Abstract
One exemplary embodiment can be a process for fluid catalytic cracking. The process may include providing a torch oil to a stripping section of a first reaction zone, which in turn can communicate at least a partially spent catalyst to a regeneration zone for providing additional heat duty to the regeneration zone.
Claims20
A process for fluid catalytic cracking, comprising:
- A) providing a torch oil to a stripping section of a first reaction zone, which in turn communicates at least a partially spent catalyst to a regeneration zone for providing additional heat duty to the regeneration zone.
A process for fluid catalytic cracking, comprising:
- A) providing a torch oil to a stripping section of a first reactor to a combustor of a regeneration vessel to add heat duty to the regeneration vessel.
A process for fluid catalytic cracking, comprising:
- A) providing a light hydrocarbon feed to a first reactor comprising a stripping section;
- B) providing a heavy hydrocarbon feed to a second reactor;
- C) communicating a catalyst from the first and second reactors to a regeneration zone;
- and
- D) providing a torch oil to the stripping section of the first reactor to add heat duty to the regeneration zone.
