纤维素热解及其产物转化乙醇的研究进展

为了研究纤维素物质热解产物的乙醇转化，笔者综述了国内外近几年纤维素热解影响因素及其产物（主要为内醚糖）转化乙醇的研究现状，发现以往的研究并没有重视热解过程中各影响因素的综合作用、获得的产物，如内醚糖产率不够理想，同时对热解液主要采取水解后发酵的方式生产乙醇，也不经济可行。通过基因工程技术构建乙醇工程菌，从而实现纤维素热解液向乙醇的直接转化将成为未来发展趋势。

Progress on Pyrolysis of Cellulose and Its Conversion to Ethanol

In order to explore the conversion of cellulose biomass to ethanol, the author revlewe the current research progress on the pyrolysis conditions of cellulose and converting its pyrolysate （mainly levoglucosan） to ethanol at home and abroad in recent years. It＇ s found that previous studies are short of caring combinations with different pyrolysis conditions, which may be responsible for the yield of the product such as levoglucosan in the process of the pyrolysis, and also the conventional way via fermenting the hydrolysate of pyrolysate to ethanol is not economical. It would be a trend that the direct conversion of cellulose via pyrolysis to ethanol could be realized by constructing ethanologenic microbial strains with genetic engineering technologies in the future.
