| 1. A process for the preparation of an alumina promoted tungstated zirconia isomerisation catalyst consisting of the following
steps:
mixing or kneading a zirconium compound, a metatungstate compound and an alumina compound;
shaping the mixture by extrusion or tabletting;
calcining the shaped material at a temperature of 600-800° C.;
impregnating the cooled calcined material with an aqueous solution of a salt of a noble metal to provide the noble metal impregnated
alumina promoted tungstated zirconia catalyst; and
calcining the noble metal impregnated alumina promoted tungstated zirconia catalyst at a temperature of 300-500° C.
