Abstract

A process for the manufacture of a bifunctional catalyst for the conversion of hydrocarbons, which contains a crystalline aluminosilicate of the type of the Y-zeolites as the acidic component and a noble metal as the hydrogenation component. The process constitutes a technologically simple way of manufacturing bifunctional zeolite catalysts which have at least the same activity and the same life as the catalysts manufactured by conventional methods, coupled with great heat stability and exhibit activity in the presence of H.sub.2 O, H.sub.2 S and NH.sub.3 at relatively high temperatures.
