Abstract: An improved zeolite-containing cracking catalyst prepared by treating a zeolite-containing cracking catalyst with an aqueous solution containing a fluorine compound, drying and calcining the fluorided catalyst. In a preferred embodiment, the fluorinating solution is an aqueous solution of hydrogen fluoride. The fluorided catalyst may be used per se as a cracking catalyst, or may be physically mixed with a metallic reforming catalyst for use as a cracking catalyst. The fluorided cracking catalysts exhibit improved activity and yield higher octane products than unfluorided cracking catalysts.

Abstract: A catalytic process for the oxidation of sulfur-containing gases, e.g., sulfur dioxide and simultaneous production of sulfuric acid wherein a sulfur-containing gas is reacted with an oxygen-containing gas in the presence of a catalyst comprising an iron group metal on a solid support comprising a zeolite in a silica-alumina matrix.
