<p>Provided is a method capable of removing a low concentration of amines contained in an exhaust gas that is discharged from a CO 2 recovery process, at low temperature with high efficiency. A method of treating an exhaust gas containing carbon dioxide, the method including absorbing and removing CO 2 by bringing an exhaust gas containing carbon dioxide (CO 2 ) and nitrogen oxides, into contact with a CO 2 absorbent liquid containing amines, subsequently bringing the resultant into contact with a catalyst comprising titanium oxide and an oxide of vanadium (V), or from titanium oxide, an oxide of vanadium (V) and an oxide of molybdenum (Mo) or tungsten (W), at a temperature of 130°C to 250°C, and thereby oxidizing and removing the amines.</p> |
