Photograph of the TGC canister (a), and schematic longitudinal plane of the TGC canister (b). 1, aluminium canister container with electroless nickel plating; 2, 12 aluminium plates with electroless nickel plating connected to the canister container vertically and radially. Thermosensors were installed at eight sites (A, B, C1, D1, E1, C2, D2 and E2) in both the TGC canister and conventional canister to measure the temperature at each site. A and B are points at the canister inlet and outlet, respectively. C1, D1 and E1 are points 5 mm from the internal surface of the outer rim of the canister, with C1 being near the top of the CO2 absorbent, D1 near the middle and E1 near the bottom. C2, D2 and E2 are points 20 mm from the outer rim of the canister, corresponding in height to C1, D1 and E1, respectively.
