燃煤发电排放CO2的处置利用途径

CO2是能源与环境生物活动循环的依存产物，工业化后煤炭等化石燃料的使用产生了大量的CO2排放，打破了CO2的自然生态平衡。介绍了CO2的来源，分析了燃煤发电CO2的排放量，我国每年燃煤发电约排放C0230．7×10^8t，指出燃煤发电是减排CO2的重点。提出CO2的利用与处置的方法主要有：CO2和合成氨加工成尿素，并发展大颗粒尿素促进造林绿化；美国正在建的CO2零排放燃煤发电装置，采用了CO2收集与封存（CCS）技术，以及煤制油清洁燃料联产电力。

Ways for CO2 Disposition Utilization Emitted from Coal Electric Power

CO2 is the product depending on the cycle of energy and environment biology activity.After industrialization,a large amount of CO2 emission resulted from application of fossil fuels which have broken the natural ecologic balance of CO2.The article introduces the origin of CO2,and analyses the CO2 emission volume from coal electric power which amounts 30.7×10^8t in China annually,thus reaching a conclusion that the key point for CO2 emission reduction is coal electric power.Finally the article puts forth the ways for CO2 disposition ＆ utilization emitted from coal electric power： ① producing synthetic urea with CO2 and synthetic ammonia producing,and promoting afforestation with the help of large-grain urea;② zero emission coal electric power installation adopting CCS technology and coal to oil clean fuel co-producing electric power plant constructed in America.
