As a technique for removing hydrogen, an ammonia catalytic reduction method in which ammonia is injected as a reducing agent and NOx is catalytically reduced to N 2 is mainly adopted and put into practical use. Since the exhaust gas to be treated contains dust, the structure of the structure (hereinafter referred to as "catalyst body") having a flow hole for the exhaust gas in one direction and formed of a catalyst material has a cross section. The honeycomb type (hereinafter referred to as "honeycomb catalyst") or the plate type is mainly used.

スの気密性を図っている。Among the above, the honeycomb catalyst is limited in size of a single molded body in manufacturing. Therefore, when a large reaction volume is required as in a catalyst body such as flue gas, a single honeycomb body is used. It is necessary to arrange a large number of catalysts so that the gas flow holes are parallel to each other, and further to vertically stack the gas flow holes so as to improve the catalyst efficiency. For that purpose, it is effective to incorporate a plurality of stacked single honeycomb catalysts as one unit (hereinafter referred to as “unit”) (unitization), and a plurality of stacked units. Moreover, it is necessary to form blocks such as those in which units are arranged in series in the gas flow holes. Related to this, for example, Japanese Patent Publication No. 53-137866,
Japanese Patent Publication No. 53-26265 and the like disclose that adjacent honeycomb catalysts are adhered to each other by an adhesive so as to be integrated, or a cushioning material is provided between the honeycomb catalysts. Further, a cushioning material is interposed between the honeycomb catalysts, between the units, and in the gaps between the blocks and the frame around the blocks to fix the honeycomb catalysts to prevent the honeycomb catalysts from being damaged and to ensure gas tightness between the honeycomb catalysts. ing.
