Pretreatment method for production of bioethanol with lignocellulosic material
摘要
Abstract
Objective] With the increasing concerns on energy crisis and environmental problems , the production of bioethanol from renewable and readily available lignocellulosic biomass has received consid -erable attention around all over the world .The pretreatment methods of lignocelluloses for bioethanol pro-duction are reviewed in this paper to provide the new progress and new ideas for the production of value -added products from lignocellulosic materials .[Method] The primary pretreatment methods of lignocellu-loses from the literatures are discussed and their advantages and disadvantages are comparatively investi -gated.[Result and conclusion] Because of the complex structure , the conversion of lignocelluose into bioethanol is inefficient due to the crystalline structure of cellulose .The degraded hemicelluloses and lig-nin in the hydrolyzates produced also cause inhibition in the subsequent fermentation stage and lead to a low bioethanol yield .To obtain a high overall bioethanol yield and achieve an economically feasible pro-duction process , the destruction of cellulose crystalline structure and the removal of lignin and hemicellu-loses prior to fermentation has the potential to provide the effective bioethanol production .Therefore , many pretreatment methods are applied to destroy the crystalline structure of cellulose , improve the acces-sibility and hydrolysis efficiency of interior cellulosic macromolecules , and remove lignin and hemicellulo-ses as well as avoid the inhibitory degradation products .关键词
