Abstract: A process for combusting coke from catalyst in partial burn mode is disclosed. The regenerator comprises two chambers. The bulk of the combustion is performed in a first chamber. Disengagement of the catalyst from gas is conducted in the second chamber. Heated gas with a low fraction of oxygen fluidizes catalyst in the second chamber.

Abstract: Methods for reducing flue gas particulate emissions from fluid catalytic cracking unit regenerators are provided. In one embodiment, a method for reducing flue gas particulate emissions from an FCC unit regenerator includes the steps of combining biochar with a hydrocarbon feedstock to generate a biochar-containing feedstock and contacting the biochar-containing feedstock with an FCC catalyst. In another embodiment, a method for reducing flue gas particulate emissions from a FCC unit regenerator includes the steps of fluidizing catalyst fines and biochar particles in a fluidizing gas and adhering a portion of the catalyst fines to the biochar particles while in the fluidizing gas.

Abstract: Catalyst regenerators and methods of their use are provided. A method includes combusting coke from the catalyst in a second stage regenerator to produce a second flue gas, where the second stage regenerator includes a second combustion chamber and a top having a top cross-sectional area. The coke is partially combusted from the catalyst in a first stage regenerator with a first combustion chamber having a first combustion chamber cross-sectional area greater than the top cross-sectional area. The first stage regenerator is positioned above the top of the second stage regenerator. The first combustion chamber includes a cylindrical section directly over the top and an annular section surrounding the cylindrical section. The second flue gas is vented into the first stage regenerator through a vent tube, and a portion of the second flue gas is dispersed into the annular section of the first combustion chamber.
