    • 1,144,499. Catalytic conversion of hydrocarbons. BRITISH PETROLEUM CO. Ltd. 18 May, 1966 [12 Jan., 1966], No. 1432/66. Heading C5E. Catalytic conversion of hydrocarbons is effected by passage over a catalyst comprising one or more elementary metals of Group VIA or VIII of the Periodic Table on a refractory inorganic oxide of an element of Group II, III or IV of the Periodic Table under conditions such that the metal remains predominantly elementary during the conversion, the catalyst having been prepared by an ion-exchange technique involving replacement of H + with Group VIA or VIII cations via alkaline cations, washing, drying and reducing. Particular hydrocarbon conversions include dealkylation; de-methanation; hydrocracking ; hydrogenation e.g. of olefins, acetylenes and aromatics; selective hydrogenation, e.g. of diolefins in the presence of mono-olefins or of mono-olefins in the presence of aromatics; and desulphurization. Examples describe the hydrogenation of isoprene ; production of methane by de-methanation or hydrocracking of n-heptane, toluene or light petroleum distillate; desulphurization of benzene; hydrogenation of benzene to cyclohexane; and dealkylation of toluene.
