Beschreibung
Zusammenfassung:	A catalyst of use in hydroconversion processes comprises palladium supported on a silica-alumina carrier, which carrier has been prepared from an amorphous silica-alumina starting material having a pore volume of at least 1.0 ml/g. A process for the preparation of the aforementioned catalyst comprises preparing a carrier from an amorphous silica-alumina having a pore volume of at least 1.0 ml/g and impregnating the carrier so-formed with palladium by contacting the carrier with a palladium compound in the presence of a liquid, preferably under acidic conditions. The catalyst is of general use in hydroconversion processes, in particular the preparation of middle distillates by the hydroconversion of hydrocarbons prepared by the Fischer-Tropsch process and the hydroisomerisation of alkanes.
