Aluminum Oxide Powder used as Carrier

What is light weight aluminum oxide service provider? Light weight aluminum oxide provider refers to white powder or molded Aluminum oxide strong, which is one of the most commonly utilized catalyst carrier, accountancy for about 70% of commercial sustained catalysts. Light weight aluminum oxide has many types, not only different types have various buildings, however even the exact same type has various residential properties because of its various resources, such as thickness, pore structure, certain surface and so forth.

These properties are of wonderful value for light weight aluminum oxide utilized as stimulant provider. Aluminum oxide is primarily prepared from its hydroxide (also known as Light weight aluminum oxide hydrate or aluminum oxide hydrate).
. Light weight aluminum oxide service provider shapes. Commercial aluminum oxide providers are powdered, but a lot of them are formed. Strip, round as well as ingot-shaped light weight aluminum oxide are mostly used as stimulant carriers in fixed-bed reactors, while microspherical aluminum oxide carriers are primarily used in fluidized bed activators. It can also be made into special-shaped carriers for particular catalytic processes, such as ring, trefoil, honeycomb, fiber (see aluminum oxide fiber), and so on. Along with solids, light weight aluminum oxide sol is readily available for sale. The important criteria for selecting light weight aluminum oxide are crystal form, pureness, certain surface, pore structure, bulk density and so on. The particular surface of α& alpha;- light weight aluminum oxide is really reduced( much less than 1m2/g), and the certain area of shift light weight aluminum oxide is usually as much as 10 ~ 102m2/g.
. Light weight aluminum oxide service provider residential properties. A lot of the developed commercial aluminum oxide carriers are permeable materials, and also the pore dimension as well as its circulation have a crucial influence on the diffusion properties of catalysts in the catalyst particles in the catalytic process. The pore size of great pores can be less than 20 μ & mu; m, while that of crude pores can get to micron level. The pore framework differs with species. All shift light weight aluminum oxide has water basically, and there are some hydroxyl groups and also revealed light weight aluminum atoms on the surface, which shows the qualities of B acid as well as L acid (see acid-base catalyst), which has an important influence on the residential or commercial properties of Aluminum oxide carrier. The surface area level of acidity is associated with the preparation conditions, particularly to the pollutant ions as well as warm therapy temperature level. Unfavorable ions such as halogen will certainly boost the surface level of acidity of light weight aluminum oxide, which will promote the catalytic function of aluminum oxide itself for hydrocarbon splitting and isomerization.
. Light weight aluminum oxide powder applications. Light weight aluminum oxide powder loaded with catalytic energetic parts. Aluminum oxide with little particular surface area (or materials with just a handful of crude pores) is generally used to sustain driver energetic components with high particular task. The diffusion result in pores can be eliminated by utilizing this sort of provider, and also the deep oxidation side reaction can be decreased in the process for the function of selective oxidation. As an example, the silver driver for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- aluminum oxide. Light weight aluminum oxide with big certain surface area has a strong pore structure, which can highly spread the active parts of the driver into fragments, as well as with the obstacle effect of the provider, the active element bits can be avoided from sintering and also maturing in the procedure of usage. it is a kind of extensively utilized light weight aluminum oxide service provider. For instance, the rare-earth elements platinum, rhodium and more are dispersed on light weight aluminum oxide assistance to make hydrogenation driver, which can improve the application of precious metals.

The surface acidity of aluminum oxide and the active elements loaded type bifunctional stimulants. As an example, the platinum-aluminum oxide driver used in platinum changing, in which light weight aluminum oxide is not only a carrier, but likewise one of the energetic parts of the driver.
. Light weight aluminum oxide Powder Rate. The rate is influenced by many factors including the supply and also need in the market, market patterns, financial task, market belief, and also unanticipated events.
