The Study of Sorption Capacity and Characterization on CO2 Capture Using Zeolite and Activated Carbon from Sugarcane Bagasse

Abstract

We evaluated the capture of CO2 using the combination of adsorbents: natural zeolite-(Z-Z), and activated carbon from sugarcane bagasse. The result suggested that CO2 adsorption using natural zeolite and and activated carbon from sugarcane bagasse are good. Characterization of the activated carbon and the zeolite was carried out by the following analysis: The Fourier Transform Infrared Spectroscopy (FTIR), The Scanning Electron Microscope (SEM), The X-ray Diffraction (XRD). The TGA ,while the activated carbon shows a better sorption capacity than the zeolite. The adsorption capacity of each of the masses are; 0.057, 0.060, and 0.065 mg/g with flow rate of 1l/min; 0.058, 0.061 and 0.068 mg/g with flow rate of 2l/min, and 0.055, 0.063 and 0.070 mg/g with flow rate of 3l/min at 50 minutes and 298 K for the activated carbon. And 0.048, 0.049 and 0.050 mg/g with flow rate of 1l/min; 0.048, 0.053 and 0.055 mg/g with flow rate of 2l/min and 0.048, 0.051 and 0.054 mg/g with flow rate of 3l/min at 50 minutes and 298 K for the zeolite. A very good and porous activated carbon with a high adsorption capacity produced from sugarcane bagasse and used in this work had a better CO2 adsorption capacity than zeolite, it can be suggested that activated carbon in CO2 adsorption is a better performer than zeolite for both commercial and laboratory use because of the larger pore size which enable it to be most effective in CO2 adsrption compare to zeolite while there are all sustainable and inexpensive
