Abstract
A process to react an oxygen containing regenerated catalyst stream prior to use in a fluidized bed reactor comprising providing a regenerated catalyst stream which comprises at least 0.001 wt % oxygen; reacting the regenerated catalyst stream with a fuel source thereby forming oxides and reducing the amount of oxygen in the regenerated catalyst stream to produce a usable regenerated catalyst stream; and injecting the usable regenerated catalyst stream into a hydrocarbon fluidized bed reactor is provided.
Claims8
A process to react an oxygen containing regenerated catalyst stream prior to use in a fluidized bed reactor comprising:
- providing a regenerated catalyst stream comprising at least 0.001wt % oxygen;
- reacting the regenerated catalyst stream with a fuel source at a temperature of from at least 400° C. and a reaction time of from 0.1 to 60 seconds thereby forming oxides and reducing the amount of oxygen in the regenerated catalyst stream to produce a usable regenerated catalyst stream;
- and
- injecting the usable regenerated catalyst stream into a hydrocarbon fluidized bed reactor.
