Improving carbohydrate recovery from uncatalyzed steam pretreated hybrid poplar
The presence of SO<sub>2</sub> in steam pretreatment creates a series of problems in environmental protection, equipment corrosion, chemical catalysis and waste water treatment. Moreover, SO<sub>2</sub> increases the pretreatment severity, resulting in more sugar degradation and increased inhibitor formation. In this study, ...
Production of xylitol and ethanol from lignocellulosics
Lignocelluloses as agricultural, industrial, forest residuals, food-processing waste or paper wastes have the potential to serve as low-cost and abundant source of raw materials for the production of different biochemicals which can serve as future energy sources. These potentially valuable materials consist of sugars and ...
Improving the bioconversion yield of carbohydrates and ethanol from lignocellulosic biomass
Improving the efficiency of lignocellulosic ethanol production is of the utmost importance if cellulosic bioethanol is to be competitive with fossil fuels and first generation bioethanol from starch and sucrose. Improvements in individual processes (pretreatment, saccharification, fermentation) have been ongoing, but few ...
Techno-economic analysis of hydrocarbon biofuels from poplar biomass
Infrastructure compatible hydrocarbon biofuel that is proposed to qualify as renewable transportation fuel under the U.S. Energy Independence and Security Act of 2007 (EISA) and Renewable Fuel Standard (RFS2) is evaluated. The process uses hybrid poplar for feedstock, which undergoes dilute acid pretreatment and enzymatic ...
