Abstract:
1. A method for producing ethanol, comprising a step of synthesizing ethanol by reacting a raw material gas in the presence of a catalyst, wherein the raw material gas is biomass gas primarily containing hydrogen, carbon monoxide, carbon dioxide, and a low hydrocarbon, obtained by a thermochemical gasification reaction of biomass, and wherein the step of synthesizing ethanol is conducted in the presence of an ethanol synthesis catalyst (1) or (2): (1) a catalyst comprising rhodium, manganese, lithium, and scandium supported on a silica carrier, or (2) a catalyst comprising rhodium, magnesium, zirconium, and lithium supported on a silica carrier; wherein ethanol is synthesized with a higher selectivity than acetic acid and acetaldehyde which are the same C2-oxygenates as the ethanol.
