Abstract:
Some ionic liquids were investigated for abilities to capture CO2 alone or with added some catalysts at room temperature under atmospheric pressure to increase the capacity of ionic liquids to capture carbon dioxide gas some catalysts were found effective such asHydrated aluminum nitrate/urea ionic liquid with added CaO and NaOH , monoethanolamine and ammonium chloride were added to hydrated ammonium aluminum sulphate/urea ionic liquid did not show in FTIR sign of either physical or chemical absorption of CO2 . The addition of NaOHaq to hydrated ammonium aluminum sulphate/urea ionic liquid showed a new vibration absorption at 1666 cm - 1 and changing the frequencies in the amine group vibrational bands above 3000 cm - 1 . While the distilled water when added to the ionic liquid hydrated ammonium aluminum sulphate/urea showed a broaden effect on the high vibrational bands above 2500 cm - 1 and the carbonyl group vibrational band at 1662 cm - 1 was not effected .Calcium oxide was added to hydrated ammonium aluminum sulphate/urea showed a new splitting vibration absorption bands at 1666 cm - 1 ,1618 cm - 1 .Aluminum chloride - urea ionic liquid very effective to capture carbon dioxide gas without add any catalysts showed a chemical absorption of CO2 1655 cm - 1 while aluminum chloride - acetamide showed weaker or no ability to capture CO2 .
