- 摘要：介绍了中国石油兰州研究中心、中国石油大学和福州大学合作开发的GARDES-Ⅱ器外完全硫化系列催化剂在四川石化公司110×104 t/a催化裂化汽油精制装置生产国Ⅵ汽油标准（S≤10 mg/kg，烯烃≤18%）的车用汽油调和产品中的应用情况。该装置自 2016年首次开工至2022年，未经任何催化剂处理的情况下连续运行6 a。此次开工选用的GARDES-Ⅱ器外硫化催化剂开工时间短，实际开工仅用 20 h，过程平稳、受控；切换新鲜原料 3 h即产出合格产品，其中总 S含量仅为 1.8 mg/kg。初期标定数据表明，混合产品中 S含量平均为 3.57 mg/kg，硫醇硫为 2.67 mg/kg，博士实验通过，烯烃含量有 3% 的降低，研究法辛烷值 RON 损失为 0.9 个单位，汽油收率能达到 99.63%，装置能耗为 17.38 kgEo/t。可见，GARDES-II技术完全满足中国石油四川石化公司生产国VI（B）乃至更高标准汽油要求。Abstract: This paper introduces the application of GARDES-Ⅱ external complete vulcanization series catalysts jointly developedby China Petroleum and Petrochemical Research Institute, China University of Petroleum and Fuzhou University in the 110×104 t/acatalytic cracking gasoline refining unit of Sichuan Petrochemical Company to produce vehicle gasoline blending products that meetthe national Ⅵ gasoline standard (sulfur≤10 mg/kg, olefins≤18%). The unit will run continuously for six years without any catalysttreatment from the first start of production in 2016 to 2022. GARDES - Ⅱ off-site vulcanization catalyst is selected for thiscommencement. The commencement time is short, and the actual commencement time is only 20 hours. The process is stable andcontrolled; Only 3 hours after switching to fresh raw materials, qualified products will be produced, in which the total sulfur contentis only 1.8 mg/kg. The initial calibration data showed that the average sulfur content in the mixed product was 3.57 mg/kg, and themercaptan sulfur was only 2.67 mg/kg. After passing the doctor's experiment, the olefin content was reduced by 3%, and the RONloss of the research method was 0.9 units, the gasoline yield could reach 99.63%, and the energy consumption of the unit was17.38 kgEo/t. It can be seen that GARDES-Ⅱ technology fully meets the requirements of Ⅵ (B) and even higher standard gasolinein the production country of PetroChina Sichuan Petrochemical Company.
