Abstract: The present invention provides a method of preparing a supported catalyst, preferably a hydrocracking catalyst, the method at least comprising the steps of: a) providing a zeolite Y having a bulk silica to alumina ratio (SAR) of at least 10; b) mixing the zeolite Y provided in step a) with a base, water and a surfactant, thereby obtaining a slurry of the zeolite Y; c) reducing the water content of the slurry obtained in step b) thereby obtaining solids with reduced water content, wherein the reducing of the water content in step c) involves the addition of a binder; d) shaping the solids with reduced water content obtained in step c) thereby obtaining a shaped catalyst carrier; e) calcining the shaped catalyst carrier obtained in step d) at a temperature above 300° C. in the presence of the surfactant of step b), thereby obtaining a calcined catalyst carrier; f) impregnating the catalyst carrier calcined in step e) with a hydrogenation component thereby obtaining a supported catalyst; wherein no heat treatment at a temperature of above 500° C. takes place between the mixing of step b) and the shaping of step d).
