Abstract: The importance of CO2 emission reduction is discussed，and the main methods of chemical utilization of CO2 is outlined. Three ways of ammonolysis reaction of carbon dioxide are reviewed. Ammonolysis reaction produces ammonium bicarbonate，urea and cyanuric acid. Production of cyanuric acid by ammonolysis of carbon dioxide is highlighted，and the thermodynamics is analyzed. The reaction characteristics are described，and ammonolysis of carbon dioxide to produce cyanuric acid and other solid products is a feasible way for chemicalutulization of carbon dioxide. Not only carbon dioxide can be sealed up，but also high added value products can be obtained. Combination of ammonolysis reaction and coal chemical industry will reduce emission of carbon dioxide effectively，and has a broad prospect.

Key words: carbon dioxide, ammonolysis reaction, cyanuric acid, chemical ultilization

摘要： 论述了减排CO2的重要性，概述了CO2化学利用的主要方法，综述了CO2的3种氨化反应，即氨化反应生成碳酸氢铵、尿素和三聚氰酸，重点介绍了CO2氨化反应生成三聚氰酸，对该反应进行了热力学分析，叙述了其反应的特点，得出CO2氨化合成三聚氰酸等固体产品是一条比较可行的CO2化学利用路线。氨化合成三聚氰酸不仅可以实现CO2的封存，而且能够实现CO2的高值有效利用，对解决CO2减排具有重要意义。认为将氨化反应与煤化工产业相结合，可以有效减少二氧化碳的排放强度，具有广阔的发展前景。
