Fluidized bed catalytic cracking apparatus, for hydrocarbon residue conversion, has stripper with separator, and outlets connected to catalyst and adsorbent regenerator, when catalyst particle size is larger than coked adsorbent

摘要

The respective inlets (34,32) of the riser (35) introduce regenerated catalyst and reactivated adsorbent from outlets (50,60) of catalyst and adsorbent regenerators (44,54), through by-pass valves (51,61), respectively. The outlets in bottom and intermediate locations of stripper with separator (37) are respectively connected to catalyst and adsorbent regenerators, when the particle size of catalyst is larger than coked adsorbent. An Independent claim is also included for a fluidized catalytic cracking process.
