文章介绍了近年来国内外基于煤经甲醇制烯烃的工艺技术路线,主要是煤制乙烯、丙烯工艺。对原料状况、国内需求和生产、市场前景,以及煤基烯烃工艺催化剂研究和技术经济等进行了简单论述。我国发展煤基烯烃具有坚实的基础,同时也呈现出了很好的经济和社会效益。 In this paper, the technological routes of coal-to-methanol-to-olefins at home and abroad in recent years are introduced, mainly including the processes of coal ethylene and propylene. The conditions of raw materials, domestic demand and production, market prospects, as well as coal-based olefin catalyst and technical and economic research were briefly discussed. China’s development of coal-based olefin has a solid foundation, but also showed a very good economic and social benefits.
