What is alumina carriers?

Do you know what is alumina carriers? Or what do you know about the alumina carriers? Is it catalyst carriers?

What is alumina carriers? Zibo Xiangrun will explain in here. Catalyst carrier, also known as catalyst support, is one of composition of the supported catalyst. catalyst support is the material, usually a solid with a high surface area, to which a catalyst is affixed. Consequently, great effort is made to maximize the surface area of a catalyst by distributing it over the support. The support may be inert or participate in the catalytic reactions. Typical supports include various kinds of carbon, alumina, and silica.

Alumina carrier or alumina support as catalyst has  white alumina powder or solid alumina. Alumina support for catalyst is one of the most widely catalyst carrier, accounting for about 70% of the industry supported catalyst. Alumina support for catalyst has different shapes, like spheres, extrude, clover, ring and others.  The different forms of alumina carriers have different properties. Even if the shape of alumina carrier is same but because of different sources, there will be different properties, such as density, pore structure, specific surface area.

γ-Al2O3 is the starting point that determines the micro- and macrostructure of the oxide and, consequently, allows control of the support characteristics. The relevance of the adequate structural characterization of the oxide as well as of its surface sorption behavior through the proton-affinity distributions, are considered. The usefulness of the latter during supported catalyst preparation, for catalytic active sites characterization, and for stability evaluation after calcination are discussed for the Co/γ-Al2O3 system in particular.
