The invention discloses a method for removing thiophenic sulfur from coking benzene, belonging to the field of chemical industry production of benzene. The method comprises the following steps: conveying fresh benzene to a benzene heat exchanger by a fresh benzene pump under the pressurizing action, exchanging heat, conveying to a benzene electric heater, mixing hydrogen gas with benzene steam, heating and gasifying, and conveying to a benzene desulfurization reactor; enabling the temperature to be 210-260 DEG C, the pressure to be 0.75-1.05MPa and the air velocity to be 2-3h<-1> in the benzene desulfurization reactor, adding thiophene with hydrogen to be converted into hydrogen sulfide under the action of a catalyst NHDS-8, and adsorbing onto the catalyst; enabling the benzene steam after desulfurization to enter into the benzene heat exchanger so as to convert gaseous benzene into liquid benzene; and carrying out gas-liquid separation on the liquid benzene and the hydrogen in a benzene separator, decompressing the liquid benzene through an adjusting valve, conveying to a benzene process tank, separating the hydrogen through a wire mesh demister, and conveying to a hydrogen circulator for further circulation. The method is better in thiophene removal performance, is capable of reducing the thiophene content in raw materials to be in PPb level, and is low in investment cost and simple to operate.
