摘　　要：中国石油吉林石化公司采用中国石油兰州化工研究中心开发的膨胀床-催化蒸馏串联工艺建成300kt/a轻汽油醚化装置。装置运行8个月后进行了工业标定,结果表明:装置在满负荷运行情况下,C_5和C_6的叔碳烯烃平均转化率分别为91.33%和48.15%,甲醇消耗量为3.21t/h,醚化产品油辛烷值(RON)达到98.5,装置能耗为1 107.878 MJ/t,均符合设计指标要求,生产出合格的醚化轻汽油。A new process consisted of expansion bed-catalytic distillation series process （LNE-3）de- veloped by PetroChina Lanzhou Petrochemical Research Center was applied to a 300 kt/a newly-built FCC light naphtha etherification unit in PetroChina Jilin Petrochemical Company. The industrial calibration results after running for 8 months showed that under full load operating conditions,the average con- version of tert-C5 and C6 olefins was 91.33% and 48.15%, respectively, the consumption of methanol was 3.21 t/h,the RON of etherified oil reached 98.5,the energy consumption was 1 107. 878 MJ/t and the qualified etherified light gasoline was produced.
