<p>PURPOSE:To produce a higher hydrocarbon in high selectivity, by the catalytic reaction of CO with H2 using a catalyst containing ruthenium and thorium and having decreased sensitivity to the reaction temperature which is a weak point of conventional catalyst. CONSTITUTION:A higher hydrocarbon can be produced in high selectivity, by reacting CO with H2 in the presence of a catalyst containing 0.5-10wt% of ruthenium and 1.0-86.0wt% of thorium, e.g. obtained by supporting ruthenium and thorium on a carrier, supporting ruthenium on thorium oxide or a mixture of thorium oxide and other carrier, or homogeneously mixing ruthenium with thorium oxide. The catalyst is preferably prepared by conventional process such as coprecipitation process, evaporation to dryness, immersion, deposition, etc., and heat-treated at 400-500 deg.C for 1-5hr in reducing atmosphere.</p> |
