Aluminum Oxide Powder used as Carrier
What is aluminum oxide provider?
Light weight aluminum oxide service provider describes white powder or shaped Light weight aluminum oxide solid, which is the most commonly used stimulant carrier, bookkeeping for about 70% of commercial sustained catalysts. Aluminum oxide has many kinds, not only various types have various residential or commercial properties, yet even the exact same kind has various residential properties due to its different sources, such as density, pore structure, specific surface area and so on.
These homes are of terrific value for light weight aluminum oxide made use of as driver carrier. Aluminum oxide is mainly prepared from its hydroxide (also known as Aluminum oxide hydrate or aluminum oxide hydrate).
Aluminum oxide service provider shapes.
Industrial aluminum oxide providers are powdered, however most of them are formed. Strip, round as well as ingot-shaped light weight aluminum oxide are primarily used as catalyst service providers in fixed-bed activators, while microspherical light weight aluminum oxide carriers are mainly utilized in fluidized bed reactors. It can also be made into special-shaped providers for certain catalytic processes, such as ring, trefoil, honeycomb, fiber (see light weight aluminum oxide fiber), etc. In addition to solids, light weight aluminum oxide sol is available for sale. The crucial specifications for choosing aluminum oxide are crystal form, pureness, specific surface, pore framework, bulk thickness and more. The specific area of α& alpha;- light weight aluminum oxide is very reduced( much less than 1m2/g), as well as the certain surface area of transition aluminum oxide is generally approximately 10 ~ 102m2/g.
Aluminum oxide service provider residential properties.
The majority of the developed industrial light weight aluminum oxide carriers are porous materials, and the pore dimension and also its distribution have a vital influence on the diffusion residential properties of catalysts in the stimulant bits in the catalytic process. The pore dimension of fine pores can be less than 20 μ & mu; m, while that of coarse pores can get to micron level. The pore framework differs with species. All transition light weight aluminum oxide has water more or less, as well as there are some hydroxyl groups as well as revealed light weight aluminum atoms externally, which reveals the qualities of B acid and also L acid (see acid-base driver), which has an important impact on the properties of Aluminum oxide service provider. The surface acidity is connected to the prep work conditions, particularly to the pollutant ions and also warmth treatment temperature level. Unfavorable ions such as halogen will certainly boost the surface acidity of light weight aluminum oxide, which will advertise the catalytic feature of light weight aluminum oxide itself for hydrocarbon cracking and isomerization.
Aluminum oxide powder applications.
Light weight aluminum oxide powder filled with catalytic energetic components. Aluminum oxide with small details area (or products with only a small number of coarse pores) is generally used to sustain catalyst active components with high details activity. The diffusion impact in pores can be eliminated by utilizing this sort of carrier, and also the deep oxidation side response can be lowered at the same time for the purpose of careful oxidation. For example, the silver driver for the oxidation of ethylene to ethylene oxide is supported by α& alpha;- aluminum oxide. Light weight aluminum oxide with large details surface has a strong pore framework, which can very distribute the energetic elements of the catalyst right into bits, and with the obstacle result of the provider, the active element bits can be prevented from sintering and maturing in the procedure of use. it is a kind of extensively utilized aluminum oxide provider. As an example, the rare-earth elements platinum, rhodium and more are distributed on light weight aluminum oxide support to make hydrogenation catalyst, which can enhance the application of rare-earth elements.
The surface area acidity of light weight aluminum oxide as well as the active elements loaded type bifunctional drivers. For instance, the platinum-aluminum oxide driver utilized in platinum reforming, in which aluminum oxide is not only a provider, but likewise among the active components of the driver.
