本文公开了一种连续蒸汽预处理和分离玉米棒,低木质素木质纤维素生物质生产一种对酶水解敏感的浓缩纤维素固体流的工艺过程。有价值的化学品通过水解和降解半纤维素产物组成的液体和蒸气流重新回收利用。纤维素衍生的葡萄糖发酵生产生物燃料。回收的半纤维素浓缩物可以被转换为包含乙醇在内有价值的产品。
This document discloses a continuous steam pretreatment and separation of corn cob, low lignocellulosic biomass to produce a process for concentrating a cellulose solids stream that is susceptible to enzymatic hydrolysis. Valuable chemicals are re-recycled by liquid and vapor streams that hydrolyze and degrade hemicellulose products. Fermentation of cellulose-derived glucose to produce biofuels. The recovered hemicellulose concentrate can be converted into a valuable product including ethanol.
