Abstract

Compositions and processed for their use as additives for reducing the sulfur content of FCC gasoline employ a support material having deposited on its surface (a) a first metal component from Group IIB of the Periodic Table and (b) a second metal component from Group III or Group IV of the Periodic Table. The additive composition is preferably made of a montmorillonite clay support containing zinc and gallium, zinc and zirconium. Alternatively, the additive composition includes support material having deposited on its surface a metal component from Group III of the Periodic Table, preferably a montmorillonite clay support containing gallium. The clay is impregnated with the metal(s) using the known incipient wetness method and the dried powdered additive composition is preferably formed into shapes suitable for use in the FCC unit.
