摘要
以Co，Mo，Ni为活性组分，改性Al2O3为载体，采用浸渍法制备出裂解汽油二段加氢催化剂LY-9802。在360mL绝热床评价装置上，对该催化剂与进口同类型催化剂进行了性能对比实验，并在34万t／a汽油加氢装置上进行了工业应用。结果表明，LY-9802催化剂的加氢、脱硫及稳定性能均优于进口催化剂；在工业装置上稳定运转17个月，未进行再生，入口温度控制在273～283℃，加氢产品的溴价小于0．01g／g，含硫质量分数小于1×10^-6，床层温升集中在30～40℃。
The catalyst LY -9802 for the second- stage pyrolysis gasoline hydrogenation was prepared by impregnation method with Co, Mo, Ni as active constituents and modified Al2O3 as carrier. The performances of LY -9802 were compared with a same kind of imported catalyst in a 360 mL adiabatic reactor evaluation device, and LY -9802 was applied in a 340 kt/a gasoline hydrogenation plant. The results showed that the hydrogenation and desulfurization performances and stability of LY -9802 were superior to imported catalyst. The catalyst had run steadily for 17 months without regenerantion,the entrance temperature was between 273 -283℃,the bromine value of hydrogenation product was less than 0. 01 g/g,the mass fraction of S was less than 1 ×10^-6, and the temperature rise of bed was between 30 -40℃.
