In a process for converting hydrocarbons using a catalyst which is periodically regenerated to remove carbonaceous deposits, the amount of sulfur oxides exiting the catalyst regenerition zone is reduced by using a conversion catalyst comprising 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 spine, preferably an alkaline earth metal-containig spinel. The mixture of solid particles and discrete entities and a process for reducing the concentration of sulfur oxide emitted from a process of combusting sulfur-contatning material by effecting the combustion in the presence of metal-containing spinel are also disclosed. |
