Abstract: A new process consisted of expansion bed-catalytic distillation series process (LNE-3) developed 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 conversion 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.

Key words: Etherification, FCC gasoline, tertiary olefin, conversation, octane number
