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 catalytic/absorbent comprising Cu and an alkali metal oxide. Embodiments include the use of an inorganic support, such as alumina or an EC.
