Abstract
An FCC process mixes spent and regenerated catalyst to obtain thermal equilibrium of a blended catalyst stream before contacting feed with the blended catalyst stream. The spent and regenerated catalyst from the reactor and regenerator catalyst may be mixed in a blending vessel located at the bottom of an FCC riser that can also serve as a hot catalyst stripper.
