ABSTRACT:
Disclosed are devices for introducing and uniformly distributing spent catalyst into a regenerator bed of a fluid catalytic cracking unit. Also disclosed are devices for collecting and discharging regenerated catalyst from the regenerator bed. The devices provide more uniform contacting of the spent catalyst particles with regeneration gas and consequently more efficient and complete regeneration.
