Adsorption equilibrium of CO2 and dimethyl ether on nanostructed materials were obtained by static volumetric method in the pressure range of 0 to 30 bar at 293.15, 303.15, and 313.15 K. Langmuir isotherm, Langmuir Freundlich isotherm and dual-site Langmuir isotherm were used to fit the adsorption equilibrium data of CO2 and dimethyl ether on carbonized Kapok adsorbent prepared from natural fiber. In addition, lithium-exchanged X type zeolite was used for comparison. It was found that carbonized Kapok has high adsorption capacity of CO2 and dimethyl ether. |
