Abstract: This paper reviewed and analyzed the progress on research and technology of conversion and utilization of CO2 by chemical route in recent years. CO2 can be converted into liquid fuel，methanol，carbonates，and other high value products through proper chemical reactions. CO2 can also be converted to olefin or oxygen-containing compounds through the process of CO2 – Methane synthesis. Other new technologies of CO2 utilization，including direct conversion of CO2 into oxygen through rational designed chemical lungs，conversion of CO2 into useful chemicals by solar energy，electricity and biological microalgae technologies，and progress of CO2 utilization as new hydrogen storage materials.

Key words: utilization of carbon dioxide, chemical transformation of carbon dioxide, value-added products from carbon dioxide

摘要： 近年来CO2的综合利用越来越引起人们的重视。本文介绍了近年来通过化学途径实现CO2资源化利用的研究方向及进展，并报道了最新的研究技术和成果。通过适当的化学反应，CO2可以转化为液体燃料、甲醇、碳酸酯类等高附加值的产品，还可通过CH4–CO2催化重整制成合成气来制备乙烯或含氧化合物等。另外，本文还介绍了其它新型CO2化学利用技术，如通过合理设计的化学肺可将CO2直接转换为氧气，利用太阳能、电能和生物微藻技术实现CO2向有用化学品的转化以及作为新型储氢材料的研究利用进展。
