国内1-丁烯产能及生产工艺研究

Domestic 1-butene Production Capacity and Technology

1-丁烯是一种化学性质较活泼的α-烯烃,用途十分广泛,是一种重要的化工原材料。过去十年国内1-丁烯持续呈净进口状态,且随着中国化工产业不断发展,以及国内对油品添加剂、高级润滑油等1-丁烯下游产品需求量的增加,进口量逐年递增。国内目前生产1-丁烯方法有C4分离、丁烯异构化法及乙烯二聚法,其中以C4分离法为主。

1-butene is a kind of chemically activeα-olef in and important chemical materials with a wide range of uses.In the past ten years,1-butene has been in a state of net import in China.With the development of domestic chemical industry,the deep research of 1-butene downstream products development and utilization,the import volume has increased year by year.The current domestic production methods for 1-butene include C4 separation,butene isomerization and ethylene dimerization,among which C4 separation is the main method.
