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.
