Abstract
A catalyst regenerator for regenerating a coked catalyst produced along with a olefin by mixing naphtha and a catalyst with each other to cause a naphtha cracking reaction, and falling from a cyclone which separates the coked catalyst and the olefin produced from the naphtha cracking reaction, includes: a vessel accommodating a catalyst layer formed by stacking the catalyst; a partial oxidation burner producing a high-temperature gas containing solid carbon; and supply nozzles connected to the partial oxidation burner, installed on a bottom of the vessel toward the falling catalyst and the catalyst layer, and spraying the high-temperature gas containing the solid carbon to the catalyst and the catalyst layer.
