dc.description.abstract	Hydrotalcite (HT) was synthesized following combustion-recrystallization-impregnation procedure. The highest adsorption capacity observed was 1.21 mmol/g at operating temperature of 300°C and 0.4 bar of C02 partial pressure in the presence of N2. During adsorption-desorption study, it was shown that the removal and recovery of carbon dioxide at high temperature could be enhanced significantly in wet condition. This was further vindicated by the heat of adsorption that was higher in wet condition than dry condition. The breakthrough capacity measured at 300°C was the highest when the amount of water vapor was in the range of 25-27.5%, 27.5-30% and 30-32.5% (v/v) for carbon dioxide concentration in the feed maintained at 10%, 20% and 30% (v/v), respectively. Higher concentration of water vapor than these threshold amounts reduced the overall removal and recovery at all adsorbate concentration. The HT adsorbent could be reused for multiple times with relatively small loss of activity in wet condition. The measured loss of capacity was only 6.7% after 50 cycles of adsorption-desorption operation.	en_US
