1323913 Conversion catalyst UNIVERSAL OIL PRODUCTS CO 3 Sept 1970 [10 Sept 1969] 42205/70 Heading B1E [Also in Division C5] A catalyst composition comprises a platinum metal component, a germanium component and a tin component on a porous carrier. The catalyst may suitably also comprise a halogen component and a sulphur component. Specified carriers are: (a) refractory inorganic oxides, e.g. alumina, titania, zirconia, chromia, zinc oxide, magnesia, bora, thoria, silica-alumina, silica-magnesia, chromia-alumina, aluminaboria and silica-zirconia; (b) activated carbon, coke or charcoal; (c) silica or silica gel, silicon carbide, clays and silicates, e.g. attapulgite, kaolin, kieselguhr or fuller's earth; (d) ceramics, porcelain, crushed firebrick or bauxite; and (e) crystalline aluminosilicates, e.g. mordenite, and/or faujasite. The metal components are suitably present as the metal itself, oxide, sulphide, halide, oxychloride (not Pt) or aluminate (Ge only). The composition being suitably prepared by wet impregnation followed by drying and calcination. The catalyst may be reduced with hydrogen and sulphided before use. |
