Effects of calcination atmosphere and temperature on CO2 capture properties of MgO-based sorbents promoted with Na2CO3 and NaNO3 |
초록 |
To investigate effects of calcination atmosphere and temperature on CO2 capture properties of MgO sorbents, new MgO-based sorbents were prepared by impregnation of MgO with Na2CO3 (30 wt%) and NaNO3 (10 wt%). The CO2 capture capacities of the MgO-based sorbents were investigated in the fixed-bed reactor during multiple cycles at warm temperatures (capture at 300 ℃ and regeneration at 450 ℃). The CO2 capture capacities of the MgO-based sorbents calcined under nitrogen atmosphere were maintained about 90~100 mg CO2/g sorbent regardless of calcination temperature. However, the CO2 capture capacities of the MgO-based sorbents calcined under air atmosphere decreased with increasing calcination temperature. We will discuss characteristics and mechanism of MgO-based sorbents promoted with Na2CO3 and NaNO3 using XRD, TPD and TG in detail. |
