Abstract:
1. An apparatus for catalytic treatment of a gas flow comprising: a device having a catalyzer body that includes a catalytic material, the device further comprising a plurality of first openings for one of ( the catalyzer body defines an essentially cylindrical shape with an inner cavity that is open toward a second end of the body and the second opening forms part of the inner cavity; and the catalyzer body further has a zigzag-shaped structure that forms a plurality of ducts for gas throughflow and that are arranged so that every other one of the plurality of ducts in the zigzag structure is connected to at least one of the first openings and remainder of said plurality of ducts are connected to the second opening whereby gas flows in opposite directions in adjacent ducts thereby maintaining uniform temperature over the catalytic material.
