生物质源合成气催化转化制乙醇研究进展

Progress in Catalytic Conversion of Biomass-derived Syngas to Ethanol

生物质气化制合成气,然后再由合成气催化转化制乙醇,已引起国内外广泛的重视,因为这是改善空气质量,增加能量资源的一条新途径。介绍了合成气制乙醇反应的特点,已研究的该反应主要催化剂类型,以及它们在CO加氢反应中的表现。并分析了现有各类催化体系和反应工艺存在的主要问题,为进一步研究开发新的催化剂和反应过程提供信息。

Gasification of biomass followed by catalytic conversion of syngas to ethanol is receiving in- creased attention all over the world, because it is considered as a new route to improve air quality and to in- crease energy resource. The reaction properties of syngas to ethanol, the main types of catalysts used and their performances in CO hydrogenation were described. The problems of the present catalytic systems and reaction conditions were discussed to provide information for further research on designing new catalyst and developing new reaction process.
