摘要：
An improved process and apparatus are disclosed for fluidized catalytic cracking of hydrocarbons using a cross-flow or swirl type catalyst regenerator. 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.
