SOLID SUPERACID CATALYSTS COMPRISING PLATINUM METAL AND HYDROCARBON CONVERSION PROCESSES USING SAME

摘要

A sulfated solid catalyst is provided which comprises (1) oxide or hydroxideof GroupIII or Group IV element, e.g. zirconium, and (2) a first metal comprising ametal orcombination of metals selected from the group consisting of platinum,palladium, nickel,platinum and rhenium, and platinum and tin. The catalyst may further comprise(3) a secondmetal selected from the group consisting of Group VIII elements, e.g. iron.One embodimentof the invention further comprises (4) a third metal selected from the groupconsisting ofGroup V, VI and VII elements, e.g. manganese. The catalyst of the invention isuseful forthe isomerization of normal alkanes having 4 to 40 carbon atoms per molecule,for thenaphtha upgrading of a hydrocarbon feedstock and for the hydrocracking of ahydrocarbonfeedstock.
