摘　　要：从纤维素生物质原料出发,可以经水解发酵路径、气化生物合成路径和气化化学催化路径3条不同的转化路径生产纤维乙醇。通过对比各工艺路径的技术特点,结合不同工艺的技术经济指标,分别对3条技术路径进行了分析比较。分析结果表明,水解发酵路径和气化化学催化路径与气化生物合成途径相比具有一定的优势,并且随着技术的发展,气化化学催化路径将会展现出较强的竞争力。Cellulosic ethanol is regarded as one of the key alternative fuel in the future. It can be produced from cellulosic biomass through three different conversion routes. The three routes are hydrolysis fermentation pathway （HFP） ,gasification biosynthesis pathway （GBP） and gasification chemical synthesis pathway （GCP）,respectively. To evaluate the difference of the three routes, the technical characteristics and the technical-economic indicators of the routes are compared in this study. The analytical results reveal that HFP and GCP have advantages than GBP. Moreover, GCP will show stronger competitiveness with the improvement of the technology.
