Abstract

A catalyst regeneration process with improved recovery of energy via an expander turbine-axial gas compressor set which utilizes hot regeneration gases recovered from the regeneration of fluidized catalytic cracking catalyst includes the steps of regenerating spent catalyst under conditions to combust substantially all carbon monoxide produced in the burning of carbonaceous material deposited on the spent catalyst to carbon dioxide, compressing sufficient oxygen containing gas in the axial gas compressor to prevent surging of the compressor, and introducing substantially all of the compressed gas into the regeneration zone as regeneration gas.
