摘　　要：中国石油大庆石化公司330 kt·a-1乙烯装置是我国较早成套引进的乙烯装置。该装置碳二加氢一段反应器采用等温反应器,列管之间使用丁烷为冷却介质。第一段反应器采用新型LY-C2-12D催化剂,运转初期乙烯选择性为80%,运行6个多月,平均选择性达70%,表明该催化剂具有良好的稳定性。330 kt · a-1ethylene plant in PetroChina Daqing Petrochemical Co. is one of the earliest imported ethylene plants in China. The isothermal reactor is applied as C2 hydrogenation reactor and butane is used for cooling medium among the tubes. The new LY-C2-12D catalyst was applied in the first stage reactor. The selectivity to ethylene reached 80% in initial running period, and the average selectivity was up to 70%, which indicated that the catalyst possessed good stability.
