纤维素原料制取燃料酒精的研究概述

摘要

Cellulose is a renewable resource that is abundant on the earth.At present,fuel alcohol produced by pretreatment,saccharification and fermentation from cellulosic materials is more economical and environmentally friendly than gasoline or other traditional energy types.Therefore,cellulose alcohol is being developed into a new kind of renewable energy.The adoption of cellulose alcohol production technology makes the utilization of many cellulose materials from agriculture and forestry waste easy and comprehensive.It not only establishes a sustainable biological energy development model,eases the growing energy demand,but also benefits the bio-energy development,economic construction and environmental protection.This paper will present a review concerning the present technology stages of cellulose alcohol and the future development trends at home and abroad.%纤维素是地球上含量丰富的一种可再生资源,目前以其为原料经预处理、糖化、发酵等工艺得到的燃料酒精,相比汽油等传统能源,有经济、环保等优势,正在发展成为一种新型可再生能源。通过综合利用国内大量农林废弃物的纤维素原料制取燃料酒精的技术,不仅可以建立可持续生物能源发展模式,缓解日益紧张的能源需求,还可以使生物能源开发、经济建设和环境保护皆赢共益。该文以国内外纤维素制取燃料酒精的技术现状,和今后的发展方向为内容做一综述。
