Abstract
A catalyst regeneration process is provided in which the rate of removal of carbon from the coked catalyst is increased at a relatively low temperature when the catalyst comprises a perovskite. Hydrocarbon treating processes utilizing the regenerated perovskite-containing catalysts are also provided. The regenerated catalyst is particularly suited for use in catalytic cracking of hydrocarbon residua.
