摘要 大连石化分公司400万t/a柴油加氢装置采用Shell Global Solution工艺技术。为使产品满足国V排放标准,反应器于2017年停检期间更换Axens公司生产的Impulse^(TM) HR1246催化剂及ACT069、ACT077、ACT935、ACT955保护剂。通过对原料性质、反应温度与加权平均温度、主要操作条件等相关数据进行评估,Impulse^(TM) HR1246催化剂在加氢脱硫、加氢脱氮以及提高十六烷值等方面均表现较好的加氢活性。装置反应温度与加权平均温度长时间趋于稳定,表明Impulse^(TM) HR1246催化剂具有较好的稳定性。此外,大连石化公司采用降低装置加工负荷、产品部分转循环、降低原料硫含量等方面的举措,为催化剂长周期运行创造了较好的运行条件。 Shell Global Solution technology is used in the 4 Mt/a diesel hydrogenation unit of Dalian petrochemical company. During overhaul in 2017, Impulse^(TM) HR1246 catalyst and ACT069, ACT077, ACT935 and ACT955 protectants produced by Axens company were used in order to upgrade diesel quality for meeting the national V emission standards. Impulse^(TM) HR1246 catalyst showed good hydrogenation activity in hydrodesulfurization, hydrodenitrogenation and improving cetane value through assessing related data of the properties of raw materials, reaction temperature and weighted average temperature, and the main operating conditions. The reaction temperature and the weighted average temperature of the device tended to be stable for a long time, indicating that the Impulse^(TM)HR1246 catalyst had good stability. In addition, Dalian petrochemical company created better operation conditions for the catalyst long term operation by taking measures,such as reducing device load, partial circulation of products and reducing sulfur content of raw materials.
