Recently, the FH-50A light distillate hydrogenation catalyst developed by Sinopec Dalian Research Institute was used industrially for the first time in the continuous reforming unit of Takahashi Petrochemical. This catalyst offers the advantage of high efficiency and energy savings, providing technical support for processing low-quality oils and reducing costs. The newly developed ultra-deep hydrodesulfurization catalyst FHUDS-12 by the Dalian Research Institute was used industrially for the first time at Beihai Refining & Chemical Company. Compared with that used in the previous cycle, it effectively reduced the weight of the catalyst required, providing technical support for the cost-effective and stable processing of low-quality crude oils. 1. Technical Introduction: Dalian Research Institute of Petrochemical Technology (FRIPP) is one of the key institutions in Sinopec responsible for research in refining technologies. Since the 1980s, FRIPP has been working on the development of hydroprocessing technologies for distillates; it was one of the first research institutions in China to engage in such research. Through the continuous efforts and exploration of several generations of researchers, FRIPP’s hydrorefining technologies have now reached international advanced levels, earning it a high reputation both in domestic and international markets. Against the backdrop of the transformation and development of China’s energy structure, a series of distillate hydrorefining technologies and catalysts developed by FRIPP in recent years to meet environmental requirements – including diesel hydroprocessing technology, aviation fuel hydroprocessing technology, naphtha hydroprocessing technology, and liquid-phase hydroprocessing technology platforms – have effectively promoted the production of materials such as ethylene and aromatics, thereby driving continuous progress in China’s refining technologies and chemical raw material production technologies. 2 Application Effects of FRIPP Diesel Hydrogenation Technology: The diesel hydrogenation technology developed by FRIPP enables the stable production of qualified National VI-grade vehicle diesel, even when inferior diesel fuels (such as catalytic diesel, coker diesel, and residue-added diesel) are used in blending. This technology is based on the development of highly active FHUDS series diesel hydrogenation catalysts, among which the FHUDS-5 catalyst has been recognized by international professional evaluation agencies as a top-tier catalyst. The most recently developed FHUDS-12 (Mo-Ni type, featuring low cost, low stack ratio, and high stability), FHUDS-7 (Mo-Co type), and FTX-3 (W-Mo-Ni type) have also been put into industrial use, earning a good reputation. In terms of process technology, a super-deep hydrodesulfurization technology using S-RASSG catalyst grading has been developed. This technology scientifically loads appropriate types of catalysts based on the differences in reaction conditions at various locations within the reactor, thereby enabling stable production of high-quality diesel products over extended periods of time. To date, the FRIPP diesel hydrogenation technology and catalysts have been applied in over 100 sets domestically and internationally, achieving excellent results. FRIPP’s jet fuel hydrogenation technology: The jet fuel hydrogenation technology developed by FRIPP includes conventional jet fuel hydrogenation techniques as well as liquid-phase jet fuel hydrogenation techniques. It enables the stable production of qualified 3# jet fuel under conditions of lower plant pressure levels (1.5–4.0 MPa) and high space velocities (2–6 h-1), with the use of the new FH-50 series catalysts. This technology offers great flexibility and can meet the needs for producing blended components for clean diesel. To date, the FRIPP aviation fuel hydrogenation technology and catalysts have been applied in over 60 instances both domestically and internationally, achieving excellent results. FRIPP naphtha hydrogenation technology: FRIPP has developed a series of naphtha fraction hydrogenation technologies (such as the FH-40 series and FH-50 series catalysts), including reforming pre-hydrogenation technology, reformate hydrogenation technology, and coker naphtha hydrogenation technology, which can provide enterprises with high-quality chemical raw materials. The reforming pre-hydrogenation technology can ensure that the sulfur content of the products after hydrogenation is <0.5 μg/g and the nitrogen content is <0.5 μg/g, meeting the requirements for feedstock to reforming units ； The FHDO reformate oil phase selective hydrodehydrogenation technology can selectively saturate the olefins in the reformate oil, keeping aromatic loss at <0.2%. The hydrogenation technology for coked naphtha can effectively remove olefins as well as impurities such as sulfur and nitrogen from the feedstock, meeting the requirements for the feed to ethylene plants. To date, the FRIPP reforming pre-hydrogenation technology, reformate hydrogenation technology, coker naphtha hydrogenation technology, and related catalysts have been applied in over 100 instances both domestically and internationally, achieving excellent results. The FRIPP liquid-phase hydrogenation technology platform: To further reduce the overall energy consumption and investment costs associated with hydrogenation technologies, FRIPP has developed an innovative liquid-phase hydrogenation technology platform, which has been put into industrial use for diesel hydrogenation, aviation fuel hydrogenation (including highly integrated side-stream units), hydrogenation of reformate oil, and liquid-phase hydrogenation dechlorination using ionic liquid alkylation. By eliminating the high-pressure hydrogen circulation system and avoiding the use of large amounts of excess hydrogen, this technology not only reduces both equipment investment and operating costs by over 30% but also controls the rise in reaction temperature, enabling near-isothermal operation; it thus offers significant advantages. To date, it has been applied in industrial settings more than 30 times. 3. Promotion and application in foreign markets: Thanks to its superior technical capabilities and high-quality technical services, FRIPP’s distillate oil hydrogenation technology has been exported overseas in recent years. It has been put into industrial use in numerous refineries around the world, and some companies have even won repeated contracts for this technology, resulting in extensive industrial applications. This has laid a solid foundation for further expansion of its use in the future.
