本文对甜高粱茎秆原料的贮藏、汁液液态发酵、茎秆直接粉碎固态发酵以及榨汁后剩余的秆渣预处理同步糖化发酵4个方面的研究情况进行了综述,重点论述了甜高粱茎秆生产燃料乙醇的瓶颈问题即原料的贮藏和秆渣木质纤维素预处理技术。提出了一种更经济合理的甜高粱茎秆生产燃料乙醇工艺流程。
The progress of fuel ethanol production from sweet sorghum stalk is introduced in this paper, including methods of preserving raw materials, liquid-state fermentation of juice, solid-stated fermentation of smashed stalks, pretreatment of stalk bagasse and simultaneous saccharification and fermentation (SSF). The key technologies of converting sweet sorghum stalks into fuel ethanol are discussed in detail, which are raw materials preservation and pretreatment of stalk bagasse. A more economical and feasible process flow, found promising for further investigation is suggested
