Ceramic catalyst carriers are an important component of heterogeneous catalysis. They are primarily used in highly selective oxidation processes. In heterogeneous catalysis, bulk material catalysts are used in the chemicals industry to convert gaseous or liquid reactants.
The actual catalyst, the catalytic substance, may be used as a mold alone or with a carrier. Carriers are necessary 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.
CeramTec works together with the customer to develop the specifically required mold and then offers catalyst carriers in lab quantities up to large-scale production.
A wide variety of materials offered by CeramTec can be used for catalyst carriers.
Dense catalyst carriers (for shell type catalysts)
Porous catalyst carriers (for impregnated catalysts)
The porosity can be adjusted to the respective customer needs for the required surface, e.g. it can range from simple porosity to a special bi-modal and tri-modal pore distribution.
