Method for producing ethylbenzene |
| abstract |
(57) 【Abstract】 PROBLEM TO BE SOLVED: To effectively utilize the high boiling point fraction produced as a by-product during the production of ethylbenzene to recover high value-added ethylbenzene and benzene. SOLUTION: The reaction product from the alkylation step of reacting ethylene and benzene in the presence of an alkylation catalyst and the reaction product from the transalkylation step of reacting polyethylbenzene and benzene in the presence of a transalkylation catalyst. Is sent to a separation step for separating and recovering low-boiling substances such as benzene, ethylbenzene and the polyethylbenzene content circulated in the transalkylation step, and in the method for recovering ethylbenzene as a product, a fraction having a higher boiling point than the polyethylbenzene content is obtained. Is reacted with hydrogen gas in the presence of a dealkylation catalyst to obtain a lightened reaction product, and all or most of this liquid phase portion is sent to the separation step. is there. |
