Aluminum Oxide Powder used as Carrier

What is light weight aluminum oxide carrier? Aluminum oxide carrier describes white powder or shaped Light weight aluminum oxide strong, which is the most widely used stimulant carrier, accounting for around 70% of commercial sustained stimulants. Aluminum oxide has several forms, not only different forms have different properties, yet even the same type has various homes due to its different sources, such as density, pore framework, particular area and so on.

These homes are of wonderful value for light weight aluminum oxide utilized as catalyst provider. Aluminum oxide is mainly prepared from its hydroxide (additionally referred to as Light weight aluminum oxide hydrate or aluminum oxide hydrate).
. Light weight aluminum oxide provider shapes. Industrial aluminum oxide service providers are powdered, but most of them are built. Strip, round and ingot-shaped light weight aluminum oxide are mainly utilized as catalyst service providers in fixed-bed reactors, while microspherical aluminum oxide providers are mainly utilized in fluidized bed reactors. It can additionally be made into special-shaped service 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 offered for sale. The crucial parameters for selecting aluminum oxide are crystal kind, pureness, particular surface area, pore structure, mass thickness and so on. The specific surface of α& alpha;- aluminum oxide is very reduced( less than 1m2/g), and the specific surface of transition light weight aluminum oxide is normally as much as 10 ~ 102m2/g.
. Light weight aluminum oxide service provider residential properties. Most of the developed industrial light weight aluminum oxide carriers are permeable materials, as well as the pore dimension and also its distribution have a vital impact on the diffusion residential properties of catalysts in the driver bits in the catalytic procedure. The pore dimension of great pores can be less than 20 μ & mu; m, while that of crude pores can reach micron degree. The pore framework differs with varieties. All shift aluminum oxide has water essentially, as well as there are some hydroxyl groups and also subjected aluminum atoms on the surface, which shows the characteristics of B acid and L acid (see acid-base stimulant), which has an important impact on the residential or commercial properties of Light weight aluminum oxide provider. The surface area level of acidity is related to the preparation conditions, especially to the contamination ions and also warmth therapy temperature level. Adverse ions such as halogen will boost the surface area acidity of aluminum oxide, which will advertise the catalytic function of light weight aluminum oxide itself for hydrocarbon splitting and also isomerization.
. Light weight aluminum oxide powder applications. Light weight aluminum oxide powder packed with catalytic active components. Light weight aluminum oxide with little certain area (or materials with just a small number of rugged pores) is normally utilized to support stimulant active parts with high particular task. The diffusion result in pores can be eliminated by utilizing this kind of provider, and the deep oxidation side reaction can be lowered in the process for the function of discerning oxidation. As an example, the silver catalyst for the oxidation of ethylene to ethylene oxide is supported by α& alpha;- light weight aluminum oxide. Light weight aluminum oxide with large certain surface has a strong pore framework, which can very distribute the energetic parts of the catalyst right into fragments, as well as with the obstacle impact of the carrier, the active element fragments can be protected against from sintering as well as maturing in the procedure of usage. it is a type of widely utilized light weight aluminum oxide carrier. For instance, the precious metals platinum, rhodium and so on are dispersed on aluminum oxide assistance to make hydrogenation catalyst, which can boost the usage of rare-earth elements.

The surface level of acidity of aluminum oxide as well as the active parts loaded kind bifunctional stimulants. For instance, the platinum-aluminum oxide catalyst utilized in platinum reforming, in which light weight aluminum oxide is not only a provider, yet also one of the active elements of the driver.
. Light weight aluminum oxide Powder Rate. The cost is influenced by many elements consisting of the supply as well as need out there, market patterns, economic task, market view, and unanticipated events.
