In this work, we report carbon adsorbents prepared using MCM-41 (mesoporous zeolite) template and high nitrogen content, melamine-formaldehyde resin as starting material by using nanocasting technique. The material was carbonized and physically activated with CO2 at different temperatures to obtain different carbon adsorbents. Synthesized adsorbents were characterized using various techniques for their elemental, surface and textural properties. Effect of nanocasting technique was seen by the improvement in textural property e.g. the surface area and pore volume of the adsorbent prepared at 700 degrees C were found to be maximum, i.e. 193.28 m(2) g(-1) and 0.32 cm(3) g(-1), respectively. This was not seen for the sample prepared by direct carbonization (MF-700). Also, development of nanostructured carbon adsorbents was confirmed from XRD and TEM results. Adsorption of CO2 on carbon adsorbents was evaluated at different temperatures (30-100 degrees C) and concentrations (5-12.5%) in a dynamic fixed bed column. Adsorbent prepared at 700 degrees C exhibited highest CO2 uptake of 0.64 mmol g(-1) due to high basicity as confirmed from X-ray photoelectron spectroscopy. Both surface and texture chemistry have a strong influence on the CO2 adsorption performance. The CO2 adsorption kinetic study was performed by using three kinetic models and was found that a fractional order fits well with the experimental data with.maximum error% of 3.68%. Regeneration study of the adsorbent was carried out by using multiple adsorption-desorption cycles and found that the adsorbent exhibited easy regenerability and stability over multiple cycles. The Temkin isothermal model fitted best among three isotherm models indicating the heterogeneous surface of adsorbent surface. The isosteric heat of adsorption is found to be 15.05 kJ mol(-1), which indicates physiosorption process and also supports easy regenerability of the adsorbent. Thermodynamic parameters such as Delta H-0 and Delta S-0 were found to be -5.7 kJ mol(-1) and 0.033 kJ mot(-1) K-1. The thermal energy estimated for CO2 desorption is 2.15 MI per kg CO2.
