Aluminum Oxide Powder used as Carrier
What is light weight aluminum oxide service provider?
Light weight aluminum oxide carrier refers to white powder or shaped Aluminum oxide strong, which is the most commonly utilized catalyst service provider, accounting for around 70% of commercial sustained drivers. Aluminum oxide has several types, not just various types have different residential properties, but also the exact same type has various residential properties because of its various sources, such as density, pore framework, specific surface area and so forth.
These residential properties are of wonderful value for light weight aluminum oxide made use of as driver service provider. Light weight aluminum oxide is mainly prepared from its hydroxide (additionally called Aluminum oxide hydrate or light weight aluminum oxide hydrate).

Light weight aluminum oxide carrier shapes.
Commercial light weight aluminum oxide service providers are powdered, however a lot of them are molded. Strip, spherical and ingot-shaped aluminum oxide are mainly used as stimulant service providers in fixed-bed activators, while microspherical light weight aluminum oxide service providers are mostly made use of in fluidized bed activators. It can also be made into special-shaped service providers for specific catalytic processes, such as ring, trefoil, honeycomb, fiber (see light weight aluminum oxide fiber), etc. Along with solids, light weight aluminum oxide sol is available for sale. The crucial criteria for selecting light weight aluminum oxide are crystal form, purity, specific area, pore structure, bulk thickness and so on. The details surface area of α& alpha;- aluminum oxide is extremely low( much less than 1m2/g), and the details area of shift light weight aluminum oxide is normally approximately 10 ~ 102m2/g.

Aluminum oxide carrier residential properties.
Most of the created industrial aluminum oxide providers are permeable materials, and the pore size and its circulation have a vital influence on the diffusion buildings of catalysts in the stimulant bits in the catalytic procedure. The pore dimension of great pores can be less than 20 μ & mu; m, while that of coarse pores can reach micron level. The pore structure differs with varieties. All change light weight aluminum oxide consists of water essentially, and there are some hydroxyl groups and also exposed aluminum atoms externally, which reveals the features of B acid and L acid (see acid-base stimulant), which has a crucial impact on the residential properties of Light weight aluminum oxide provider. The surface acidity is associated with the preparation conditions, especially to the impurity ions as well as heat therapy temperature level. Unfavorable ions such as halogen will certainly enhance the surface area level of acidity of aluminum oxide, which will promote the catalytic feature of aluminum oxide itself for hydrocarbon fracturing and also isomerization.

Aluminum oxide powder applications.
Aluminum oxide powder filled with catalytic active components. Aluminum oxide with little certain surface area (or products with just a small number of rugged pores) is usually used to sustain driver energetic components with high details task. The diffusion effect in pores can be eliminated by using this sort of carrier, and also the deep oxidation side reaction can be lowered at the same time for the objective of selective oxidation. For instance, the silver stimulant for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- light weight aluminum oxide. Light weight aluminum oxide with huge details surface has a strong pore framework, which can very distribute the active components of the stimulant right into particles, and also with the obstacle effect of the carrier, the energetic component bits can be protected against from sintering as well as growing up in the procedure of use. it is a kind of commonly used light weight aluminum oxide carrier. For instance, the rare-earth elements platinum, rhodium and so forth are distributed on light weight aluminum oxide assistance to make hydrogenation catalyst, which can boost the use of rare-earth elements.
The surface area acidity of light weight aluminum oxide and also the active elements packed type bifunctional stimulants. For instance, the platinum-aluminum oxide catalyst utilized in platinum changing, in which aluminum oxide is not just a service provider, yet additionally one of the energetic elements of the stimulant.
