Abstract
The present invention relates to rare earth complex oxide combustion catalysts wherein perovskite-type rare earth complex oxide active components are carried on a support using mullite as the main phase. The present invention relates also to a process for preparing a rare earth complex oxide combustion catalyst which comprises impregnating the support with the solution of the metallic ions prepared by the ABO.sub.3 stoichiometry and then drying and calcining it. Furthermore, the present invention relates to the use of the said catalyst as a combustion catalyst for CO in the fluid catalytic cracking (FCC) process of petroleum refining.
