Patent ID: 7347929

Claim:
A method of reducing the concentration of sulfur in gasoline produced in an FCC unit comprising contacting a catalytic cracking feedstock with an effective amount of one or more mixed metal oxide compounds prepared by a process comprising: (a) reacting an aqueous mixture comprising at least one divalent metal compound and at least one trivalent metal compound to produce a mixed metal oxide compound in the form of an aqueous slurry; (b) optionally heat treating the mixed metal oxide compound from step (a) at a temperature up to about 225° C. to produce a heat-treated mixed metal oxide compound in the form of an aqueous slurry; (c) drying the heat-treated compound from step (b) to produce one or more shaped bodies of the mixed metal oxide compound suitable for use in the reduction of sulfur from gasoline; wherein the one or more mixed metal oxide compounds has an X-ray diffraction pattern displaying at least a reflection at a two theta peak position at about 43 degrees and about 62 degrees and (d) optionally heat treating the shaped bodies from step (c) at a temperature of about 300° C. or higher to produce one or more calcined shaped bodies of a mixed metal oxide compound.
