| 英文摘要: | Global greenhouse gases emissions have increased tremendously since 1950's due to excessive burning of fossil fuel. The objective of this work is to develop and investigate packaging waste-derived activated carbon for carbon capture. Activated carbon was synthesized by carbonization of peanut-shaped packaging waste followed by chemical activation using KOH at a ratio of one to four. The activated carbon was characterized for it is textural properties using N2 adsorption at 77K, and carbon dioxide adsorption isotherms at 273, 298 and 323K. Non-Linear Density Functional Theory (NDLFT) was applied to carbon dioxide isotherm at 273K to characterize narrow micropores and microporous structure of activated carbon. Field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) were used to investigate morphology and microstructure. TEM micrographs confirmed the existence of random micropores. We have also noticed that the textural properties were highly dependent on the concentration of the activating agent. Carbon dioxide adsorption on activated carbon materials has shown dependency on the volume of narrow micropores (less than 0.8nm). The activated carbon materials have narrow micropore volume in a range of 0.155-0.292 cm3, and BET surface area of 761-1383 m2/g. Carbon activated with KOH ratio of three (WDC-03) has shown excellent CO2 uptake of 5.33 and 4.24mmol/g at 273 and 298K respectively. Moreover, it has also shown a high value for the isosteric heat of adsorption (29.8-14.3 KJ/mol) and selectivity of ∼16 over nitrogen. © 2018 Elsevier Ltd. All rights reserved. |
