What is Catalyst Carrier

What is Catalyst Carrier


A catalyst carrier (support) is a low-activity or inert material, which serves to stabilize the particles of the catalytic active phase on its surface.

The catalyst carrier can be used in the form of natural (various clays, asbestos, pumice, diatomite) or synthetic materials (oxides of aluminium, zirconium or magnesium, silica gel, activated carbons, aluminosilicates).

Functions of Catalyst Carriers

The function of carriers in heterogenous catalysis is to prevent the sintering or agglomeration of the active component to maintain the required area of contact between the agents and the active substance. The amount of the catalyst carrier is generally greater than the amount of the primary active component applied onto it.

The principal requirements for catalyst carriers include a large surface area, thermal stability, porosity, chemical inertness and increased mechanical strength. In some cases, catalyst carriers affect the active phase performance, that is the effect of a strong interaction between the metal and the carrier is observed.

The FNG water resistant silica gel and wide pore silica gel produced by YIMING Silica Gel Factory are widely used in the field of catalyst and catalyst carrier, with professional production technology and advanced production equipment.
