An evaluation of carbon-based adsorbents for post-combustion CO<SUB align=right>2 capture

English (OpenAlex)

This study aims to select the most suitable carbon-based adsorbent to be used in post-combustion CO2 capture by using multi-criteria decision-making (MCDM). Biochar, biomass-derived activated carbon, multi-walled carbon nanotube, and graphene adsorbent alternatives were evaluated based on five criteria. The criteria were weighted using the simple multi-attribute rating technique and criteria importance through inter-criteria methods. The analytic hierarchy process and the complex proportional assessment techniques were applied to the weighted criteria. As a result, biomass-derived activated carbon ranked first in all the applied methods. The novelty of the study is the prioritisation of carbon-based CO2 adsorbents with the MCDM approach.
