Precious Metal Powder Catalysts are heterogeneous catalysts for slurry type reactions that are carried out in batch or semi-batch mode. They are widely used in the fine chemicals and the pharmaceutical industry, though there are other applications.

• Powdered, heterogeneous catalyst
• Catalysts for slurry phase reactions
• Precious metal fixed on a support
• Highly dispersed, stable metal crystallites

Portfolio
Our portfolio of precious metal powder catalysts is very broad and ranges from Pd/C to multi-metallic catalysts on carbon black. Important to know is that by variations in the recipe and the raw materials precious metal powder catalysts can be fine tuned for their application. For more details on the product properties and their application please download our brochure, or visit the Catalyst Guide.
