论述了合成气制取乙醇的必要性,重点对以合成气为原料制取燃料乙醇的化学催化法(费托合成法)和厌氧发酵法两种技术的优缺点进行对比分析,指出了利用合成气通过厌氧发酵技术来生产乙醇具有显著的优势,同时也提出了合成气厌氧发酵制取乙醇技术中存在的问题和建议.%Ethanol production was widely concerned using ethanol as the important chemical materials or energy material. The necessity of syngas to ethanol was discussed in the assay. The advantages and disadvantages of two technologies,i. e. , Fischer Tropsch process method and anaerobic fermentation method were compared. The two technologies made ethanol production from syngas material. It was concluded that the anaerobic fermentation for ethanol production from syngas had significant advantages. Meanwhile, the problems and suggestions were put forward.
