ABSTRACT:
Spent FCC catalyst is regenerated under net reducing conditions in a regenerator to minimize the migration of vanadium on the spent FCC catalyst particles. Reducing conditions in at least the bottom 50% of the catalyst bed are maintained by using at least two air distribution grids located in the lower 50% of the catalyst bed.
