Hydrofining catalyst

The hydrogenation catalysts used in China are mainly from the Fushun Research Institute, namely the FZC-series, FC-series, and FF-series; the “F” at the beginning represents the Fushun Research Institute. There are also hydrogenation catalysts in series that start with 3, such as 3936, which are mainly catalysts produced by Fushun Petroleum Plant No. 3. Then there’s the R-series, which of course belongs to the Institute of Rock Mechanics. These are the main series. This post was last edited by zxh6267 on 2009-4-6 08:10]

Based on the active metal used, hydrocracking catalysts for oils generally include Co-Mo series, Ni-Mo series, W-Ni series, Co-Mo-Ni series, Co-Mo-Ni-W series, etc.; in addition, there are also precious metal-based series such as Pt series and Pb series.

Foreign refined catalysts are relatively simple: Co-Mo/Al2O3, Ni-Mo/Al2O3; modified versions using elements such as P also exist. There are more variations in domestic catalysts. Among those currently in use, only Ni-W is a 2-metal catalyst, while the others are 3- or 4-metal catalysts, with combinations such as Co-Ni-Mo, Co-Mo-Ni-W, etc. 　 The precious metals mentioned upstairs should be considered as modified catalysts; their main functions are to saturate aromatic compounds, reduce density, increase the octane number, and lower the 95% distillation temperature, among other things.

The main ones abroad include UOP’s Co-Mo-type hydrodesulfurization catalysts N-40, N-108, and N-200； NiMo-type deep aromatic saturation hydrogenation catalysts HC-H, HC-K, HC-P, HC-R, and HC-T ； Deeply saturated catalyst for precious metals AS-250 ； The newly developed CoMo-type diesel deep desulfurization catalysts HR-416 and HR-426 from IFP. If the goal is to improve the stability of diesel fuels, increase their cetane number, or reduce the aromatic content, the newly developed NiMo-type ultra-deep desulfurization/denitration catalyst HR-488 can be used. The Danish company Topsφe has developed a series of TK catalysts, including TK-554 (a catalyst for deep desulfurization of diesel), TK-573 (a catalyst for deep desulfurization of diesel), TK-574 (an ultra-deep desulfurization catalyst for diesel), TK-907 (a catalyst for aromatic saturation and cetane number improvement), and TK-908 (another catalyst for aromatic saturation and cetane number improvement). The American company United Catalysts has developed the ASAT catalyst, which possesses the functions of desulfurization, denitration, and aromatization removal. Engelhard DeMeern and Raytheon have jointly developed the REDAR catalyst along with the corresponding processing technology (AM-00-22) for producing low-sulfur, low-aromatic diesel fuels. The REDAR catalyst uses Pt-Pd as the hydrogenation active components and amorphous silica-alumina spheres as the carrier; it possesses strong resistance to nitrogen poisoning, and can still maintain excellent hydrodearomatization activity even when the feed sulfur content is as high as 250 μg•g-1 and the nitrogen content is as high as 100 μg•g-1

Hydrofining catalysts – Catalyst types: RT hydrocracking catalyst series: RT-1, RT-5; CR series: CR-2, CR-3, CR-4; RN hydrofining and cracking catalyst series: RN-1, RN-2, RN-10; RS hydrodesulfurization and cracking catalyst series: RS-1, RS-200; RAs hydrodesulfurization and dearsenification catalyst series: RAs-3, RAs-4; Protectants series: RG-1; Lubricant hydrogenation catalyst series: RJW-1, RJW-2; Special catalysts: RP-1, RL-1, RDD, RDW-1; Other products: CH-6, CH-19, FCT-1

Thank you to everyone above; so what are the temperature and pressure for diesel hydrogenation in industry?
