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.
