摘要
中国石化集团洛阳石化工程公司针对催化裂化汽油的特点开发出催化裂化汽油加氢脱硫及芳构化技术(简称Hydro-GAP),该技术采用具有芳构化功能的催化剂,在催化裂化汽油加氢脱硫的过程中,不降低汽油的辛烷值。实验结果表明,催化裂化汽油脱硫率平均为85％左右,研究法辛烷值提高0．2～0．6个单位,马达法辛烷值提高1．3～1．8个单位,抗爆指数提高1个单位左右,C5+总液收大于95％。失活催化剂烧焦再生后,其活性可基本恢复到新鲜催化剂的水平。 Hydro-GAP催化剂7 800 h活性稳定性及再生剂3 200 h性能评价试验结果表明,催化剂的稳定性和再生性能良好。
A hydrodesulfurization and aromatization process （named as Hydro-GAP） was developed by the Luoyang Petrochemical Engineering Corporation to reduce the sulfur and olefin contents in FCC naphtha and without octane loss. The catalyst used in the process had both good hydrogenation and aromatization activities. The octane loss during hydrodesulfurization was successfully refrained with said catalyst. The test results from a 100mL unit showed that the average desulfurization rate of FCC naphtha was 85% with a total C5^＋ liquid yield of more than 95% the RON, MON and antinock index of the treated naphtha were increased by 0. 2- 0. 6 unit, 1. 3- 1. 8 units and 1. 0 unit, respectively. The activity of the regenerated catalyst was almost the same as the fresh catalyst. The evaluation results of Hydro-GAP catalyst running for 7 800 h and its regenerated catalyst running for 3 200 h indicated that the stability and the regeneration performance of the catalyst were excellent.
