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, preferably alkaline earth metal-containing spinel; thereby reducing the amount of sulfur oxides exiting the catalyst regeneration zone. Improved hydrocarbon conversion catalysts are also disclosed.
