Fluid catalytic cracking system and process

摘要

One exemplary embodiment can be a fluid catalytic cracking system. The system can include a reaction zone, in turn including a reactor receiving, a fluidizing stream, a fuel gas stream, a fluidizable catalyst, a stream having an effective amount of oxygen for combusting the fuel gas stream, and a feed.

主权项

1. A process for combusting a fuel gas in a reaction zone of a fluid catalytic cracking system, comprising:
A) introducing a hydrocarbon feed, the fuel gas, and a stream comprising an effective amount of oxygen for combusting the fuel gas; and B) combusting the fuel gas with oxygen to heat a fluidizable catalyst to at least above about 650° C. in the reaction zone.
