abstract:
A highly stable MOF-based adsorbent Zr-FUM was selected to separate CH4/C2H6, C2H6/C3H8, C2H2/C2H4 and C2H4/C3H6 gas mixtures,which have difficulty in their separation.Adsorption heat and adsorption selectivities were calculated based on the single-component adsorption isotherms.Combined with swing adsorption separation device,the separation performance of light hydrocarbons was investigated.Finally,the stability and cycling performance of Zr-FUM were systematically tested.The results show that,Zr-FUM exhibits excellent separation performance of light hydrocarbons,with the breakthrough time 8,10,5,11 min for the 4 groups of gas mixtures above;Zr-FUM exhibits good stability,for the structure of Zr-FUM could not be destroyed under the mechanical pressure of 2 MPa,temperature of 100℃,and water vapor environment with 36 h;Zr-FUM exhibits good regenerability for the breakthrough profiles were well retained after 10 cycles of gas mixture separation.
