CO2 on zeolite 5A (top panels): Predictions from the model
(lines) shown in Figure 6 of the 2.5%
(circles), 50% (squares), and 97.5% location (diamonds) experimental center line
gas-phase concentration breakthrough curves but now using the reported
saturation term for the CO2-zeolite 5A isotherm (no adjustment), a
void fraction of 0.33, the Wakao and Funazkri correlation (eq 10a) for axial dispersion and LDF
kn = 0.0023
s−1. The experimental outside the bed (triangles)
breakthrough curve is shown for comparison. Predictions from the model (lines)
of the 2.5% location (circles), 50% location (squares), and 97.5% location
(diamonds) experimental center line temperature profile histories.
H2O on zeolite 5A (middle panels): Predictions from the model (lines)
shown in Figure 6 of the 2.5% location
(circles), 50% location (squares), and 97.5% location (diamonds) experimental
center line gas-phase concentration breakthrough curves but now using the
reported saturation term for the H2O-zeolite 5A isotherm (no
adjustment), a void fraction of 0.33, the Wakao and Funazkri correlation (eq 10b) for axial dispersion and
LDF kn = 0.0008
s−1. The experimental outside the bed (triangles)
breakthrough curve is shown for comparison. Predictions from the model (lines)
of the 2.5% location (circles), 50% location (squares), and 97.5% location
(diamonds) experimental center line temperature profile histories.
H2O on zeolite 5A (bottom panels): same as middle but now with LDF
kn adjusted to
kn = 0.0002
s−1 to match the slope of the experimental outside the bed
(triangles) breakthrough curve.
