PURPOSE:To produce an unsaturated hydrocarbon mixture composed mainly of ethylene and propylene selectively from synthetic gas, by using a specific catalyst prepared by heat-treating a rhodium compound supported on a carrier together with an ammonium compound. CONSTITUTION:An unsaturated hydrocarbon mixture composed mainly of ethyl ene and propylene is produced from a mixed gas containing carbon monoxide and hydrogen, by using an active rhodium catalyst having an average particle diamter of 100-200@R and prepared by supporting a rhodium compound on a carrier (preferably a porous inorganic compound having a specific surface area of 1-1,000m<2>/g, especially a silica carrier), and heat-treating the supported rhodium compound together with an ammonium compound such as ammonium chloride. The catalyst is preferably used in combination with a manganese component to improve the catalytic activity. |
