Abstract
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.
Claims10
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.
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, a fluidizable catalyst comprising a Y-type zeolite and a stream comprising an effective amount of oxygen for combusting the fuel gas;
- and
- B) combusting the fuel gas with oxygen in the reaction zone.
