ABSTRACT:
A particulate catalyst is regenerated by upward transport in a combustor having an extended length and separated from combustion gases with a single stage of cyclones. The extended length combustor ends with a termination device arranged to tangentially discharge particulate catalyst and gases into an open disengaging vessel and to achieve a high separation efficiency. Initial high separation efficiency provided by the termination device permits a single downstream stage of cyclones to reduce particulate emissions to acceptable levels. The combination of the separation device and the extended combustor can accommodate changes in particulate densities in the extended combustor without inducing cyclone overload.
