采用两段加氢工艺对裂解 C9进行了加氢处理，一段采用 Ni 系催化剂将易结焦的二烯烃、链烯基芳烃等热敏物质除去，并使部分单烯烃加氢饱和；二段采用 CoMoNi 系催化剂进行加氢脱硫同时将单烯烃加氢饱和。重点考查了反应温度、压力、氢油比、空速对一段加氢效果的影响，并初步探讨了二段反应温度对加氢性能的影响，研究结果表明两段加氢后的产品溴值小于2.0 g Br/100 g，总硫小于1.0μg/g，胶质含量小于5 mg/100 mL，可用于汽油调和组分或芳烃溶剂油。

The cracking C9 was hydrogenated by two-step hydrotreating.Nickel catalyst was used in the first-stage to eliminate heat sensitive materials such as diene and alkenyl aromatics,and some monoolefine was hydrogenated partially. The Co-Mo-Ni catalyst was used in the second-stage to carry out hydrodesulfurization, and residual monoolefine was hydrogenated. Effects of temperature, pressure, hydrogen-oil ratio and air speed on the hydrogenation reaction were investigated. The results shows that the cracking C9 after two-step hydrotreating can be used as composition of gasoline and aromatic solvent oil because its bromine number is less than 2.0 g Br/100 g, total sulfur is less than 1.0μg/g and the colloid content is less than 5 mg/100 mL.
