ABSTRACT:
An improved process for the production of alkaline earth, aluminum-containing spinel compositions, preferably magnesium, aluminum-containing spinel compositions and preferably further comprising at least one additional metal component, comprises combining at least one alkaline earth metal component; at least one solid organic material acting to alter at least one property of the spinel composition and being capable of being at least partially combusted during the calcination step described hereinafter, and at least one aluminum component at selected pH conditions to form a precipitate and calcining the precipitate to form a spinel composition. The product spinel composition, prepared in the presence of a solid organic material and preferably with included additional metal components, is particularly suited for use to reduce the amount of sulfur oxides emitted from a catalyst regeneration zone, e.g., a catalytic cracking unit regeneration zone.
