煤化工发展方向——煤制烯烃

Development Trend of Coal Chemical Industry——Coal to Olefin

叙述国内外甲醇制乙烯、甲醇制丙烯技术和工业化进展。认为我国合成气经二甲醚制取低碳烯烃(SDTO工艺)及其配套催化剂总体上达到了国际上技术领先水平。指出当前国际金融危机和石油价格大起大落之际,采取成熟的煤制烯烃技术生产丙、乙烯,减少原油进口,谋求石油供求平衡处于可控状态,减少外汇风险,提高国家能源安全,意义重大。

To describe the process technologies and industrialization situation of ethylene and propylene from coal-based methanol at home and abroad. To introduce the China advanced process technology CSDTO process and its catalysts. It is important to produce ethylene and propylene by using CTO process, to decrease oil imports and lower foreign exchange risk, to balance the oil demand and supply relationship, to safeguard national security of energy resources under the current international financial crisis with undulated oil price.
