纤维素生物质转化生产燃料乙醇中高浓度纤维素糖化液纳滤膜分离研究 ; Investigation of Nanofiltration Separation for High Concentration Biologic Sugar Aqueous Solution in the Process of Cellulose Bioconversion into Fuel Ethanol

Abstract

随着能源的枯竭,新能源的开发已成为社会热点。其中纤维素生物质转化生产燃料乙醇因为其原材料丰富和持续可再生而倍受重视。但其经济性特别是能耗问题是该过程工业化的关键。酶水解法纤维素生物质转化生产燃料乙醇是已实现工业化的技术路线之一,由酶水解法的特性所决定,其中各转化单元都在水溶液中进行,因此实现低能耗浓缩糖化液对酶水解法纤维素生物质转化生产燃料乙醇的经济性意义重大,而膜分离是最为合适的工艺之一。本文围绕膜分离方法浓缩糖化液过程,利用商业卷式纳滤膜组件研究了高浓度糖溶液纳滤分离过程,并进行模型构建和理论分析,为提高酶水解法纤维素生物质转化生产燃料乙醇的经济性提供技术支持,为高浓度溶质水溶液膜分离效率. ; As the energy exhausting, the discovery and development of new energy resources has become the hot topic in world wide. Cellulosic bioconversion into ethanol has been paid much attention due to the abundant amount and renewable capacity of materials. However, the economy especially energy consumption control of the process is the key and barrier for it toward industrialization.
