What is light weight aluminum oxide carrier?
Light weight aluminum oxide service provider describes white powder or shaped Aluminum oxide strong, which is the most commonly utilized catalyst carrier, accounting for about 70% of industrial sustained drivers. Aluminum oxide has numerous types, not just different kinds have different residential properties, but also the very same form has various buildings due to its various resources, such as density, pore framework, specific surface and more.
These residential properties are of wonderful value for light weight aluminum oxide used as driver provider. Light weight aluminum oxide is mostly prepared from its hydroxide (additionally called Aluminum oxide hydrate or aluminum oxide hydrate).
Aluminum oxide provider forms.
Industrial aluminum oxide service providers are powdered, yet most of them are built. Strip, round and ingot-shaped aluminum oxide are primarily utilized as stimulant providers in fixed-bed activators, while microspherical light weight aluminum oxide service providers are primarily made use of in fluidized bed activators. It can likewise be made into special-shaped service providers for certain catalytic procedures, such as ring, trefoil, honeycomb, fiber (see aluminum oxide fiber), and so on. In addition to solids, aluminum oxide sol is available for sale. The essential criteria for picking aluminum oxide are crystal form, pureness, details area, pore framework, bulk density and so on. The certain surface area of α& alpha;- light weight aluminum oxide is really reduced( much less than 1m2/g), and the particular area of shift aluminum oxide is normally approximately 10 ~ 102m2/g.
Light weight aluminum oxide provider properties.
Most of the developed industrial light weight aluminum oxide carriers are porous materials, and the pore size and also its circulation have a crucial influence on the diffusion properties of reactants in the stimulant fragments in the catalytic process. The pore dimension of great pores can be less than 20 μ & mu; m, while that of crude pores can reach micron level. The pore framework varies with types. All shift light weight aluminum oxide has water more or less, and also there are some hydroxyl groups as well as exposed aluminum atoms externally, which reveals the attributes of B acid and also L acid (see acid-base driver), which has a vital impact on the residential properties of Light weight aluminum oxide carrier. The surface acidity is associated with the preparation problems, particularly to the contamination ions and also heat treatment temperature level. Negative ions such as halogen will boost the surface area acidity of aluminum oxide, which will certainly promote the catalytic function of aluminum oxide itself for hydrocarbon fracturing and isomerization.
Light weight aluminum oxide powder applications.
Aluminum oxide powder packed with catalytic active components. Aluminum oxide with small certain surface (or materials with only a handful of rugged pores) is typically used to support driver active components with high specific task. The diffusion result in pores can be eliminated by using this kind of carrier, and also the deep oxidation side response can be minimized while doing so for the purpose of selective oxidation. For instance, the silver stimulant for the oxidation of ethylene to ethylene oxide is supported by α& alpha;- light weight aluminum oxide. Aluminum oxide with big particular surface area has a well-developed pore framework, which can highly disperse the energetic components of the stimulant into particles, as well as with the barrier effect of the carrier, the active component fragments can be stopped from sintering and also growing up in the procedure of usage. it is a type of commonly utilized light weight aluminum oxide carrier. As an example, the rare-earth elements platinum, rhodium and so on are dispersed on light weight aluminum oxide assistance to make hydrogenation catalyst, which can boost the usage of rare-earth elements.
The surface area level of acidity of aluminum oxide and the active elements loaded kind bifunctional catalysts. For instance, the platinum-aluminum oxide stimulant made use of in platinum changing, in which light weight aluminum oxide is not only a service provider, however also one of the energetic components of the catalyst.
