Catalyst module, receiving unit for such a catalyst module and method for manufacturing such a catalyst module

A catalyst module for use in an emission control system of an industrial scale combustion system comprising:

• a stack frame, extending in a longitudinal direction and in a transverse direction and having two end surfaces, located opposite to one another in a direction of flow,
• a plurality of mounting units, each having side walls, forming a peripheral side wall, inserted in the stack frame,
• the stack frame comprising a peripheral wall, formed from side frame parts, connected to one another via at least one mechanical connecting element and
• a sealing element pressed between at least one of the side frame parts and at least one mounting unit,
• where the mounting units are constructed as element boxes, which form an n×m matrix and adjoin one another and each of the element boxes forms the boundary of a free interior space, which is provided with several catalysts, which adjoin one another,
• where the element boxes are held together positively by complementary plug-in connection elements, and
• where at least one plug-in connection element as well as one plug-in opening is formed at the side walls.
