Fits of the 1-D axial dispersed plug flow model to the 97.5% location (diamonds) experimental centerline gas-phase concentration breakthrough curves for CO2 (left) and H2O vapor (right) on zeolite 5A and corresponding predictions from the model of the 2.5% (circles) and 50% (squares) locations. Diamonds: experimental data; dashed lines: simulations with the Edwards and Richardson correlation for axial dispersion (eq 10a) and corresponding kn values (Table 5); dotted lines: simulations with the Wakao and Funazkri correlation for axial dispersion (eq 10b) and corresponding kn values (Table 5). The saturation term in the CO2-zeolite 5A isotherm was increased by 15%. The saturation term in the H2O vapor-zeolite 5A isotherm was decreased by 3%. The void fraction was reduced to 0.33 based on the Cheng distribution39 with C = 1.4 and N = 5, as recommended by Nield and Bejan.40
