ABSTRACT:
An isomerization process is disclosed including contacting a n-hexane hydrocarbon feed containing less than about 10 volume % naphthenic hydrocarbons with a catalyst to produce an iso-hexane containing product; wherein the catalyst is prepared by: a) incorporating tungsten on a zirconium hydroxide solid; b) drying and calcining the tungsten impregnated zirconium hydroxide; c) sizing the dried and calcined material to particle sizes between about 150 and about 600 microns; d) incorporating a Group VIII metal selected from the group consisting of nickel, platinum and palladium, and combinations thereof, on the sized material; e) drying and calcining the Group VIII metal impregnated tungsten/zirconia material; and f) contacting the second dried and calcined material with hydrogen in a reducing environment to form the catalyst which contains tungsten, zirconia and a Group VIII metal selected from the group consisting of nickel, platinum and palladium, and combinations thereof.
