ABSTRACT:
A process and apparatus for high efficiency regeneration of spent FCC catalyst in an existing, single dense bed FCC regenerator is disclosed. Spent catalyst is added to a coke combustor immersed within the existing regenerator vessel catalyst bed. A dilute phase transport riser, above and connective with the coke combustor discharges a mixture of regenerated catalyst and flue gas. Regenerated catalyst collects around and under the coke combustor. The spent catalyst inlet, and combustion air inlet, are preferably immersed in, and in a heat exchange relationship with, the bed of hot regenerated catalyst. Heat pipes, or fins may be used to increase heat transfer into the coke combustor from the dense bed. Heating the coke combustor by indirect heat exchange, rather than recycle of hot regenerated catalyst, reduces particulates emissions and saves the energy needed to recycle catalyst in the regenerator.
