Abstract:

The single-component isothermal adsorption curves of CO2 and CH4 n zeolites 5A,13X and 13X-APG were measured by static volumetric method.The adsorption temperature and adsorption pressure on adsorption capacity were investigated.The experimental results showed that the adsorption of CO2 and CH4  increased as the adsorption temperature decreased and the experimental pressure increased.The adsorption capacity of the three zeolite molecular sieves on CO2 was larger than that of CH4.At -30 ℃,the saturated adsorption capacity of CO2 and CH4 on the adsorbent used was the highest,the adsorption capacity of CO2 were 4.94,6.52,6.35 mmol/g,the adsorption capacity of CH4 were 3.00,3.25,3.79 mmol/g.The regeneration performance of 13X-APG zeolite was at 200 ℃ for 180 mins  good and met the requirement of regeneration of adsorbent.

Key words: molecular sieve, static volumetric method, cryogenic adsorption, adsorption equilibrium
