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 at least one spinel, including a first metal and at least two different second metals having valences higher than the valence of the first metal, one of the second metals being aluminum and the other of the second metals being trivalent and selected from the group consisting of iron, chromium, vanadium, manganese, gallium, boron, cobalt and mixtures thereof; thereby reducing the amount of sulfur oxides exiting the catalyst regeneration zone. Improved hydrocarbon conversion catalysts are also disclosed.
