ABSTRACT OF THE DISCLOSURE A composition for use after reductive activation as a catalyst in the conversion of synthesis gas to hydrocarbons, the composition having the formula: RUaAbCeOx (I) 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 5% 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 steps of: (A) adding a solution or solutions of soluble compounds of the metals ruthenium an cerium, and optionally also an alkali metal compound, to a solution of a precipitant comprising a carbonate and/or a bicarbonate and/or a hydroxide of an alkali metal or ammonium under conditions whereby there is formed a precipitate comprising ruthenium and cerium, and optionally. also an alkali metal, in the form of compounds thermally decomposable to the metals and/or their oxides, and (B) recovering the precipitate obtained in step (A).
