制备烯烃的各类原料的现状与发展前景

Current Status and Development Prospect of Various Materials for Olefin Production

长期以来,生产乙烯的原料主要为石油和天然气。目前油气价格飞涨、资源日益匮乏,非油气的多元化资源的开发利用受到各国广泛重视。文章综述了生产烯烃的各类原料的现状及发展前景。现阶段以油气资源为原料的蒸汽裂解工艺是生产乙烯的主要手段,乙醇制烯烃工艺在巴西获得重大突破,煤制烯烃工艺正在中国实现工业化,将获得较大发展。

The main materials for olefin production have long been petroleum and natural gas, but due to the rapid raising of petroleum and gas price and increasingly starvation of resources in recent years, development and application of non - oil and non - gas diversified resources have been attached importance by all the countries. The current status and development prospect of various materials for olefin production were reviewed. At the present stage, steam cracking process with oil and gas as material is the main measure for ethylene production ; ethanol to olefin process has gained important breakthrough in Brazil; coal to olefin process is in the process of industrialization in China, and is going to achieve greater development in China.
