    Abstract: The formation of carbon on metals exposed to hydrocarbons in a thermal cracking process is reduced by contacting such metals with an antifoulant selected from the group consisting of tin, a combination of tin and antimony, a combination of germanium and antimony, a combination of tin and germanium and a combination of tin, antimony and germanium.

    Abstract: A highly active catalyst suitable forthe polymerization of olefins and its use are disclosed, said catalyst being prepared by(1) co-comminuting an aluminum halide; at least one electron donor; a Group IVB-VIB transition metal compound; and a support base selected from the group consisting of the Group IIA and IIIA salts and the salts of the multivalent metals of the first transition series with the exception of copper to produce a coground solid;(2) extracting said coground solid with an organic liquid; and(3) separating the solid from the liquid under such conditions that at least 5 weight percent of the aluminum in the coground solid is removed.

    Abstract: 1346856 Dehydrogenation catalysts PHILLIPS PETROLEUM CO 28 May 1971 [3 June 1970] 17958/71 Heading B1E [Also in Division C5] The activity of deactivated dehydrogenation catalyst comprising Group VIII metal selected for example from nickel, ruthenium, rhodium, palladium, osmium, iridium and platinum and, optionally, activator material, for example selected from compounds of alkali metals, alkaline earth metals, germanium, tin and lead, and/or support material, for example selected from alumina (including HF-treated alumina and flame-hydrolyzed alumina), magnesia, silica, zirconia, aluminosilicates and Group II metal aluminate spinels, is restored by a process wherein the deactivated catalyst is impregnated, optionally after oxidative burnoff to remove carbonaceous deposit, with tin or a compound thereof in an amount sufficient to provide that the reactivated catalyst contains, additional to any tin present in the deactivated catalyst, from 0.01 to 2 weight per cent of tin. The impregnated catalyst may be dried, for example at a temperature of from 100 to 400‹F, and calcined, for example at a temperature of from 800 to 1200‹F. Impregnation may be effected either by vaporization of tin or a compound thereof in the presence of the catalyst or by the use of solution; the specification discloses many suitable solvents for use in preparing such solution, water being preferred, and many suitable tin compounds which must be convertible to tin or tin oxide, must be silicon-free and preferably contain no metal other than tin and alkali metal. As exemplified, deactivated catalysts comprising platinum and tin supported on zinc aluminate spinel are immersed in aqueous stannous chloride solution and subsequently dried and, optionally, calcined at 1050‹F in air; details relating to the initial preparation of such catalysts are given in the specification. Reference also is made to impregnating with platinum a deactivated catalyst comprising platinum and tin supported on zinc aluminate spinel.
