Beschreibung
Zusammenfassung:	A method for producing propylene or an aromatic hydrocarbon, wherein the production method includes a conversion reaction step in which a hydrocarbon raw material including a sulfur compound as an impurity and containing at least one C4-12 olefin is brought into contact with a zeolite-containing catalyst in a production reactor, and a catalyst regeneration step for burning off the carbonaceous substance adhered to the zeolite-containing catalyst; in the catalyst regeneration step, the temperature of the equipment and line through which the regeneration gas flows is maintained at or above the dew point temperature of the sulfuric acid contained in the regeneration gas flowing through the equipment and line.
