在低温变压条件下测量了5A和13X沸石分子筛对CH4/CO2混合气体的分离能力。实验研究了CH4/CO2气体流量、吸附压力、填料高度和吸附温度对穿透曲线和分离能力的影响。研究结果表明,增大气体流量、增加吸附压力会降低分离效果,减小混合气体的分离系数;降低吸附温度、增加填料高度有利于CH4/CO2分离,提高混合气体的分离系数;在相同实验条件下,13X沸石分子筛对CH4/CO2混合气体吸附分离能力高于5A分子筛。
Abstract：The separation performance of zeolite 5 A and 13 X molecular sieves on CH4/CO2 mixture was measured by single column breakthrough curves. The effects of CH4/CO2 gas flow rate, adsorption pressure, adsorption temperature and packed height on the breakthrough curves and separation performance were investigated. The experimental results show that the separation capacity was reduced as the gas flow rate increasing and the adsorption pressure increasing. Decreasing the adsorption temperature and increasing the packed height favorable for the separation. Under the same experimental conditions, the adsorption and separation ability of 13 X zeolite molecular sieve was higher than that of 5 A molecular sieve.
