Abstract: In this paper，the 1st stage hydrogenation production of cracking C9 gasoline from Dushanzi Petrochemical Company is used as raw material and industrial equipment conditions was simulated. The results of stability and 1000 h activity of LY-C9-B and contrast-catalyst show that bromine value of LY-C9-B product is much lower and the bed temperaturing is 5 ℃ higher than that of contrast-catalyst even when inlet temperature of LY-C9-B is 10—15 ℃ lower than that of contrast-catalyst. The results indicated that desulphurization effect of LY-C9-B is better than that of contrast-catalyst. Thus，comprehensive properties of LY-C9-B are superior to contrast-catalyst. Meanwhile，the hydrogenation products of LY-C9-B can be used as solvent oil after cutting. The catalyst shows a predictable industrial application prospect.

摘要： 以独山子石化裂解汽油C₉馏分一段加氢产品为原料，模拟工业装置工况，LY-C₉-B与对比催化剂1000 h活性和稳定性试验结果表明：在其它工艺相同条件下，LY-C₉-B入口温度比对比剂低10～15 ℃、床层温升高5 ℃，LY-C₉-B产品溴价明显低于对比剂，LY-C₉-B催化剂脱硫效果比对比催化剂略好，因此LY-C₉-B综合性能明显优于对比剂；同时其加氢产品经切割后，可以作为不同溶剂油使用，具有十分良好的工业应用前景。
