ABSTRACT:
Sulfur oxides are removed in the regenerator zone and rapidly released as H.sub.2 S in the reactor zone of an FCC system employing a particulate SO.sub.x reducing additive comprising an alkali metal oxide. Embodiments comprise the incorporation of an inorganic support, MgO, CeO.sub.2 or Ag, and V.sub.2 O.sub.5.
