Abstract
A process for preparation of a paraffin isomerization catalyst comprising a mixture of a Group IVB metal oxide, a Group VIB metal oxide, a Group IIIA metal oxide and a Group VIII metal. The process includes the steps of: a) contacting a hydroxide of the Group IVB metal with an aqueous solution of an oxyanion of the Group VIB metal to provide a mixture, (b) drying the mixture to provide a dry powder, (c) kneading the powder with a Group IIIA hydroxide gel and a polymeric cellulose ether compound to form a paste, (d) shaping the paste to form a shaped material, (e) calcining the shaped material to form a calcined material, (f) impregnating the calcined material with an aqueous solution of a Group VIII metal salt to provide the catalyst, and (g) calcining the catalyst.
