Aluminum Oxide Powder used as Carrier

What is aluminum oxide service provider? Aluminum oxide service provider describes white powder or shaped Light weight aluminum oxide strong, which is one of the most commonly made use of driver service provider, accounting for about 70% of industrial sustained drivers. Light weight aluminum oxide has many forms, not just various types have different properties, but also the same kind has various properties because of its various resources, such as thickness, pore structure, particular area and so on.

These homes are of great relevance for light weight aluminum oxide utilized as catalyst carrier. Light weight aluminum oxide is mostly prepared from its hydroxide (additionally known as Aluminum oxide hydrate or aluminum oxide hydrate).
. Light weight aluminum oxide service provider forms. Business aluminum oxide service providers are powdered, however the majority of them are formed. Strip, spherical and ingot-shaped aluminum oxide are primarily used as stimulant service providers in fixed-bed reactors, while microspherical light weight aluminum oxide providers are mostly utilized in fluidized bed reactors. It can likewise be made right into special-shaped carriers for details catalytic procedures, such as ring, trefoil, honeycomb, fiber (see aluminum oxide fiber), and so on. Along with solids, aluminum oxide sol is available up for sale. The essential parameters for selecting light weight aluminum oxide are crystal form, pureness, particular surface area, pore framework, mass thickness and more. The certain surface of α& alpha;- aluminum oxide is very low( less than 1m2/g), as well as the specific surface area of change aluminum oxide is typically approximately 10 ~ 102m2/g.
. Light weight aluminum oxide provider properties. Most of the formed industrial light weight aluminum oxide providers are porous materials, and also the pore dimension and its distribution have an essential influence on the diffusion buildings of reactants in the driver bits in the catalytic procedure. The pore dimension of fine pores can be much less than 20 μ & mu; m, while that of crude pores can reach micron level. The pore framework varies with types. All shift aluminum oxide has water more or less, as well as there are some hydroxyl teams as well as revealed light weight aluminum atoms externally, which shows the qualities of B acid as well as L acid (see acid-base driver), which has an essential influence on the properties of Aluminum oxide carrier. The surface area level of acidity is related to the preparation problems, particularly to the contamination ions and also warm treatment temperature. Unfavorable ions such as halogen will boost the surface level of acidity of light weight aluminum oxide, which will advertise the catalytic feature of light weight aluminum oxide itself for hydrocarbon breaking and also isomerization.
. Light weight aluminum oxide powder applications. Aluminum oxide powder packed with catalytic energetic parts. Light weight aluminum oxide with tiny specific surface area (or materials with just a small number of rugged pores) is generally made use of to support catalyst active components with high certain activity. The diffusion effect in pores can be eliminated by using this sort of service provider, and also the deep oxidation side response can be reduced while doing so for the function of careful oxidation. For instance, the silver driver for the oxidation of ethylene to ethylene oxide is supported by α& alpha;- light weight aluminum oxide. Aluminum oxide with huge specific surface has a strong pore framework, which can very disperse the active parts of the catalyst into bits, as well as with the barrier result of the service provider, the active element fragments can be prevented from sintering and growing up in the process of usage. it is a type of widely utilized light weight aluminum oxide service provider. For example, the precious metals platinum, rhodium and more are distributed on aluminum oxide assistance to make hydrogenation driver, which can improve the use of rare-earth elements.

The surface area acidity of light weight aluminum oxide and the active parts crammed type bifunctional stimulants. As an example, the platinum-aluminum oxide catalyst made use of in platinum reforming, in which aluminum oxide is not only a carrier, yet additionally among the energetic elements of the stimulant.
