제목 Regenerable hydrotalcite-based sorbents for CO2 captrue in pre-combustion process
초록 Hydrotalcite (HT)-based sorbents were prepared by the impregnation method with alkali metal. Their carbon dioxide (CO2) sorption properties were investigated in a typical fixed-bed reactor at intermediate temperature (200~400 °C) and high pressure (20 atm). The CO2 capture capacities of the HT-based sorbents showed about 8~9 wt% at 200 °C and 20 atm. Although the CO2 capture capacities of the HT-based sorbents were decreased during multiple cycles, those of sorbents were maintained after 2 cycle. In this study, we will discuss sorption properties and mechanism of the HT-based sorbents using XRD, BET, TG/DTA and TPD.
