Catalyst shaped body for a flowing liquid or gaseous medium

摘要

The catalyst shaped body (F) is intended, in particular, for catalytic removal of nitrogen oxide (NOx) from an exhaust gas (G) by ammonia gas (NH3), e.g. in a power station. It has a plurality of adjoining part-bodies (A, B), the flow channels (p, q) of which pass into each other in a stepped manner. At the junctions (v) of the part-bodies (A, B), the part-stream of the medium of a flow channel (p) of the one part-body (A) is divided over a plurality of flow channels (q) of the other part-body (B). As a result of this diversion of the part-stream, turbulence is induced which leads to an improved exploitation of the catalytic activity of the interior walls. <IMAGE>
