A method is described of converting a major fraction of carbon monoxide within a gas mixture including hydrogen and carbon monoxide to produce an aliphatic hydrocarbon product with less than 10% by weight aromatics, the product having a major proportion of weight of C/sub 5/ and higher hydrocarbons in the gasoline boiling point range with a research octane rating of more than 80 comprising; forming a catalyst consisting essentially of a mixture of cobalt, thoria and crystalline zeolite having a silica to alumina ratio of about 25-50 and a pore size of 5 to 6 angstroms wherein cobalt is included at 6-20%, thoria is included at 0.5-3% and crystalline zeolite is included at 75-93% by weight; and contacting the catalyst with the gas mixture including hydrogen and carbon monoxide at a temperature essentially of 280/sup 0/C at 20-30 atmospheres pressure whereby the aliphatic hydrocarbon is formed. A catalyst for the conversion of a major fraction of hydrogen and carbon monoxide gases is described at a temperature essentially of 280/sup 0/C at 20-30 atmospheres pressure to a liquid aliphatic hydrocarbon product with less than 10% by weight aromatics, the product having a major proportion by weight of C/sub 5/ and higher hydrocarbons in the gasoline boiling range with a research octane rating of more than 80.
