Abstract: A method for producing p-xylene, comprising: a dimerization step of bringing a first raw material comprising isobutene into contact with a dimerization catalyst to generate C8 components comprising diisobutylene; a cyclization step of bringing a second raw material comprising the C8 components into contact with a dehydrogenation catalyst comprising Pt in the presence of water to obtain a reaction product comprising p-xylene; and a collection step of collecting p-xylene from the reaction product.
