What is catalyst support?

Catalyst carrier also known as the carrier (support), is one of the components of the supported catalyst. The catalytically active component is carried on the surface of the support, the support being mainly used for supporting the active component so that the catalyst has specific physical properties, and the support itself is generally not catalytically active. Most carriers are products in the catalyst industry. Commonly used are alumina carriers, silica carriers, activated carbon carriers and some natural products such as pumice, diatomaceous earth and the like. The “active ingredient name-carrier name” is often used to indicate the composition of supported catalysts such as nickel-alumina catalysts for hydrogenation, vanadia-diatomaceous earth catalysts for oxidation.

 

Kind of catalyst carrier or catalyst support

The catalyst carriers studied more at home and abroad include: SiO2, Al2O3, glass fiber mesh (cloth), hollow ceramic balls, sea sand, layered graphite, hollow glass beads, quartz glass tubes, Plexiglass, optical fiber, natural clay, foam, resin, wood chips, expanded perlite, activated carbon and so on.
