Abstract
Disclosed are hydrocarbon conversion catalyst compositions, such as fluidizable cracking catalyst compositions, containing an anionic clay, e.g. a clay having a hydrotalcite, an ettringite or a hydrocalumite structure, for the conversion of sulphur-containing feedstocks, the anionic clay serving as sulphur oxides binding material. Also disclosed are absorbents containing the anionic clay embedded in a matrix. The absorbents may be used to purify sulphur oxides-containing gases.
