摘要： One object is to provide an aldehyde decomposition catalyst, and an exhaust gas treatment apparatus and an exhaust gas treatment method using the aldehyde decomposition catalyst that achieve low cost and sufficient aldehyde decomposition performance with a small amount of the catalyst. An aldehyde decomposition catalyst of the present invention is made of a zeolite in a cation form NH4 having a structure selected from MFI and BEA and carrying at least one metal selected from the group consisting of Cu, Mn, Ce, Zn, Fe, and Zr.

摘要： Provided are a mercury oxidation catalyst support structure with which a mercury oxidation reaction can be carried out while inhibiting the oxidation reaction for SO2 included in exhaust gas and a method for manufacturing the same. This mercury oxidation catalyst structure is characterized by vanadium being unevenly supported on the surface of the support structure. The method for manufacturing the mercury oxidation catalyst structure includes a step of incorporating an inactive support throughout from the inside to the surface of the structure using an inactive support-containing liquid and a step of immersing the structure having been subjected to the step in a liquid containing vanadium or applying the same liquid to the surface of the same structure, followed by drying and calcinating, thereby supporting vanadium on the inactive support present in the surface of the structure.
