摘要： PROBLEM TO BE SOLVED: To provide a practical, highly active decomposition catalyst capable of removing NOx, especially, NO contained in exhaust gases originated from all combustion apparatus by directly decomposing them at a high temp. without reducing agents, and to provide the practical method for removing nitrogen oxides using the catalyst for treating the exhaust gas containing oxygen and steam. SOLUTION: The decomposition catalyst containing, as a catalytically active component, at least one metal complex oxide of the composition formula AB1-x Ex/2 Px/2 O3+-z , (A is an alkaline earth metal; B is an metal of the titanium group elements; E is a metal selected from vanadium group elements, P is each one metal selected from the copper group or platinum group elements), preferably, whose crystalline structure is a perovskite-type, is used for removing nitrogen oxides. As this catalyst has a high resistance against the poisoning caused by steam, the nitrogen oxides in the exhaust gas containing steam can be removed by directly bringing the exhaust gas into contact with the catalyst at 600-1,000 deg.C, in the presence of or in the absence of oxygen without removing moisture from and drying the gas and without adding reducing agents.

摘要： PROBLEM TO BE SOLVED: To provide a hydrogen producing apparatus where leaked carbon monoxide is as little as possible even when defects are caused in a hydrogen separating layer. SOLUTION: In the hydrogen producing apparatus where a raw material gas is reformed and hydrogen is generated, the raw material gas is reformed in a reforming catalyst layer 50 and hydrogen is generated, permeated selectively in the hydrogen separating layer 30 and then separated. Carbon monoxide in gases except hydrogen permeated through the hydrogen separating layer 30 is converted to a hydrocarbon gas in a converting catalyst layer 10. A second porous reaction preventing layer 20 and a first porous reaction preventing layer 40 preventing reactions between the component of the hydrogen separating layer 30 and catalytic components in respective layers are arranged between the reforming catalyst layer 50 and the hydrogen separating layer 30 and between the hydrogen separating layer 30 and the converting catalyst layer 10. In this way, the amount of the leaked carbon monoxide is minimized by the methanation of carbon monoxide in the converting catalyst layer 10 even if the defects are caused in the hydrogen separating layer 30.
