Abstract
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.

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, comprising:
- 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.
A catalyst regenerating method of regenerating a coked catalyst in a process of producing olefin from naphtha using a catalyst cracking system, comprising:
- a first step of supplying a high-temperature gas containing solid carbon to a catalyst layer;
- and
- a second step of coking a catalyst of the catalyst layer by the high-temperature gas and then burning the solid carbon coked on the catalyst to regenerate the catalyst.
