Abstract

Here in this work, gum arabic tree seed shell (bio mass) was utilized to synthesize carbon adsorbents by chemical activation methods at constant carbonization temperature. The properties of the carbon adsorbents were estimated through characterization techniques such as X-ray diffraction, Fourier Transform Infrared spectroscopy, Laser Raman spectroscopy, Field Emission Scanning electron microscopy, CHNS-elemental analysis and N2 adsorption studies. Gum arabic tree seed shell–derived carbon adsorbents were examined for CO2 capture in 25 to 70 °C temperature range. The characterization results indicated that these carbons contain high surface area with micro porosity. Among all the carbons, the carbon prepared after treatment of KOH to biomass ratio is 3:1 followed by and carbonization at 750 °C exhibited high adsorption capacity of 3.42 m.mol/g at 25 °C. The reason for high adsorption capacity of the adsorbents mainly depended on surface area (1472 m2/g) and micropore volume. The adsorbents showed easy desorption and recyclable up to five cycles with consistent activity.
