Abstract: Provided is a method for producing p-xylene, comprising: a provision step of providing a C4 fraction comprising at least isobutene as a product formed by fluidized catalytic cracking of a heavy oil fraction; a dimerization step of bringing a first raw material comprising the isobutene into contact with a dimerization catalyst to produce a C8 component comprising a dimer of isobutene; and a cyclization step of bringing a second raw material comprising the C8 component with a dehydrogenation catalyst to produce p-xylene through a cyclization/dehydrogenation reaction of the C8 component.
