• Catalyst development for many applications from the field of emission reduction (air pollutants such as carbon monoxide, unburned and partially burned hydrocarbons, and odorous substances).

• Material development takes place directly on the ceramic or metallic substrate (e.g. 1inch honeycomb). A later camouflage sfer on catalysts with larger cross sections can be realized without problems. The work thus also includes the development of suitable catalyst slurries.

• Development of coating specifications and catalyst slurries as well as service possible.

• Targeted development of dual layer catalysts or catalysts with defined zones for demanding applications. Possible for catalysts from 1" to 12 " diameter and 6" length.
• Design development is accompanied by theoretical studies, for which effective difussion coefficients are measured by means of a difussion measuring cell.

• Optical analysis is performed using cross-sectional images of catalysts embedded in resin via electron microscopy (including EDX) or laser microscopy.
• Analysis of catalysts even after chemical or mechanical poisoning is possible!

• Within the scope of research and service contracts, catalysts can be coated in metallic or ceramic form with many geometries.

• The coating is made from catalyst lurys via classical impregnation processes or wetting processes.

• Another innovative process is the coating of catalyst shaped bodies by means of flame spray pyrolysis. Here, not only water-soluble catalyst components are suitable for coating. Conventional catalyst slurries can be uniformly deposited on the molded bodies via the flame passage. In the current configurations, catalysts with a diameter of 3" and a length of 2" can be coated.

• Thanks to the development of our own coating processes, it is possible to coat inexpensive textiles such as PET with catalytically active materials that are permanently immobilized on the textiles.

• The development of catalytically active coatings is also possible. These materials are tested for their properties as catalysts and as coatings, as can be seen from the scratch test.
