dc.description.abstract	Hydrotalcite-like compounds {HT) were synthesized following a combustion-reccystallization-impregnation procedure using aluminum, magnesium nitrates precursors and carbonate solutions. Different types and amount of fuels, different amount of carbonate and different synthesis temperature were used during HT synthesis in order to understand their roles in forming HT structure and C02 adsorption level. It was discovered that the addition of fuels to facilitate the reaction into mixed oxides and later HT influenced the capacity of C02 adsorption. Beside type and amount of fuels, the carbonate amount and synthesis temperature also played important roles in forming the HT structure and thus, the C02 adsorption level. The highest adsorption capacity was observed at 1.21 mmol/g by K-Na HT (K of18.5% and Na of 1.5%) at operating temperature of 300 oc and 0.4 bar of C02 partial pressure in the presence of N2 (equivalent to total pressure of 1.34 bar). The HT exhibited Type IV isotherm, a typical mesoporous and slit shape pore material with pore size of 5.4 A and BET surface area of 124m2/g.	en_US
