    • An improved wax isomerization catalyst is described which is a hydrogenation metal on halogenated refractory metal oxide support catalyst characterized in that the catalyst is prepared by depositing the hydrogenation metal on the refractory metal oxide support followed by fluoriding using a low pH fluorine source such as aqueous HF. Thereafter the catalyst is crushed to expose inner surfaces, the crushed catalyst being sieved to remove fines, the catalyst charge having an average particle diameter of 1/32 inch and smaller across the longest continuous cross sectional dimension, preferably between 1/64 to 1/32". Alternatively, the catalyst is made by depositing a hydrogenation metal on a refractory metal support, crushing the material to a particle size of 1/32 inch and smaller across the longest continuous cross-sectional dimension and fluoriding said material using acidic fluorine source such as HF. Following sizing the sized catalyst is activated by heating in a hydrogen atmosphere.Isomerization using this "sized" catalyst is marked by the production of an isomerized dewaxed oil product having unexpectedly high VI and superior levels of selective conversion of wax to liquid isomerized product.

    • The present invention is directed to a process for the catalytic isomerization of waxes to liquid products, particularly to the production of high yields of liquid products boiling in the 370.degree. C..sup.+ range suitable for use as lube oil base stocks or blending stocks, said process employing as the catalyst a material made by depositing a hydrogenation metal component on a refractory metal oxide base, preferably alumina, fluoriding said metal loaded base using aqueous HF and subsequently crushing the fluorided metal loaded base to produce a sized material of 1/32 inch and less its largest cross-sectional dimension. Alternately the catalyst can be made by depositing a hydrogenation metal component on a refractory metal oxide base of 1/32 inch and less across its largest cross-sectional dimension and subsequently fluoriding said sized material using aqueous HF. In either case the catalyst is activated before being used by heating in a hydrogen atmosphere to from 350.degree. C. to 500.degree. C. for from 1 to 48 hours or more.
