Abstract
Hydrocarbon treating processes such as catalytic cracking and fluid coking are provided in which a perovskite-containing catalytic composition is used as catalyst. The perovskite-containing catalytic composition is produced by interrupting the reaction of perovskite precursors after formation of at least 60 wt. % perovskite and before formation of more than 99 wt. % perovskite from the precursors.
