摘要： Natural gas is steam reformed to a mixture of carbon monoxide, carbon dioxide and hydrogen which mixture is converted, over a methanol synthesis catalyst, to a mixture of methanol, carbon oxides and hydrogen which methanol is converted to C.sub.5.sup.+ hydrocarbon gasoline, light gas and water, the water is separated out and may be recycled as steam, the portion of the hydrocarbon fraction which comprises light olefins and isobutane is subjected to acid alkylation to product very high octane hydrocarbon gasoline which is admixed with the C.sub.5.sup.+ hydrocarbon gasoline from the methanol conversion. The light fuel gas (C.sub.1 to C.sub.2) produced in the methanol conversion is recycled to the steam reformer and the LPG (C.sub.3 + C.sub.4) produced therein is recovered and sold.
