生物质合成气发酵生产乙醇技术的研究进展

he development of low-cost, sustainable, and renewable energy sources has been a major focus since the 1970s. Fuel-grade ethanol is one energy source that has great potential for being generated from biomass. The technology of the fermentation of biomass-generated producer gas to ethanol is discussed in this article. The advantage, process, production costs and commercialization of the technology have been analyzed. Especially, BRI Energy, Inc. and Mississippi Ethanol LLC are presented concerning the effort of fermentation of biomass-generated producer gas to ethanol. At the same time, the necessity and prospect of developing this new technology in China are proposed in this paper.
