Aluminum Oxide Powder used as Carrier

What is light weight aluminum oxide carrier? Light weight aluminum oxide service provider describes white powder or molded Light weight aluminum oxide strong, which is the most extensively made use of stimulant service provider, accounting for around 70% of commercial supported drivers. Aluminum oxide has many forms, not only different forms have different properties, yet even the exact same kind has different residential or commercial properties as a result of its various sources, such as density, pore framework, details area and more.

These buildings are of wonderful relevance for aluminum oxide made use of as catalyst provider. Light weight aluminum oxide is mostly prepared from its hydroxide (likewise known as Aluminum oxide hydrate or aluminum oxide hydrate).
. Aluminum oxide provider shapes. Industrial light weight aluminum oxide service providers are powdered, yet a lot of them are formed. Strip, spherical as well as ingot-shaped aluminum oxide are mostly made use of as stimulant service providers in fixed-bed activators, while microspherical light weight aluminum oxide carriers are primarily utilized in fluidized bed reactors. It can additionally be made into special-shaped carriers for details catalytic procedures, such as ring, trefoil, honeycomb, fiber (see light weight aluminum oxide fiber), and so on. In addition to solids, light weight aluminum oxide sol is offered up for sale. The important parameters for choosing aluminum oxide are crystal form, pureness, certain surface, pore framework, mass density and so forth. The certain surface of α& alpha;- light weight aluminum oxide is very low( much less than 1m2/g), and also the details surface of transition aluminum oxide is normally up to 10 ~ 102m2/g.
. Light weight aluminum oxide service provider residential or commercial properties. Most of the created industrial aluminum oxide providers are porous materials, and also the pore size and its distribution have an essential impact on the diffusion properties of reactants 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 rugged pores can reach micron degree. The pore structure varies with types. All change aluminum oxide includes water more or less, and there are some hydroxyl groups as well as subjected light weight aluminum atoms on the surface, which reveals the attributes of B acid and L acid (see acid-base driver), which has a vital impact on the buildings of Light weight aluminum oxide provider. The surface area acidity is associated with the prep work problems, specifically to the pollutant ions and warmth treatment temperature. Adverse ions such as halogen will certainly boost the surface level of acidity of aluminum oxide, which will advertise the catalytic feature of aluminum oxide itself for hydrocarbon cracking as well as isomerization.
. Aluminum oxide powder applications. Light weight aluminum oxide powder filled with catalytic energetic parts. Aluminum oxide with small details surface (or materials with just a handful of rugged pores) is normally used to sustain stimulant energetic parts with high specific activity. The diffusion impact in pores can be removed by utilizing this kind of provider, and also the deep oxidation side reaction can be lowered in the process for the objective of selective oxidation. For instance, the silver driver for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- light weight aluminum oxide. Aluminum oxide with big details surface area has a well-developed pore framework, which can very disperse the active elements of the stimulant right into fragments, and also with the barrier impact of the provider, the active element particles can be protected against from sintering and growing up in the process of use. it is a kind of commonly utilized aluminum oxide provider. As an example, the precious metals platinum, rhodium and so forth are distributed on light weight aluminum oxide assistance to make hydrogenation driver, which can boost the application of precious metals.

The surface area acidity of light weight aluminum oxide and also the active elements packed type bifunctional catalysts. For example, the platinum-aluminum oxide driver utilized in platinum changing, in which aluminum oxide is not just a service provider, but additionally one of the active parts of the stimulant.
