微藻生物质制备燃料乙醇关键技术研究进展

Research Progress on Bioethanol Production with Microalgae as Feedstocks

燃料乙醇作为一种优良的可再生液体燃料,其开发利用受到了人们的广泛关注。微藻是一种高光合、高产生物量的生物质资源,很多的藻体细胞中含有大量的淀粉、纤维素(Iα型)等多糖物质,是制备燃料乙醇的优良原料。发展利用微藻制备燃料乙醇技术工艺,对于缓解我国目前日益短缺的能源问题,减少温室气体排放和环境污染等具有很好的应用前景。综述了国内外利用微藻生物质制备燃料乙醇中所用到的关键技术、存在的问题以及今后的发展前景等。

Fuel ethanol as excellent renewable liquid fuel, has received widespread attention for its exceptional performance. Microalgae is one of the best biomass resources with high photosynthetic efficiency and high biomass yield. Microalgae rich in starch, polysaccharides, cellulose（Iot） and other substances can be used as excellent feedstock for fuel ethanol production with traditional ethanol production technology after simple treatment. Fuel ethanol production with microalgae can alleviate China＇ s growing energy problems, and reduce greenhouse gas emissions and environmental pollution. The recent research progress on microalgae ethanol reviewed and proposed its developmental potential.
