WebOct 13, 2015 · Munakata et al. ( 2003, 2008) investigated the adsorption of krypton on various adsorbents including silver-modernite. They concluded that Ag-modernite have large capacity of Kr adsorption at 273 K but carbon-based adsorbents were found to be more active than Ag-modenite at cryogenic temperatures.

WebJul 15, 2024 · Adsorption experiments were performed to determine the capacity of 10 wt% C@ETS-10 sorbent for iodine and krypton in multicomponent mixture system by varying operating parameters, such as inlet concentration of iodine (I 2) and krypton (Kr), and adsorption column temperature. WebDuring the experiment, the acquisition time for a single scan was 160 s with a voxel size of 2 μm. The oil shale sample was pyrolyzed in a nitrogen environment from 20 °C to 500 °C with the temperature that was held constant at key pyrolysis stages where scans were recorded ( Fig. 9 (a)), which produced dynamic imaging with a total of 52 scans. in and out onion
