ABSTRACT:
A process and apparatus for regenerating fluidizable particulate cracking catalysts wherein a mixture of spent catalyst particles contaminated with carbonaceous deposits from a catalytic cracker and sufficient hot regenerated catalyst particles to bring the temperature of the mixture to the minimum temperature at which rapid oxidation of the carbonaceous deposits will be induced, are entrained in a high velocity gas stream containing sufficient oxygen to oxidize substantially all of the carbonaceous deposits on the spent catalyst particles to carbon dioxide and carbon monoxide and the resulting dilute phase catalyst particle stream is passed upwardly through a primary regeneration zone wherein the carbonaceous deposits are oxidized and the catalyst particles regenerated to a carbon content of less than 0.1%; the catalyst particles being passed to a dense phase fluidized bed of regenerated particles in a secondary regeneration zone where the combustion heat is absorbed by the particles and residual carbon monoxide is oxidized to carbon dioxide to produce flue gases containing less than 1,500 ppm carbon monoxide.
