ABSTRACT:
In a fluidized cracking unit, the cracking catalyst regeneration vessel is specially adapted for high temperature operation to permit essentially complete combustion of coke on the spent catalyst particles and, in addition, the essentially complete combustion of carbon monoxide produced thereby, within the dense phase zone of the regenerator. A partition in the regenerator divides the lower dense phase zone operating at high temperatures from the upper dilute phase zone which may be cooled, for instance, by boiler tubes, water sprays and the like. The partition contains one or more rough separation catalyst knock-out means such as cyclone separators whereby hot catalyst particles are separated from the rising combusted gases and returned to the dense phase regeneration zone. In one embodiment, the regeneration vessel is elongated to facilitate recovery of most of the extra heat produced by complete carbon monoxide combustion by the catalyst particles returning to the dense phase zone. This invention is directed to both the high temperature dense phase zone catalyst regeneration process and to the apparatus employed in the process.
