Abstract: The hydrofining catalyst TORH-1, newly developed by SINOPEC Research Institute of Petroleum Processing, was put into use in a 1.0 Mt/a counter-flow continuous catalytic reforming unit in CNOOC Taizhou Petrochemical Co. Ltd. A new hydrogenation system, loaded with TORH-1 catalyst, was built before the depentanizer of continuous catalytic reforming unit to remove olefin from reformate more effectively while reducing the use of clay. The application demonstrated that under a mild operation condition (a feed throughput of 111 575 kg/h, a operating pressure of 1.7 MPa and a operating temperature of 125 °C), the olefin removal rate and aromatics loss rate could meet the quality specification by using TORH-1 after June 10,2020. The TORH-1 catalyst had excellent reaction performance.
