在高油价和能源供应紧张的趋势下,新型煤化工为中国未来油气资源的补充和部分替代开辟了新方向.煤制烯烃的成功商业化,使煤制烯烃的产品真正走向了市场并和国内外石化产品同台竞争,这将对我国能源化工原料供应结构产生深远影响.文章着重分析了我国煤制烯烃项目的概况、建设煤基甲醇制烯烃的理由,得出了煤制烯烃项目具有竞争力.“,”The trend of high oil prices and energy supply, new coal chemical industry has opened up a new direction for the future of China's oil and gas resources to supplement and alternative. Successful commercialization of coal-to-olefins, Coal to olefin products really go to the market, and petrochemical products at home and abroad to compete on the same stage, China's energy and chemical raw materials supply structure which will have a profound impact.The article focuses on an overview of China's coal-to-olefins project , with the construction of coal-based methanol to olefins reason, The coal-to-olefins project competitive.
