Patent Abstracts

Catalyst suitable for conversion reactions, such as the reforming of hydrocarbons, is prepared by intimately mixing 0.1-8% of a combined halogen with Al₂O₃, mixing therewith finely divided PtS formed by precipitation from a solution of a Pt salt in an aqueous organic solvent, and subsequently calcining the resulting Al₂O₃-combined halogen-PtS composite to form a supported catalyst containing 0.01-1% Pt. The catalyst is particularly suitable for the destructive hydrogenation or hydrocracking reactions in which hydrocarbon oils heavier than gasoline are converted to produce lower boiling products, particularly gasoline. It also may be used for hydrogenation reactions, such as the hydrogenation of unsaturated hydrocarbons, cyclic hydrocarbons, alcohols, ketones, and acids to the corresponding saturated products, or for oxidation of olefins to form olefin oxides, oxidation of alcohols, and ketones.
