In order to understand the desorption characteristics of decarbonization solution, desorption kinetics of decarbonization solution using ammonia method in carbon capture was investigated. The desorption reaction mechanisms of decarbonization solution was analyzed firstly. The kinetic experimental results indicated that two reaction stages, rapid and slow reaction zones involved in desorption reaction. The experiments also proved that the desorption reaction was a second order reaction, the activation energy and reaction rate constant were 67.5 kJ mol(-1) and 9.8 x 10(6) exp (-8113/T), respectively.
