A catalyst regenerator mixing naphtha and a catalyst with each other to cause a naphtha cracking reaction, separating a coked catalyst and produced olefin from each other, and regenerating the coked and falling catalyst, 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.
