Title:

METHOD FOR PROCESSING EXHAUST GAS OF CO2 COLLECTOR

Document Type and Number:

WIPO Patent Application WO/2011/016412

Kind Code:

A1

Abstract:

Disclosed is a method for highly efficiently removing amines, which are contained at low concentrations in an exhaust gas that is discharged from a CO2 collection process, at low temperatures. Specifically disclosed is a method for processing a carbon dioxide-containing exhaust gas, wherein an exhaust gas containing carbon dioxide (CO2) and nitrogen oxides is brought into contact with a CO2-absorbing liquid that contains amines, thereby absorbing and removing CO2 from the exhaust gas, and then the resulting exhaust gas is brought into contact with a catalyst that is composed of an oxide of titanium oxide and vanadium (V), or an oxide of titanium oxide and vanadium (V) and an oxide of molybdenum (Mo) or tungsten (W) at 130-250˚C, thereby oxidizing and removing the amines from the exhaust gas.
