Laboratory scale models were simulated with void fraction, ε and adsorbent loading, MF values as parameters to match the adsorption time and temperature rise for a set of pressure drops and lengths. The selected values of ε and MF were then used to simulate the laboratory scale models for all other combinations of pressure drop and length. This exercise resulted in an AAD of 14% for adsorption time, 41% for ΔT, and 13% for ΔTMax, indicating that maximum values of ΔT in tests correspond to the ideal adsorbent layer assumed in the models. From the qualitative temperature rise data and microscopic images of the PLOT columns, manufacturing variability and the absence of a continuous adsorbent layer were identified as the causes for the high value of AAD for ΔT. To minimize the AAD and improve model validation and model reliability, custom adsorbent-coated microchannels, for which information on adsorbent loading and adsorbent mass was available, were procured. Void fractions were precisely calculated for each of the samples tested. Batch adsorption tests were conducted on the custom channels and adsorption times and temperature rise values were noted. The simulations of laboratory scale models were conducted with the known values of ε and MF for the same experimental conditions. The comparison resulted in excellent agreement of the mass transfer data with the model results, with an AAD of 4%, and better agreement for ΔT, with AAD = 26%. There appears to be some manufacturing variability in these channels also; nevertheless, the agreement between the model results and the data is much better. The agreement between mass transfer data and model predictions suggest that for a given adsorbent mass, the adsorption time for the adsorbent-coated microchannel can be predicted. The ΔT values, despite being averaged for ten thermocouples, are dependent 161PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
