  • ADDITIVE-CONTAINING ANIONIC CLAYS FOR REDUCING SOX EMISSIONS FROM AN FCC REGENERATOR AND PROCESS FOR MAKING THEM
    Publication number: 20100111797
    Abstract: A process is disclosed for the preparation of an additive-containing anionic clay generally comprising the steps of: a) milling a physical mixture of a divalent metal compound and a trivalent metal compound, b) calcining the milled physical mixture at a temperature in the range of about 200 to about 8000 C, and c) rehydrating the calcined mixture in aqueous suspension to form the additive-containing anionic clay, wherein an additive is optionally present in the physical mixture of step (a) and present in the aqueous suspension of step (c), and the additive is essentially free of vanadium.
