A method is suggested to produce liquid hydrocarbons by catalytic conversion of synthesis gas at a temperature of 204-588C and a pressure of 1-1000 atmospheres. A mixture of hafnium oxide or zirconium oxide with crystalline alumino-silicate zeolite having a silica to alumina ratio of 12-3000 is suggested as a catalyst. The catalyst activity is characterized by the ratio of the first order reaction rate constants at the cracking of n-hexane and 3-methylpentane, ranging within 1-12 at 288-510C and at a 0.1-80 wt.% hafnium oxide content or 0.1-80 wt.% zirconium oxide content. The feed synthesis gas may contain sulfur hydroxide.
