摘要:

煤制烯烃是近几年来盈利状况最好的现代煤化工产品,其发展动向引发石化行业关注。本文介绍了煤制烯烃尤其是经甲醇制烯烃技术的发展现状,探讨了煤制烯烃技术的发展趋势,并对煤制烯烃和外购甲醇制烯烃技术的经济性进行了分析,认为:目前煤制烯烃技术总体上成熟,已在我国得到大规模工业推广,但仍需加强技术创新,早日拥有具有自主知识产权的煤制烯烃全流程一体化成套技术。随着我国煤制烯烃产能快速增长,未来石油烯烃与煤制烯烃的竞争不断加剧,为此应立足行业实际,充分发挥石油化工与煤化工自身优势,加快技术研发与产品结构调整,实现产品结构差异化、高端化,促进石油化工与煤化工优势互补,推动我国化工行业高质量发展。

Abstract:

Coal to olefins is the most profitable modern coal chemical process in recent years, and its development trend has aroused widespread concern in the petrochemical industry. In this paper the development status of coal-to-olefins technology, especially methanol-to-olefins technology, was introduced, and the development trend of coal-to-olefins technology was discussed. It was concluded that coal-to-olefins technology was generally mature and had been applied in large-scale industrial production in China, but it still needed to be further improved, especially to speed up the technological innovation, so as to possess our own intellectual property rights in coal-to-olefin integrated whole-process technology as soon as possible. With the rapid growth of coal-to-olefin capacity in China, the competition between petroleum olefins and coal-to-olefins will be more intense in the future. Therefore, based on the reality of the industry, full play should be given to the advantages of petrochemical and coal chemical industries, and to speed up technological innovation and product structure adjustment. Efforts should be made to realize the differentiation and high-end structure of olefin products, to promote the complementary advantages of petrochemical and coal chemical industries, and to jointly promote the production of chemical products in China towards the goal of high-quality development.

Key words: coal-to-olefin, methanol-to-olefin, technology status, technology economy, development trend
