摘　　要：GARDES-Ⅱ器外完全硫化催化剂在中国石油呼和浩特石化分公司(简称呼和浩特石化)1.2 Mt/a催化裂化汽油加氢脱硫装置上成功应用。应用结果表明,与氧化态催化剂开工相比,硫化态催化剂的开工过程安全环保、流程简单且耗时短。通过初期标定数据可以看出,GARDES-Ⅱ器外完全硫化催化剂完全可以满足呼和浩特石化现行工况下生产国Ⅵ(A)标准汽油的要求,产品通过博士试验,硫质量分数平均为7.1μg/g,研究法辛烷值(RON)损失1.1~1.3个单位,汽油收率达99.0%,装置能耗为516.23 MJ/t。其中,重汽油烯烃体积分数平均降低11.4百分点。由此表明,GARDES-Ⅱ器外完全硫化催化剂的加氢性能已达到器内硫化水平,具有良好的脱硫活性和辛烷值恢复功能。The GARDES-Ⅱ technique for gasoline hydrodesulfurization with ex-situ presulfided catalysts were applied in a 1.2 Mt/a HDS unit of FCC gasoline in PetroChina Hohhot Petrochemical Company and the results were introduced.Compared with the oxidized catalyst,the start-up using ex-situ presulfided catalyst is relatively safe,environmental friendly,simple and less time-consuming.The calibration data indicated that the gasoline produced by GARDES-Ⅱ ex-situ presulfided catalysts could completely meets the requirements of China Ⅵ(A)gasoline standard under the current conditions of Hohhot Petrochemical Company of PetroChina.The average sulfur content of the product was 7.1μg/g,the octane number loss was 1.1-1.3 units with the gasoline yield of 99.0%and energy consumption of 516.23 MJ t.In addition,the average olefin reduction of heavy FCC naphtha(HCN)was 11.4 percentage points.It is concluded that the GARDES-Ⅱwith ex-situ presulfided catalysts reaches the HDS level of in-situ presulfurization process and have good desulfurization activity and octane number recovery.
