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110×10^(4 )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。This paper introduces the application of GARDES-Ⅱexternal complete vulcanization series catalysts jointly developed by China Petroleum and Petrochemical Research Institute,China University of Petroleum and Fuzhou University in the 110×10^(4) t/a catalytic cracking gasoline refining unit of Sichuan Petrochemical Company to produce vehicle gasoline blending products that meet the nationalⅥgasoline standard(sulfur≤10 mg/kg,olefins≤18%).The unit will run continuously for six years without any catalyst treatment from the first start of production in 2016 to 2022.GARDES-Ⅱoff-site vulcanization catalyst is selected for this commencement.The commencement time is short,and the actual commencement time is only 20 hours.The process is stable and controlled;Only 3 hours after switching to fresh raw materials,qualified products will be produced,in which the total sulfur content is 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 the mercaptan sulfur was only 2.67 mg/kg.After passing the doctor's experiment,the olefin content was reduced by 3%,and the RON loss of the research method was 0.9 units,the gasoline yield could reach 99.63%,and the energy consumption of the unit was 17.38 kgEo/t.It can be seen that GARDES-Ⅱtechnology fully meets the requirements ofⅥ(B)and even higher standard gasoline in the production country of PetroChina Sichuan Petrochemical Company.
