    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: Hydrogen is produced by reacting carbon monoxide with steam at a temperature of at least 200.degree. F. in the presence of a supported catalyst containing: (1) at least one alkali metal compound derived from an acid having an ionization constant below 1 .times. 10.sup.-3, (2) a metallic hydrogenation- dehydrogenation material, and (3) a halogen moiety. The ratio of metal component to alkali metal compound, each calculated on the basis of the oxide thereof, ranges from 0.0001 to about 10 parts by weight per part by weight of the alkali metal compound. The halide constituent is present in amounts in excess of about 0.01 weight %, based on total catalyst. A preferred catalyst composition comprises potassium carbonate, a mixture of cobalt and molybdenum oxides and combined chlorine contained on an alumina support.
