The pyrolysis gasoline hydrogenation catalysts developed by the Shanghai Research Institute have been successfully applied at Shanghai Sinopec. December 20, 2018 – Source: Sinopec News Network. According to Sinopec News Network, the SHP-02 and SHP-02/f pyrolysis gasoline hydrogenation catalysts, developed by the Shanghai Petrochemical Research Institute (hereinafter referred to as the Shanghai Research Institute), have been successfully used in the 720,000-ton/year ethylene pyrolysis gasoline hydrogenation unit at Shanghai Sinopec. The SHP-02 catalyst is a supported cobalt-molybdenum-nickel/alumina catalyst that features olefin hydrogenation activity, desulfurization and denitration capabilities, as well as good operational stability. It can be regenerated on-site, thereby fully leveraging the catalyst’s potential high performance. The Shanghai Institute worked closely with Shanghai Sinopec to complete the catalyst loading in the second-stage reactor in mid-November, and to finish the pre-sulfurization of the catalyst for that stage at the beginning of December. The process was started on the evening of December 11, proceeding smoothly and successfully on the first attempt, with the product’s bromine index meeting the requirements. At present, the unit is operating smoothly, with a reasonable temperature distribution in the bed layer, meeting the requirements for its use.
It can also be regenerated on-site, fully leveraging the catalyst’s potential high performance. What’s going on here? Isn’t in-vessel regeneration a step backward in technology?
The SHP series of hydrocracking catalysts for pyrolysis gasoline developed by the Shanghai Research Institute have been successfully put into use. According to a report from Sinopec News Network (by Hou Minbo and Shen Yan), good news came from Shanghai Petrochemical recently: the first and second stage hydrocracking catalysts of the SHP series, developed by the Shanghai Petroleum Chemical Research Institute (hereinafter referred to as the Shanghai Research Institute), were successfully used in the No. 4 hydrogenation unit of Shanghai Petrochemical’s refining department on July 14. Qualified products were produced, and the unit reached its maximum capacity shortly after operation began (110% of the design capacity); it is currently operating steadily. The catalysts originally used in Shanghai Petrochemical’s No. 4 hydrogenation unit experienced sudden fluctuations in activity at the end of May; at the beginning of June, there was a proposal to use SHP series catalysts, with delivery requested by early July. Providing technical services to large ethylene manufacturers is an undeniable responsibility of the Shanghai Institute; it also represents an opportunity for integration between research institutions and large-scale production. From its leadership to various departments, the institute has paid close attention to this task and committed significant efforts to it. The staff in the research departments and the Shanghai branch responsible for catalysts overcame challenges such as tight deadlines, heavy workloads, and unstable raw materials by formulating detailed plans and strategies. They worked together closely, leveraging the extensive experience accumulated over the years in the production of hydrogenation catalysts, to complete the catalyst production and quality control tasks on time. A total of 4.7 tons of SHP-01 first-stage hydrogenation catalyst and 6.9 tons of SHP-02/F second-stage hydrogenation catalyst were loaded this time. Before industrial application, and on the basis of thorough technical exchanges between the two parties, and taking into account the high space velocity characteristics of the device, the Shanghai Institute conducted a detailed simulated evaluation of the industrial raw materials, thereby laying a solid technical foundation for the production and use of the catalyst. On July 9, the catalysts arrived at the plant on schedule and were immediately loaded. On July 12, pre-treatment was carried out on both batches of catalysts prior to operation. Production began on the morning of July 14, and by 10 p.m., the plant was operating at full capacity. Analysis of the data showed that the product met the required standards; both batches of catalysts were able to satisfy the plant’s requirements regarding high space velocity. Their excellent performance earned recognition and positive feedback from the users. This industrial application represents the first time that the SHP series of hydrocracking gasoline first and second stage hydrogenation catalysts from Shanghai Research Institute have been operated at high space velocities simultaneously in the same facility, indicating that these catalysts for hydrocracking gasoline have entered a phase of mature deployment. The good performance compatibility of the two catalysts enables companies to offer a variety of solutions, addressing the increasingly stringent demands for cost reduction and efficiency improvement faced by businesses during periods of high oil prices.
