Popis: We studied different face velocity and carbon dioxide (CO2) initial concentration to examine the adsorption behavior of calcium oxide (CaO) impregnated activated carbon (AC) filter and also to discuss pseudo-first-order, pseudo-second-order and intra-particle diffusion three kinetic models. The experimental results show that saturation time and saturation capacity were decreased and increased with higher inlet concentration at the same face velocity, respectively. Simulation results show that pseudo-second-order correlation coefficient (r22 = 0.921) is higher than pseudo-first-order (r12 = 0.7815) and intra-particle diffusion (ri2 = 0.905). Therefore, the adsorption process of CO2 onto CaO impregnated AC filter media is appropriate for the pseudo-second-order kinetic model.
