Ceramic catalyst carriers form an important group of commonly used carrier materials in heterogeneous catalysis. They are primarily used in selective oxidation processes.
In heterogeneous catalysis bulk material catalysts are used to convert gaseous or liquid reactants. On an industrial scale fixed bed reactors are generally used for these types of reactions. The actual catalyst – i.e. the active catalytic substance – may be used alone or on a carrier. Carriers are used in situations where high demands are placed on the mechanical strength of the catalyst, the active catalytic substance must be present in a thin layer or there is a need to conserve valuable catalyst substances. A variety of materials are used to create catalyst carriers.
“Many intermediate and end products in the chemicals industry can only be produced with the help of catalysts.”
Catalyst Carriers Made from Ceramic Materials
- Dense catalyst carriers for shell type catalysts
- Porous catalyst carriers for impregnated catalysts
Ceramic catalyst carriers are an important group of carrier materials in heterogeneous catalysis and meet property requirements such as:
- Chemical inertness
- Mechanical strength and stability
- Low surface profile
- Bulk material uniformity
CeramTec supplies catalyst carriers made from steatite and porous alumina in a wide range of shapes and dimensions and can also custom tailor catalyst carriers to meet specific customer requirements.
