ABSTRACT In a method for preparing a hydrocarbon conversion catalyst comprising a refractory inorganic oxide carrier, 0.01 to 3 weight % of a Group VIII noble metal component, a tin component and 0.1 to 3 weight % of a halogen component by the procedure of impregnating said carrier with a solution or solutions containing said metal and halogen components, the improvement which comprises a step of impregnating the said carrier with a solution comprising from about 0.01 to 2 weight % of a soluble compound of tin in a solvent comprising an acid amide selected from the group consisting of primary amides, secondary amides, tertiary amides and mixtures thereof and washing and drying the impregnated carrier. The method results in improved distribution of the tin component so that it is uniformly dispersed from the surface throughout the inner part of the catalyst. The resulting catalyst is useful in heterogeneous catalysis for the production of pollution-free fuels.
