ABSTRACT:
A mixed catalyst system is disclosed which comprises particles of a first, component which requires frequent regeneration in a catalyst regeneration zone and particles of a second catalyst component which is less coke deactivated than the first catalyst component and requires less frequent regeneration than the latter, there being a sufficient difference between one or more of the characterizing physical properties of each catalyst component that the rate of circulation of particles of second catalyst component through the regeneration zone is, on the average, less than that of particles of first catalyst component.
