Abstract
Both experimental and numerical investigations were performed to examine the impact of vapor on the dynamic adsorption of CO(2) in a horizontal fixed column filled with a novel activated carbon material. Experiments were conducted to examine how vapor impacts the CO(2) adsorption capacity of the newly developed activated carbon utilizing a DVS machine. Dynamic measurements of the separation of CO(2) from CO(2)/N(2) mixtures were conducted under room temperature and atmospheric pressure conditions using a breakthrough experiment. The data obtained from these experiments were then used to validate the numerical model. A parametric numerical study was carried out to investigate the effects of the flow rate, gas temperature, and bed humidity on the CO(2) uptake. Results obtained from dynamic vapor sorption (DVS) testing indicate the presence of a constrained adsorption force within the initial monolayer, a characteristic feature reminiscent of a type V isotherm. The numerical findings disclose that the adsorption process efficiency of the synthesized adsorbent is approximately 89%. A 20% increase in the flow rate leads to a 17% decrease in the breakthrough time, and a 20% increase in bed humidity results in an 8% decrease in the breakthrough time due to limited vapor adsorption by the material.
