Verfahren zur katalytischen Umsetzung eines Ausgangsstoffes, insbesondere eines Gasgemisches

摘要

The catalytic material is applied to a carrier material (10a,10b,10c) which is formed as a cell and/or channel having monolithic structure made of ceramic or metal. The increase of the reaction surface per volume unit is by reduction of hydraulic cross-section and/or reduction of material wall thickness of the channel structure to create an increased cell thickness of the catalytic material. In an apparatus for catalytic conversion of a starting material, the starting material is brought into contact with a catalytic material between one of inlets of the apparatus and outlet of the apparatus, and the active reaction surface of the catalytic material is step-wisely or continuously increased per volume unit from the inlet to the outlet of the apparatus by the entering starting material.
