Patent number: 9233892Abstract: A method for producing monocyclic aromatic hydrocarbons includes a step of introducing a feedstock oil into a cracking/reforming reactor, bringing the feedstock oil into contact with a catalyst, and causing the feedstock oil to react, a step of purifying and recovering the monocyclic aromatic hydrocarbons separated from the product produced in the reaction step, a step of hydrogenating a heavy fraction separated from the product, and a recycling step of returning a hydrogenation reactant of the heavy fraction to the cracking/reforming reaction step. In the recycling step, the hydrogenation reactant is introduced at a location different from an introduction location of the feedstock oil into the reactor so that a time during which the hydrogenation reactant is in contact with the catalyst in the reactor becomes shorter than a time during which the feedstock oil is in contact with the catalyst in the reactor.Type: GrantFiled: March 23, 2012Date of Patent: January 12, 2016Assignees: JX Nippon Oil & Energy Corporation, CHIYODA CORPORATIONInventors: Shinichiro Yanagawa, Masahide Kobayashi, Ryoji Ida, Susumu Yasui, Yoshishige Sugi, Atsushi Fukui, Atsuro Nagumo
