Conteúdo: |
In the present dying age of petroleum , efforts are undertaken to develop technologically advantageous processes for the production of ethanol from biomass residues, such as agricultural wastes. Dilute acid hydrolysis of agricultural wastes, in order to get reducing sugars fermentable to ethanol, appers to be commercially more attractive in comparison to the enzymatic hydrolysis process. At present, bagasse and rice husk have been hydrolysed by using 1% acetic acid (process derived) and 10% Ca3 (PO4)2, respectively, at 205o, to get in the farmer step, xylose. In the latter one, the spent biomass residues were hydrolysed by using 1% H2SO4, to get glucose. The use of Ca3 (PO4)2 in the first step led to greater yields of xylose, incomparison to those obtained with acetic acid catalysed hydrolysis. The lignin left behind can be hydrocracked to get phenols and hydrocarbons. Thus, this new two-step hydrolysis process affords the convenient production of xylose and glucose in separate steps. Both the xylose and glucose streams can be fermented to get ethanol (a source of fuel and chemical feedstocks). |
