Abstract
Abstract An improved process for converting hydrocarbons using a catalyst which is periodically regenerated to remove carbonaceous deposits. The catalyst being comprised of a mixture containing, as a major component, solid particles capable of promoting hydrocarbon conversion at hydrocarbon conversion conditions, and, as a minor component, discrete entities comprising a major amount of alumina and, preferably, a minor, catalytically effective amount of at least one platinum group metal component disposed on the alumina, the platinum group metal component being capable of promoting the oxidation of carbon monoxide to carbon dioxide at carbon monoxide oxidizing conditions and/or promoting the oxidation of sulfur dioxide to sulfur trioxide at sulfur dioxide oxidizing conditions. Improved hydrocarbon conversion-carbon monoxide oxidation catalyst and hydrocarbon conversion-sulfur dioxide oxidation catalyst are also disclosed.
