Aluminum Oxide Powder used as Carrier
What is light weight aluminum oxide provider?
Light weight aluminum oxide provider refers to white powder or shaped Aluminum oxide strong, which is one of the most widely made use of catalyst provider, accounting for around 70% of commercial sustained catalysts. Light weight aluminum oxide has many kinds, not only different forms have various homes, but even the exact same type has different residential or commercial properties as a result of its various sources, such as density, pore structure, particular area and so forth.
These homes are of great significance for light weight aluminum oxide made use of as catalyst provider. Light weight aluminum oxide is primarily prepared from its hydroxide (additionally referred to as Light weight aluminum oxide hydrate or aluminum oxide hydrate).
Light weight aluminum oxide carrier shapes.
Business light weight aluminum oxide service providers are powdered, but most of them are built. Strip, round as well as ingot-shaped aluminum oxide are mainly made use of as catalyst service providers in fixed-bed reactors, while microspherical light weight aluminum oxide providers are mostly made use of in fluidized bed reactors. It can additionally be made right into special-shaped providers for certain catalytic procedures, such as ring, trefoil, honeycomb, fiber (see aluminum oxide fiber), etc. Along with solids, aluminum oxide sol is available for sale. The crucial parameters for choosing aluminum oxide are crystal form, pureness, specific surface, pore structure, bulk density and so on. The particular surface area of α& alpha;- aluminum oxide is really reduced( much less than 1m2/g), and also the certain surface of shift aluminum oxide is usually as much as 10 ~ 102m2/g.
Light weight aluminum oxide carrier homes.
Most of the formed industrial aluminum oxide providers are porous materials, as well as the pore dimension and also its circulation have a vital impact on the diffusion residential properties of catalysts in the stimulant bits in the catalytic process. The pore size of great pores can be less than 20 μ & mu; m, while that of coarse pores can reach micron level. The pore framework varies with species. All change aluminum oxide has water more or less, as well as there are some hydroxyl teams and also exposed aluminum atoms externally, which reveals the characteristics of B acid and also L acid (see acid-base driver), which has a crucial influence on the residential properties of Light weight aluminum oxide service provider. The surface area level of acidity is connected to the preparation conditions, particularly to the impurity ions and warm therapy temperature. Unfavorable ions such as halogen will certainly boost the surface level of acidity of aluminum oxide, which will certainly advertise the catalytic function of aluminum oxide itself for hydrocarbon cracking and isomerization.
Light weight aluminum oxide powder applications.
Aluminum oxide powder loaded with catalytic active elements. Light weight aluminum oxide with little certain surface (or products with only a small number of rugged pores) is normally used to support stimulant energetic parts with high certain task. The diffusion result in pores can be removed by using this type of provider, as well as the deep oxidation side reaction can be lowered at the same time for the function of careful oxidation. For example, the silver stimulant for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- light weight aluminum oxide. Aluminum oxide with large specific area has a well-developed pore structure, which can extremely spread the active parts of the catalyst right into particles, and also with the obstacle impact of the provider, the energetic element particles can be protected against from sintering and also maturing in the process of use. it is a sort of widely utilized aluminum oxide carrier. For example, the rare-earth elements platinum, rhodium and so forth are distributed on aluminum oxide support to make hydrogenation stimulant, which can enhance the application of precious metals.
The surface area acidity of light weight aluminum oxide and also the energetic components crammed form bifunctional stimulants. For example, the platinum-aluminum oxide catalyst used in platinum changing, in which aluminum oxide is not just a service provider, yet also among the energetic elements of the catalyst.
