摘要: To prevent CO2 accumulation in the atmosphere generated from scorching of fossil fuels, carbon capture and sequestration (CCS) technology is considered as a potential route to mitigate the emissions of CO2 from reaching the atmosphere. Power generation from sources such as gas, coal and biomass can fulfill the energy demand more readily than many other sources of electricity production. Thus these sources may be retained as important alternative option in the global energy cycle. In order to curtail CO2, porous aramid network was fabricated by the condensation of 1,3,5-benzenetricarbonyl trichloride and 1,3-phenylenediamine in 1,4-dioxane solvent. Aramid was characterized for various analyses including FTIR, XRD, TGA, BET surface area and pore size analysis, FESEM and CO2 adsorption measurements. Excellent thermal stability was provided by strong amide linkages in the polymer backbone. Optimum CO2 uptake of aramid was achieved to be 23.14 mg·g-1 at 273 K at 0.1 MPa. The basic amide groups of network structure showed greater affinity for CO2. Excellent thermal stability of aramid makes it a promising sorbent for CO2 capture in adverse conditions.
