苯乙烯的生产趋势及应用研究

文章介绍了苯乙烯的主要生产工艺方法,以乙苯脱氢法为主,提出裂解汽油企业需加速溶剂抽提法技术改造。对我国苯乙烯供需市场进行了分析,2013年产能达7000 KT/a,在建和计划装置产能达5000 KT/a以上,预计近期供需基本平衡,计划筹建项目需慎重考虑。苯乙烯用途广泛,主要用于制造聚苯乙烯塑料(PS)、ABS树脂、丁苯橡胶、离子交换树脂等,需进一步开发环保和高性能的工业、农用及家庭消费品。

The Trends of the Production and Application of Styrene

The paper introduces the main method for the production of styrene, Catalytic dehydrogenation of ethylbenzene is an important method for production of styrene, the pyrolysis gasoline enterprise needs to accelerate the technological transformation of solvent extraction method. On China＇s styrene market supply and demand are analyzed, In 2013 the production capacity was 7.0 million tons/a, in build and plan thtproduction capacity in building and planning reached more than 5.0 million tons/a, it is expected that the recent demand basically in balance, the planning and construction of the project should be considered carefully. Styrene was widely used, mainly used in the manufacture of polystyrene （PS）, Acrylonitrile Butadiene Styrene, Emulsion-polymerized styrene butadiene rubber, such as ion exchange resin, the need of the further development of environmental protection and high performance industrial, agricultural and domestic consumer goods.
