[Abstract]:The preparation method of 13X zeolite zeolite supported potassium based CO_2 absorbent was introduced. The microstructure of 13X zeolite was analyzed by scanning electron microscope and the regeneration reaction characteristics were studied by thermogravimetric analysis. The effects of different reaction end temperature and heating rate on regeneration reaction characteristics were investigated and the parameters of regeneration reaction characteristics were obtained by means of thermal analysis kinetics method. The results showed that the apparent structure of absorbent was improved after KHCO3 was loaded on zeolite molecular sieve, and the reaction rate was increased when the final temperature of decomposition was increased, but the effect was not obvious when the temperature was higher than 200 鈩，
