    摘要： A method for the preparation of catalysts for heteroatom removal, particularly sulfur, from petroleum and synthetic fuel feedstocks. The catalyst is comprised of at least one Group VIII metal, and at least one Group VI metal, on a refractory support. The present method for preparing said catalysts comprises impregnating the Group VIII metal onto the refractory support by use of a Group VIII metal salt of an acid, and impregnating the Group VI metal onto the support by way of a Group VI heteropolyacid, wherein the acid comprising the salt of the Group VIII metal is less acidic than the heteropolyacid. The catalysts are then subjected to a heat treatment which includes a first phase wherein the catalyst is dried of free water and a second phase wherein the catalyst is heated to a temperature up to about 300.degree. C. at a heating rate from about 0.15.degree. C./min to about 15.degree. C./min.

    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.
