Title:

METHOD FOR ADSORBING AND DECOMPOSING LEAN NITROGEN OXIDE USING A MIXED METAL OXIDE CATALYST

Document Type and Number:

WIPO Patent Application WO/2011/052920

Kind Code:

A2

Abstract:

The present invention relates to a method for adsorbing and reducing lean nitrogen oxide using a mixed metal oxide catalyst. In detail, the method of the present invention improves nitrogen oxide adsorbing, storing, and desorbing performance using a mixed metal oxide catalyst produced from hydrotalcite-type precursors. In the event oxygen exists together with NOx and N2O, thus rendering a reduction and decomposition process significantly difficult, the method of the present invention involves separating NOx and N2O from said oxygen, adsorbing the NOx and N2O, and decomposing and desorbing the NOx and N2O using a reducing agent in an easy manner, thereby improving the efficiency of decomposition.
