摘　　要：在广州石化汽油加氢装置中进行了二段加氢国产催化剂LY-9702和LY-9802的工业应用。结果表明,催化剂LY-9702和LY-9802具有低温加氢脱硫活性高、加氢稳定性能优良等特点,连续运行32个月后,反应器入口温度从使用初期的232℃缓慢上升至265℃;加氢汽油的溴价较低,最高不超过0.70 mg/g,含硫质量分数则小于0.5×10-6。与同类进口催化剂LD-145和HR-406相比较,使用催化剂LY-9702和LY-9802时,反应器入口温度低、加氢汽油的溴价低、运行周期约可延长2年,其综合性能尤其是加氢稳定性能超过进口催化剂。Industrial application of double bed used catalysts LY-9702 and LY-9802 were carried out in the second-stage of pyrolysis gasoline hydrogenation unit of Guangzhou Petrochemical Cor- poration. The results showed that the catalysts of LY-9702 and LY-9802 had high hydrodesulfu- rization activity at low temperature and excellent hydrogenation stability. The inlet temperature of reactor had been raised slowly from 232℃ to 265℃ after continously running for 32 months. The bromine value of hydrogenation gasoline was low that the highest value was less than 0.70 mg/g, suffer mass fraction was less than 0.5×10^-6. Compared with the impor- ted catalysts LY- 145 and HR-406, both inlet temperature of reactor and bromine value of hydrogenation gasoline were lower and running period would been prolonged for two years when LY -9702 and LY -9802 were used. The comprehensive performances of the catalysts LY- 9702 and LY- 9802, especially hydrogenation stability, had exceeded the imported catalyst.
