Abstract
An FCC catalyst system and a process using the catalyst system are disclosed. The catalyst system comprises a metal trap component, such as bastnaesite or barium titanate, and a sulfur oxide acceptor such as a magnesium spinel in addition to a zeolite. The metal trap and sulfur oxide components are preferably in separate particles. The catalyst formulation results in improved activity believed to result from the sulfur oxide acceptor protecting the metal trap component from the harmful effects of sulfur oxides such as the formation of stable metal oxides.
