供求烯烃市场在经历了多年的供过于求之后,现在已逆转为供不应求,而且,尽管有新的生产设施将投入运行,供不应求的局面看来还将持续下去。短链烯烃的供应是最吃紧的,特别是己烯(C6)、辛烯(C8)和癸烯(C10)。烯烃市场正迅速扩大,对己烯和辛烯的需求(它们是生产聚乙烯时使用的共聚单体)正以每年10%～14%的速度增长。长链α-烯烃的需求也在强劲增长,
The supply and demand olefins market has experienced a period of oversupply after it has been oversupply for many years, and it has now reversed its demand. In addition, despite the fact that new production facilities will be put into operation, the situation of supply shortages will continue to persist. The supply of short-chain olefins is the most severe, especially hexene (C6), octene (C8) and terpenes (C10). The olefins market is rapidly expanding and the demand for hexene and octene, which are comonomers used in the production of polyethylene, is increasing at a rate of 10% to 14% per year. Demand for long-chain alpha-olefins is also growing strongly.
