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, and a minor amount of at least one added component selected from the group consisting of alkali metal components, calcium components, barium components, strontium components, beryllium components and mixtures thereof.

A composition of matter comprising, in intimate admixture, a major amount of solid particles capable of promoting hydrocarbon conversion at hydrocarbon conditions and a minor amount of discrete entities having a composition different from said solid particles and comprising at least one magnesium-aluminum-containing spinel, and a minor amount of at least one added component selected from the group consisting of alkali metal components, calcium components, barium components, strontium components, beryllium components and mixtures thereof, said discrete entities being present in an amount sufficient to reduce the amount of sulfur oxides in an effluent flue gas.
