Abstract
An improved process for the production of alkaline earth, aluminum-containing spinel compositions, preferably magnesium, aluminum-containing spinel compositions and at least one additional metal component, comprises combining alkaline earth metal, aluminum and additional metal components at selected pH conditions to form a precipitate and calcining the precipitate to form a spinel composition. The product spinel composition, 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.
