Abstract: A catalytic converter reactor having in-built catalytic converter modules, wherein the total flow impingement surface area provided by the catalytic converter elements fitted in the catalytic converter modules is larger than the flow impingement surface area of the catalytic converter reactor, the module impingement surface area being defined by the catalytic converter module surfaces facing the main flow direction, and the catalytic converter modules being positioned so that the waste gas flows through the catalytic converter elements contained therein in a direction different from the flow direction on the intake and exit sides.

Abstract: The invention relates to a catalyst module with internal fittings made of catalyst elements, wherein the surface area of the individual catalyst elements, against which flow is directed, is greater than the flow entry surface area of the catalyst module, wherein the surface of the module side facing the main direction of flow is defined as the module entry surface, and wherein the catalyst elements in the catalyst module are positioned such that flue gas glows through said elements in a direction differing from the entry side and/or the exit side direction of flow.
