Progresses on treatment of lignocellulosic material

Progress of study on technology of pre treatment of lignocellulose is reviewed in this paper. With the exhaustion of oil and rising price of oil,studies on ethanol production from lignocellulosic material were attrative Cellulose and hemicellulose in lignocellulosic material can be converted to sugar via some suitable treatments, and then can be used in the production of ethanol by fermentation further The progresses on technology of pre treatment of lignocellulosic material were reviewed and commented, especially the hydrolysis processes via concentrated acid, two stage diluted acid, and catalysis of metal ion in diluted acid Several different pretreatment methods for cellulase hydrolysis, such as steam explosion, aminonia fiber explosion, CO 2 explosion, acid treatment and enzymatic hydrolysis method, were reviewed The advanced pre treatments of lignocellulosic material has laid a concrete basis for ethanol production at a large commercial scale
