Abstract
A process for the production of a liquid hydrocarbon oil from a gas feed containing a lower hydrocarbon and CO , wherein the gas feed is mixed with H O to obtain a mixed gas having specific CO , H O and lower hydrocarbon contents. The mixed gas is contacted with a Rh, Ru/MgO catalyst having a specific surface area of 5 m /g or less to produce a synthesis gas with a carbon conversion efficiency Cf of at least 50%. The thus obtained synthesis gas having a H /CO molar ratio of 1.5-2.5 is reacted in the presence of a Fischer-Tropsch catalyst to obtain a liquid hydrocarbon oil, while the synthesis gas having a H /CO molar ratio of 0.5-1.5 is reacted in the presence of one or more catalysts having methanol synthesizing, dehydrating and CO shift reaction activities to obtain dimethyl ether.
