dc.description.abstractCombating climate change and global warming focuses generally on eliminating carbon emissions from energy production or transportation. For this purpose, CO2 capture, storage and utilization technologies were developed to remove or uptake carbon from the atmosphere. Here, porous carbon particles (PCPs) were prepared via hydrothermal and carbonization methods from various disaccharides sources, sucrose (S) as S-PCPs, lactose (L) as L-PCPs, and maltose (M) as M-PCPs as adsorbents for CO2 capture. Surface areas, pore volumes, and pore sizes of all adsorbents were determined using the N-2 adsorption-desorption method and as S-PCP is the adsorbent with the highest surface area, 460 m(2)/g exhibited the highest CO2 capture capacity which are 3.58 +/- 0.03 mmol CO2/g absorbent at 273 K and 2.48 +/- 0.02 mmol CO2/g absorbent at 298 K at about 1 atm pressure. Furthermore, S-PCP was found to be practically completely stable for at least 10 successive uses and the adsorption capacity >90 % at the end 10th use. More importantly, S-PCPs can be re-activatable by simple NaOH treatments at the end of 10 times adsorption-desorption cycle via simple NaOH treatment. Here, S-PCP particles after 10 repetitive uses were re-activated and continued to total 15th CO2 adsorption-desorption and CO2 adsorption capacity decreased to only 82 +/- 1.6 % of its first use.
