Production of Chemicals

Periodic System
In the chemical industry there is only a small number of reactions which are still realized without the addition of catalysts. Chemistry lives on and with the catalysis.
High activity and selectivity are the most important features.
The chemical and physical effects which can influence a catalyst are so varied that there can be no universal catalyst.
Good filterability and reusability of powder catalysts in liquid phase for batch reactions and mechanically stability and low pressure drop of shaped catalysts in fixed bed reactions are essential for the Heraeus high efficiency catalysts.
Beside our variety of standard catalysts we have access to a large range of support materials with very differing properties for the preparation of the optimum catalyst for the special requirements of the reaction. The network of our precious metal technologies including the production and development of precious metal compounds as well as the economical recycling of precious metals offer the complete service to our customers (all service – one stop).

The selection of the right carrier is important to create the optimized catalyst. Heraeus can offer a wide range of support material in different forms like powder, spheres, pellets, extrudates and granules.
