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 × 106 exp (−8113/T), respectively.
► Kinetic of desorption in carbon capture using ammonia method was studied. ► The study shows some improvements on experimental method compared with others. ► The kinetic factors are gained through experiment and calculation.
