Capture of carbon dioxide gas from a flue gas mixture (N2:CO2 = 80:20) using amine-impregnated mesoporous sorbent (NETL-32D) was investigated in a small scale batch unit at ambient temperature and pressure. The variation of local bed temperature at different axial location of the bed, pressure drop across the bed, time to carbon breakthrough and adsorption capacity as a function of moisture content, bed heights and flow rates under both fixed bed and bubbling bed conditions was reported. Further, a time difference between the time to reach the peak bed pressure drop and temperature from the carbon breakthrough was established. The present findings are designed to offer a valuable data set for validation of CFD models studying carbon capture devices.
