    • PROBLEM TO BE SOLVED: To provide a method for producing a catalyst structure for a flue gas desulfurization apparatus capable of improving strength of an object to be supported of the catalyst structure and improving durability.SOLUTION: A method for producing a catalyst structure body for a flue gas desulfurization apparatus is a method for producing a honeycomb catalyst structure 10 used for a flue gas desulfurization apparatus for recovering sulfur oxides contained in exhaust gas as a sulfuric acid. The integral block honeycomb catalyst structure 10 having a large number of channel spaces extending in the vertical direction and having the opened upper end and lower end is produced by sticking or welding to laminate activated carbon-based desulfurization catalyst sheets 20 (20A, 20B). The lower end part of the honeycomb catalyst structure 10 is installed by being supported by supporting parts 31Ca and 31Cb. The laminated desulfurization catalyst sheets 20 are bonded in the upper region of a supported part of the honeycomb catalyst structure 10 supported by at least the supporting part 31Ca in both side end parts.
    • 要解决的问题:提供一种能够提高催化剂结构负载物的强度并提高耐久性的烟道气脱硫装置的催化剂结构体的制造方法。本发明提供一种催化剂结构体的制造方法, 烟道气脱硫装置是用于回收废气中所含的硫氧化物作为硫酸的烟道气脱硫装置的蜂窝催化剂结构体10的制造方法。 通过粘贴或焊接将活性碳系脱硫催化剂片20(20A,20B)层叠,制造具有沿垂直方向延伸的多个通道空间并具有开口的上端和下端的一体式嵌段蜂窝催化剂结构体10。 蜂窝状催化剂结构体10的下端部被支承部31Ca,31Cb支承。 叠层式脱硫催化剂片20在由两个侧端部至少由支撑部31Ca支撑的蜂窝催化剂结构体10的支承部的上部区域接合。
