摘要: 介绍了中国石化石油化工科学研究院最新研发的TORH-1重整生成油脱烯烃催化剂在中海油气(泰州)石化有限公司1000kt/a逆流连续重整装置上的工业应用情况。为有效脱除重整生成油中的烯烃,减少下游芳烃抽提装置中改性白土、颗粒白土的使用,降低生产成本,提高经济效益,在连续重整装置的脱戊烷塔进料前新增液相选择性加氢脱烯烃装置,采用FITS脱烯烃工艺,装置处理量为111575kg/h,进氢量为280~700m3/h,操作压力为1.7 MPa,操作温度为125 °C。自2020年6月10日投用生产以来,TORH-1催化剂烯烃脱除率、芳烃损失率均满足产品质量控制要求。

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.
