摘要: 介绍了2.0?Mt/a柴油加氢精制装置催化剂的卸剂、再生、开工及标定情况,同时也提出了装置在卸剂、再生及开工过程中出现的问题及解决办法,为同类装置提供参考。该装置的开工运行标定结果表明,再生催化剂活性基本恢复到与新鲜剂的水平。直馏柴油与催化裂化柴油的混合油经过加氢精制后脱硫率为98.5%,产品柴油的硫质量分数为170?μg/g。

Abstract: The unloading and ex-situ regeneration of catalyst, and restarting for 2.0 Mt/a diesel hydrotreating unit and problems occurred during these stages were introduced. The solutions for solving above problems were suggested. The calibration results indicate that the activity of the regenerated catalysts recovers well, close to the fresh catalyst. The hydrodesulfurization rate reaches 98.5%, and the sulfur content in diesel product is 170 μg/g, when a mixed feedstock of straight-run diesel and FCC diesel is processed.

Key words: diesel hydrotreating, catalyst, regeneration, startup
