| 摘要 |
A process of upgrading synthesis gas to hydrocarbons and oxygenated hydrocarbons, particularly olefins and carboxylic acids, comprises contacting synthesis gas with catalysts comprising the mixed oxides of ruthenium, copper, an alkali or alkaline earth metal, and optionally a metal selected from Ce, Cr, Fe, Mn, Mo, Th, Zn or mixtures thereof. The synthesis gas upgrading product may be contacted with a hydrogenation catalyst to provide alkanes, alcohols and esters, useful for fuels. Catalysts comprising the mixed oxides of ruthenium, copper, at least one alkali metal and at least one of rhodium, iridium, palladium, and platinum are further disclosed which are useful in the upgrading of synthesis gas, particularly for obtaining alkanes and alcohols. |
