Abstract—The increase in carbon dioxide (CO
2) emission into the atmosphere has become the key factors in an extend of the temperature rise, that eventually causes global warming and climatic change. Thus, low-cost coconut shell activated carbon was synthesized, and its applicability in CO
2 capture at 25
oC and 1 bar was tested. Utilization of coconut shells as precursors for activated carbon production is economically viable. The pore structure of synthesized and commercial activated carbon was evaluated by using the nitrogen physisorption. In addition, comparability of the CO
2 sorption capacity with the commercial activated carbon proposes that better-quality adsorbents can be produced by a single activation process. This chemically-free process is favorable as it promotes a cleaner pathway on the activated carbon development. Besides, the equilibrium data for CO2 adsorptions are well-fitted to Langmuir isotherm, with the maximum adsorption capacity is 49.75 and 70.42 cm3/g for both the synthesized and commercial activated carbon, respectively.
Index Terms—Activated carbon, carbon dioxide adsorption, Langmuir isotherm, waste biomass.
