生产超低硫柴油的FHUDS-5催化剂反应性能及其工业应用

为满足炼油企业柴油质量升级的要求，中国石化抚顺石油化工研究院在成功开发改性氧化铝载体的基础上，通过优化组合活性金属组分、改进催化剂金属浸渍技术，开发出新一代FHUDS-5柴油深度加氢脱硫催化剂。中型装置试验结果表明，与FH-UDS、FHUDS-3等催化剂相比，FHUDS-5催化剂具有较高的相对脱硫、脱氮活性，达到相同脱硫深度时，反应温度降低10 ℃以上，同时具有良好的活性稳定性及原料适应性。在低压柴油加氢装置的工业应用结果表明，FHUDS-5催化剂具有优异的加氢脱硫活性，可生产满足国Ⅲ、国Ⅳ及欧Ⅴ排放标准要求的清洁柴油。

REACTIVE PERFORMANCE AND COMMERCIAL APPLICATION OF FHUDS-5 CATALYST TO PRODUCE ULTRA LOW SULFUR DIESEL

Aiming at meeting the demands of diesel quality upgrading, a new generation of FHUDS-5 catalyst for ultra deep HDS was developed by Fushun Research Institute of Petroleum and Petrochemicals based on modified alumina carrier developed newly, optimizing the combination of active metals and improving metal impregnation technology. The results of pilot plant tests showed that compared with FH-UDS, FHUDS-3 and other catalysts, FHUDS-5 catalyst possessed high relative HDS and HDN activities, to achieve the same HDS result its reactive temperature was lower more than 10 ℃. Meanwhile, FHUDS-5 catalyst demonstrated good stability and feed adaptability. The commercial application results on low pressure diesel hydrotreating units indicated that FHUDS-5 catalyst exhibited excellent HDS activity, clean diesel fuels meeting the emission standards of National Ⅲ, Ⅳ and Euro V could be produced with said catalyst.
