relationships for Hemicellulose Hydrolysis and Subsequent Cellulose Digestion
Cellulosic biomass can be pretreated with dilute sulfuric acid to recover high yields of sugars directly from hemicellulose and subsequently by enzymatic hydrolysis of the residual cellulose, and these sugars can be used to produce fuels and chemicals with unique and powerful economic, environmental, and strategic benefits. Pretreatment is costly for such biological routes, and we seek to bette...
متن کاملDiffusion of macromolecules in self-assembled cellulose/hemicellulose hydrogels.
Cellulose hydrogels are extensively applied in many biotechnological fields and are also used as models for plant cell walls. We synthesised model cellulosic hydrogels containing hemicelluloses, as a biomimetic of plant cell walls, in order to study the role of hemicelluloses on their mass transport properties. Microbial cellulose is able to self-assemble into composites when hemicelluloses, su...
متن کاملPreparation of Biodiesel and Separation of Hemicellulose from Soap Skimmings
Soap skimmings are an intermediate substrate in the production of tall oil from Kraft pulping black liquor. In this study, biodiesel was produced directly from soap skimmings before being processed into tall oil using acetyl chloride and sulfuric acid as accelerators. The effects of the accelerator amount, reaction time, and pH on the production yield were investigated. The yields of biodiesel ...
