ABSTRACT OF THE DISCLOSURE SYNGAS CONVERSION CATALYST PRODUCTION AND USE THEREOF 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: RUaAbCeOx wherein A is an alkali metal, X is a number such that the valence requirements of the other elements for oxygen is satisfied, a is greater than zero and less than 1% w/w, based on the total weight of the composition, b is in the range from zero to 10% w/w, based on the total weight of the composition, and Ce and O constitute the remainder of the composition, is produced by the process comprising the steps of: (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 (B) recovering the precipitate obtained in step (A). Also a process for the conversion of synthesis gas using the catalyst produced as aforesaid, optionally in combination with a zeolite.
