Patent ID: 7431825

Claim:
A method of reducing the concentration of sulfur in gasoline produced in an FCC unit comprising: (a) adding to the FCC unit during an FCC process cycle an effective amount of one or more mixed metal oxide compounds prepared by a process comprising: (1) 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; (2) optionally heat treating the mixed metal oxide compound from step (1) at a temperature up to about 225° C. to produce a heat-treated mixed metal oxide compound in the form of an aqueous slurry; (3) drying the heat-treated compound from step (1) or step (2) 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, (4) optionally heat treating the shaped bodies from step (3) at a temperature of about 300° C. or higher to produce one or more calcined shaped bodies of a mixed metal oxide compound; and (b) reducing the sulfur content of gasoline undergoing cracking during the FCC process cycle.
