Abstract
A composition for use after reductive activation as a catalyst for the conversion of synthesis gas to hydrocarbons having a carbon number greater than one, which composition has the formula: EQU Ru.sub.a A.sub.b CeO.sub.x wherein PA1 A is an alkali metal, PA1 x is a number such that the valence requirements of the other elements for oxygen is satisfied, PA1 a is greater than zero and less than 1% w/w, based on the total weight of the composition, PA1 b is in the range from zero to 10% w/w, based on the total weight of the composition, and PA1 Ce and O constitute the remainder of the composition, is produced by the process comprising the steps of: PA1 (A) bringing together in solution soluble salts of the metals ruthenium and cerium and a precipitant comprising a carbonate and/or bicarbonate and/or a hydroxide of an alkali metal or ammonium under conditions whereby there is formed a precipitate comprising ruthenium and cerium in the form of compounds thermally decomposable to their oxides, and PA1 (B) recovering the precipitate obtained in step (A). Also a process for the conversion of synthesis gas using the catalyst produced as aforsaid, optionally in combination with a zeolite.
