Abstract
An improved process for regeneration of catalyst used in fluidized catalytic cracking of hydrocarbons using a cross-flow or swirl type catalyst regenerator is disclosed. Instead of a single catalyst withdrawal outlet for regenerated catalyst, multiple catalyst withdrawal points are provided. Use of multiple catalyst outlets, or a continuous radial catalyst outlet, greatly reduces stagnant regions in the bed. The process is useful in FCC units having inventories of from 10 to 100 tons of catalyst.
