In the experimental set-up, the adsorbent-coated microchannel is laid between two fiberglass insulation sheets, which are coated with aluminum foil to reduce the radiation heat loss as shown in Figure 4.1(b). The heat transfer resistance network is shown in Figure 4.7. As CO2 is adsorbed into zeolite 5A in the adsorbent layer (shown in green in Figure 4.7), heat of adsorption is released. This heat is partially picked up by the adjoining gas stream in the microchannel (yellow region in Figure 4.7(b)), and 122PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
