Abstract: Adsorption and separation by carbon molecular sieves is improves the detection sensitivity of radio xenon measurements.However,the adsorption capability including the adsorption column volume and the gas recovery are influenced by the CO₂ in the air.Therefore,the CO₂ must be removed before the xenon adsorption.This study analyzed CO₂ removal by zeolite molecular sieves for various operating conditions.The results show that the 13 XHP zeolite molecular sieve more effectively removes CO₂ than the other adsorbents and that the CO₂ temperature and volume fraction are the most important of fact affecting the adsorption performances.The inlet pressure and flow rate have less effect on the adsorption of CO₂ by 13XHP for how rates of 564—2 015 mL/min and pressures of103—353kPa.
