Abstract
Apparatus for regeneration of spent, coke contaminated fluidized cracking catalyst by burning coke therefrom with a molecular oxygen containing regeneration gas in a fluidized dense phase bed, and for burning substantially all carbon monoxide to carbon dioxide. Means are provided for transferring heat from the top of said regeneration apparatus to the bottom, employing catalyst as the transfer medium. Additionally, means are provided for maintaining a homogeneous fluidized dense phase bed of catalyst undergoing regeneration.
