Optimization of Carbon Dioxide Adsorption Process by Micro-Porous Polymer Adsorbent

Hyperlinked polymers (HCPs) are one of a variety of microporous polymers with a pore size of about nm, which is very important for the capture and storage of carbon dioxide. In this work, benzene-based HCP adsorbents synthesized on the basis of the Friedl-Kraft reaction have been investigated experimentally for the capture of carbon dioxide. The surface-response method was used to optimize process parameters to increase the carbon dioxide absorption capacity. The pressure, temperature, Kraselinker to benzene ratio, and synthesis time as process parameters and absorption capacity are also considered as the response of this method. The optimal values of pressure, temperature, Kraselinker to benzene ratio, and synthesis time, which maximize absorption capacity, are 5.857 bar, 21.331 ° C, 2.189, and 14.357 h, respectively. According to the optimum condition, the absorption capacity of carbon dioxide was calculated as 244.43 mg/g of adsorbent.
