Process for the detection of a product in the discharge of a catalytic material of a plurality of catalytic materials

摘要

Process for the detection of a product in the discharge of a catalytic material of a plurality of catalytic materials which are exposed to a reaction gas, whereby an adsorbent selective for the product to be determined is disposed in the discharge of each catalytic material, which changes at least one of its properties through the contact with the product to be determined and the change in the property of the adsorbent is then ascertained.The process serves in particular to determine the selectivity and activity of catalytic materials.
