Catalyst Carriers

Tailormade catalyst carriers

Choosing the right carrier is crucial for an effective and consistent catalysis. Evonik provides a wide choice of inorganic oxides with a high specific surface area, covering different requirements of catalyst producers. AEROSIL® fumed silica, SIPERNAT® precipitated silica and AEROXIDE® fumed metal oxides are long-established components of catalyst formulations. With their porous structure and their surface, carrier silicas and metal oxides absorb catalytically active metal particles and distribute them homogeneously in formed catalysts used in fixed, trickle bed or stirred-tank reactors.

Customers have the choice of a variety of fumed and precipitated silica with variable specific surface area and controlled mesoporosity. Additionally, fumed titania and alumina products with high purity and specific surface area are made available for more demanding applications.
