GARDES-Ⅱ器外完全硫化态催化剂在汽油加氢装置的工业应用

Commercial application of GARDES-Ⅱ external fully-vulcanized state catalyst in FCC gasoline hydrodesulfurization unit

GARDES-Ⅱ器外完全硫化态催化剂在某石化公司80万t/a汽油加氢脱硫装置上成功应用,与上一周期采用氧化态催化剂开工时相比,硫化态催化剂具有开工过程安全环保、流程简单且耗时短等优点。装置标定结果表明,GARDES-Ⅱ器外完全硫化态催化剂完全可以满足该装置生产国Ⅵ(A)标准汽油的要求,产品博士试验通过,硫质量分数平均为6.5μg/g,烯烃体积分数降低4.7%,研究法辛烷值(RON)损失为0.45个单位,汽油收率为99.05%。由此表明,GARDES-Ⅱ器外完全态硫化催化剂满足公司清洁汽油生产要求,具有良好的脱硫、降烯烃能力以及较好的辛烷值恢复功能。

GARDES-Ⅱ external fully-vulcanized state catalyst is successfully applied in a petrochemical company’s800 000 t/a gasoline hydrodesulfurization unit. Compared with the startup stage using an oxidation state catalyst,the start-up stage using the fully-vulcanized state catalyst is more safe,environmentally friendly,simple and quick.It can be seen from the calibration data that GARDES-Ⅱ external fully-vulcanized state catalyst can fully meet the requirements of the unit to produce gasoline meeting China’s national standard Ⅵ( A).The product has passed the doctoral test,and the mass fraction of sulfur is averaged at 6. 5 μg·g-1.The loss of research octane number( RON) is 0. 45 units,the olefin volume fraction reduces by 4. 7%,and the yield of gasoline reaches 99. 05%. Therefore,GARDES-Ⅱ external fullyvulcanized state catalyst meets the company’s clean gasoline production requirements,showing excellent abilities in desulfurization and reducing olefins,and good performance in recovering octane number.
