adsorption of co2 on functionalized adsorbents with various amines in the fixed-bed column

In recent years, demand for solid carbon dioxide adsorbents with high adsorption capacity and stability has been risen. electrospinning is used to create polyacrylonitrile nanofibers for carbon dioxide adsorption. various amines, such as ethanolamine (ea), diethyl amine (dea), and triethyl amine (tea) were used for modification procedure. dynamic adsorption tests were performed on 5% co2 input feed in ch4 /co2 mixture. the carbon dioxide adsorption capabilities of ethanol amine (ea), diethyl amine (dea), and ethanol amine (tea) were 1.49 mmol/g, 0.707 mmol/g, and 0.58 mmol/g, respectively, at atmospheric pressure and ambient temperature. the findings reveal that the adsorbent with ea modification has a lot of promise for carbon dioxide adsorption.
