ABSTRACT:
The present invention features the use of a particulate sorbent and a particulate FCC catalyst, which are physically separable, sequentially in the same FCC riser, followed by separation of commingled spent catalyst and sorbent particles from vapors, and the subsequent primary partial regeneration and heat up of spent sorbent particles and catalysts particles in an oxygen deficient burning zone, followed by physical separation of partially regenerated catalyst and sorbent particles, preferably using a cyclonic classifier to effect the separation. This is followed by secondary regeneration of the resulting segregated partially regenerated sorbent and catalyst streams in oxygen rich combustion zones to fully regenerate sorbent and catalyst particles.
