Catalyst regeneration in a single stage regenerator converted to a two stage high efficiency regenerator |
摘要 |
A process and apparatus for fluidized bed catalyst regeneration. A mixture of spent catalyst, recycled hot regenerated catalyst and regeneration gas are charged to a riser having an outlet connective with a coke combustor immersed in a fluidized bed of catalyst. The coke combustor outlet is covered by the dense phase fluidized bed. Additional combustion air may be added to the fluidized bed of catalyst covering the coke combustor outlet for additional catalyst regeneration. Indirect heat exchange may heat spent catalyst in the riser and/or the coke combustor.
