    摘要: A novel, high porosity, high surface area catalyst is disclosed which is useful in wax isomerization processes, especially for the production of high viscosity index, low pour point lubricating oil base stocks or blending stocks. The catalyst contains a catalytically active metal component selected from the group consisting of Group VIB and Group VIII metals, and mixtures thereof, preferably Group VIII metals, and mixtures thereof, more preferably noble Group VIII metals and mixtures thereof, most preferably platinum which catalytically active metal component is present in the range of about 0.01 to 5.0 wt. %, and a fluorine content in the range of about 0.01 to about 10.0. The catalyst employs a refractory metal oxide support material, one preferably predominantly (i.e., at least 50 wt. %) alumina, most preferably completely alumina, e.g., gamma or eta alumina. The finished catalyst has a porosity, expressed in terms of pore volume, of at least about 0.50 cc/gram and a surface area such that when the porosity is multiplied by the surface area the product obtained is at least about 107, preferably at least about 110, more preferably at least about 115, most preferably at least about 120.

    摘要: A method is described for selectively dewaxing a waxy hydrocarbon oil feedstock which method comprises contacting said waxy hydrocarbon oil stock in the presence of hydrogen with a zeolite (1) which has been chemically modified by reaction, under dry, anhydrous conditions, with an organosilane wherein the zeolite has some reactive sites capable of reacting with the organosilane and where said organosilane is: (a) capable of entering into the channels of the zeolite and chemically reacting with the reactive sites present therein, as well as (b) reacting with hydroxyl groups present on the external surface of said zeolite, and (2) which has been loaded with a catalytically active hydrogenating metal component; which contacting is conducted under conditions of pressure, temperature and liquid flow velocities sufficient to effect the hydrodewaxing. Preferably the organosilane modified zeolite, either before or after the deposition of the catalytic metal component may be heated to an elevated temperature in an inert or reducing atmosphere. This heating may be conducted as an independent operation or may be conducted in situ in the catalytic dewaxing environment. In either case, the atmosphere employed is inert or reducing and is preferably hydrogen or contains hydrogen. Such deliberate or in situ heating is conducted to form a stable surface resulting from condensation-polymerization reactions.
