  • Process for removing sulfur oxides with an absorbent which contain an anionic clay
    Patent number: 4952382
    Abstract: Disclosed are hydrocarbon conversion catalyst compositions, such as fluidizable cracking catalyst compositions, containing an anionic clay, e.g. a clay having a hydrotalcite, and 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.
    Type: Grant
    Filed: May 19, 1989
    Date of Patent: August 28, 1990
    Assignee: Akzo N.V.
