煤化工工艺过程CO_2排放分析及其减排技术

Analysis of Carbon Dioxide Emissions and Its Reduction Technology in Coal Chemical Industry

分析了煤化工产业中煤制甲醇、煤直接液化和间接液化、煤制烯烃等工艺过程中CO_2的排放,并介绍了3种CO_2减排技术:CO_2收集和储存技术、CO_2循环利用技术和CO_2化学转化技术。应高度重视CO_2化学转化技术的开发,把CO_2化学转化为附加值高的化学品。

Carbon dioxide emissions from such coal chemical process units as coal-to-methanol, direct coal lique- faction, indirect coal liquefaction and coal-to-olefin was analyzed in the paper. Three different CO2 emission reduction technologies were introduced, namely： CO2 collecting and storing technology, CO2 recycle utilization technology and CO2 chemical conversion technology. It is considered that by using carbon dioxide to produce high value-added chemicals through chemical conversion can realize the CO2 emissions reduction in the coal chemical industry.
