Aluminum Oxide Powder used as Carrier

What is light weight aluminum oxide provider? Light weight aluminum oxide service provider describes white powder or shaped Light weight aluminum oxide solid, which is the most extensively utilized catalyst provider, audit for about 70% of industrial sustained stimulants. Light weight aluminum oxide has many kinds, not only different forms have different residential or commercial properties, but even the same form has various homes as a result of its different sources, such as thickness, pore framework, specific area and so on.

These properties are of great significance for aluminum oxide utilized as stimulant provider. Aluminum oxide is mostly prepared from its hydroxide (additionally known as Aluminum oxide hydrate or aluminum oxide hydrate).
. Aluminum oxide carrier forms. Business light weight aluminum oxide service providers are powdered, but most of them are molded. Strip, spherical and ingot-shaped light weight aluminum oxide are mainly made use of as stimulant carriers in fixed-bed activators, while microspherical aluminum oxide carriers are mostly used in fluidized bed activators. It can likewise be made right into special-shaped service providers for specific catalytic processes, 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 available available. The essential parameters for picking light weight aluminum oxide are crystal kind, purity, details surface area, pore structure, bulk thickness and more. The certain surface area of α& alpha;- aluminum oxide is extremely low( much less than 1m2/g), and the specific surface area of change aluminum oxide is typically approximately 10 ~ 102m2/g.
. Light weight aluminum oxide service provider homes. A lot of the developed industrial aluminum oxide providers are permeable products, as well as the pore size and also its distribution have a vital influence on the diffusion residential properties of reactants in the catalyst fragments in the catalytic process. The pore dimension of fine pores can be less than 20 μ & mu; m, while that of rugged pores can get to micron degree. The pore framework differs with varieties. All transition aluminum oxide has water essentially, and there are some hydroxyl teams and subjected light weight aluminum atoms on the surface, which reveals the characteristics of B acid and also L acid (see acid-base catalyst), which has an important influence on the properties of Aluminum oxide carrier. The surface area acidity is associated with the preparation conditions, specifically to the impurity ions and also heat therapy temperature level. Unfavorable ions such as halogen will certainly improve the surface acidity of light weight aluminum oxide, which will certainly promote the catalytic feature of aluminum oxide itself for hydrocarbon fracturing and also isomerization.
. Aluminum oxide powder applications. Aluminum oxide powder loaded with catalytic energetic parts. Aluminum oxide with tiny particular surface area (or products with just a handful of coarse pores) is typically made use of to support stimulant active elements with high details activity. The diffusion impact in pores can be gotten rid of by utilizing this kind of carrier, as well as the deep oxidation side response can be minimized in the process for the objective of selective oxidation. For example, the silver driver for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- light weight aluminum oxide. Aluminum oxide with big certain area has a well-developed pore framework, which can extremely distribute the active parts of the driver right into particles, and with the obstacle impact of the service provider, the energetic component fragments can be stopped from sintering and growing up in the process of use. it is a sort of extensively utilized light weight aluminum oxide carrier. For example, the precious metals platinum, rhodium and so on are dispersed on aluminum oxide support to make hydrogenation catalyst, which can improve the usage of precious metals.

The surface area acidity of light weight aluminum oxide as well as the active elements packed type bifunctional stimulants. For instance, the platinum-aluminum oxide driver used in platinum changing, in which light weight aluminum oxide is not just a provider, but also one of the active elements of the driver.
