    摘要: PROBLEM TO BE SOLVED: To provide a method for synthesizing ethanol by which the ethanol can be synthesized by using a hardly fermentable raw material such as wood pitch, coal, natural gas, petroleum residue, heavy oil, biomass or the like as a raw material to enlarge the range of the raw material for producing the ethanol, and to provide an apparatus therefor. SOLUTION: The method for synthesizing the ethanol includes a methyl acetate-synthesizing step of synthesizing a methyl acetate-containing gas containing the methyl acetate (CH 3 COOCH 3 ) by the carbonylation reaction of dimethyl ether (CH 3 OCH 3 ), an ethanol-containing gas-synthesizing step of synthesizing an ethanol-containing gas containing the ethanol (C 2 H 5 OH) by the hydrogenation reaction of the methyl acetate, and an ethanol-separating step of separating the ethanol from the ethanol-containing gas.
