利用海带渣制备燃料乙醇关键技术的研究
首发时间:2012-12-11
摘要:利用生物质制取燃料乙醇越来越受到重视,将组成复杂的生物质高效降解是发酵生产乙醇的关键技术。为利用海带渣制备燃料乙醇,本文从海带渣的原料组分入手,分析了利用海带渣制备燃料乙醇的可行性,并研究了海带渣的单因素水解及复合水解技术。结果表明,利用海带渣制备燃料乙醇是可行的;单独使用超高压技术并不能使海带渣多糖降解,而超高压酸解-酶解联合水解为最佳水解方案,在最优工艺条件下海带渣多糖的水解率可高达85.16%。

Research of key technology of ethanol production by using Laminaria japonica residue
Abstract:Production of bio-ethanol has been paid more and more attention. Efficient degradation of complex biomaterial is the key technology for production of ethanol. In order to utilize Laminaria japonica residue, its composition was analyzed, and several hydrolization technology were adopted in the study. The result indicated that it was not efficient by using super high pressure technology alone, while the optimal method was the acid hydrolization coupled with super high pressure followed by enzymatic hydrolization, by which the carbohydrate hydrolization ratio reached 85.16%.
Keywords: processing and storage engineering of aquatic products laminaria japonica residue ehtanol
