<p>PURPOSE:To conveniently and efficiently denitrate an NOx-contg. gas by providing a treating vessel through which the gas is passed and arranging a zeolite with the layer of an azide compd. added with an acetate formed on its surface in the vessel. CONSTITUTION:A treating vessel 1 through which an NOx-contg. gas is passed is provided, and a zeolite 7 with the layer of an azide compd. added with an acetate formed on its surface is arranged in the vessel 1 to constitute the denitrator. In this case, a special synthetic zeolite is not used, an azide compd. is deposited on the zeolite 7, and NOx are removed by the zeolite 7. As a result, since a crystal is deposited on the zeolite 7 surface, the azide compd. carrying zeolite 7 having a uniform crystal layer is easily formed without using an adhesive, and the NOx are highly efficiently removed by the synergistic effect of the zeolite 7, azide compd. and acetate.</p> |
