ABSTRACT:
Optimized utilization of combinations of fluid catalyst magnetic separator, classifier, and/or attriter can be used to achieve lower catalyst cost, and better catalyst activity and selectivity through control of metal-on-catalyst, particle size and particle size distribution. This process is especially useful when processing high metal-containing feedstocks. This provides a catalyst recovery unit (RCU.TM.) ancillary to an FCC or similar unit.
