Method and equipment for production of glucose, ethanol, furfural, furane and lignin from renewable raw materials

摘要

Method and equipment for production of fermentable saccharides, ethanol, furfural, furane, lignin, acetic acid and formic acid from lignocellulosic and amylaceous materials. The method comprises one-stage or two-stage continuous thermo-compressive hydrolysis of ligno-cellulosic particles, cellulase treatment of unreacted lignocellulose, amylase treatment of formed monosaccharides combined with added amylaceous materials, and fermentation of the combined processed monosaccharide solutions into ethanol. Side products furfural, methanol, acetic acid, formic acid and lignin are recovered and purified, optionally furfural is further converted to furan. An integrated process for recovery and recycling of all products and by-products, and recycling of heat energy is disclosed.
