Adsorption of CO۲ on Functionalized Adsorbents with Various Amines in the Fixed-Bed Column

In recent years, demand for solid carbon dioxide adsorbents with high adsorption capacity andstability has been risen. Electrospinning is used to create polyacrylonitrile nanofibers for carbondioxide adsorption. Various amines, such as ethanolamine (EA), diethyl amine (DEA), and triethylamine (TEA) were used for modification procedure. Dynamic adsorption tests were performed on ۵%CO۲ input feed in CH۴ /CO۲ mixture. The carbon dioxide adsorption capabilities of ethanol amine (EA),diethyl amine (DEA), and ethanol amine (TEA) were ۱.۴۹ mmol/g, ۰.۷۰۷ mmol/g, and ۰.۵۸ mmol/g,respectively, at atmospheric pressure and ambient temperature. The findings reveal that the adsorbentwith EA modification has a lot of promise for carbon dioxide adsorption.
