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7.1 μg/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。

Abstract: The GARDES-Ⅱtechnique for gasoline hydrodesulfurization with ex-situ presulfided catalysts were applied in a 1.2 Mt/a FCC gasoline HDS unit of PetroChina Hohhot Petrochemical Company and the results were introduced. Compared with the oxidized catalyst, the ex-situ presulfided catalyst has the superiorities of safe, environmental friendly, simple and less time-consuming in the start-up stage. 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 by Doctor Test was 7.1 μg/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 cracked naphtha（HCN）was 11.4 percentage point. It is concluded that the GARDES -Ⅱ with ex-situ presulfided catalysts reaches the HDS level of in-situ presulfurization process and have good desulfurization activity and octane number recovery.
