Aluminum Oxide Powder used as Carrier
What is aluminum oxide carrier?
Light weight aluminum oxide service provider describes white powder or molded Light weight aluminum oxide solid, which is the most commonly used stimulant carrier, accountancy for around 70% of commercial supported catalysts. Light weight aluminum oxide has numerous types, not only various kinds have various residential or commercial properties, however even the very same form has different homes as a result of its different sources, such as thickness, pore structure, certain area and so on.
These properties are of wonderful importance for light weight aluminum oxide made use of as stimulant provider. Light weight aluminum oxide is mostly prepared from its hydroxide (likewise referred to as Light weight aluminum oxide hydrate or aluminum oxide hydrate).
Aluminum oxide carrier forms.
Commercial aluminum oxide carriers are powdered, but a lot of them are formed. Strip, spherical as well as ingot-shaped light weight aluminum oxide are mostly made use of as catalyst carriers in fixed-bed reactors, while microspherical aluminum oxide providers are mainly used in fluidized bed activators. It can also be made right into special-shaped providers for certain catalytic procedures, such as ring, trefoil, honeycomb, fiber (see aluminum oxide fiber), and so on. Along with solids, aluminum oxide sol is offered to buy. The crucial parameters for choosing light weight aluminum oxide are crystal form, purity, specific surface area, pore framework, mass density and so forth. The certain surface of α& alpha;- light weight aluminum oxide is extremely reduced( less than 1m2/g), as well as the certain area of transition light weight aluminum oxide is generally up to 10 ~ 102m2/g.
Aluminum oxide service provider properties.
Most of the created commercial light weight aluminum oxide carriers are porous products, and also the pore dimension and its circulation have an essential impact on the diffusion residential or commercial properties of reactants in the driver bits in the catalytic process. The pore size of fine pores can be much less than 20 μ & mu; m, while that of crude pores can reach micron level. The pore framework varies with varieties. All change light weight aluminum oxide has water basically, as well as there are some hydroxyl groups as well as revealed light weight aluminum atoms externally, which shows the features of B acid and L acid (see acid-base catalyst), which has a vital influence on the properties of Aluminum oxide service provider. The surface acidity is associated with the preparation conditions, specifically to the pollutant ions and also warmth therapy temperature level. Negative ions such as halogen will certainly boost the surface area level of acidity of light weight aluminum oxide, which will advertise the catalytic function of light weight aluminum oxide itself for hydrocarbon cracking as well as isomerization.
Aluminum oxide powder applications.
Aluminum oxide powder loaded with catalytic active elements. Aluminum oxide with small details surface area (or materials with just a handful of coarse pores) is generally made use of to support catalyst active components with high details task. The diffusion result in pores can be eliminated by utilizing this kind of provider, and also the deep oxidation side reaction can be lowered in the process for the objective of discerning oxidation. For example, the silver catalyst for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- light weight aluminum oxide. Light weight aluminum oxide with big particular surface area has a strong pore framework, which can very disperse the active parts of the stimulant right into particles, and with the barrier impact of the provider, the active part particles can be stopped from sintering and also growing up in the process of use. it is a type of widely utilized aluminum oxide provider. For instance, the precious metals platinum, rhodium and so on are distributed on aluminum oxide support to make hydrogenation driver, which can boost the utilization of rare-earth elements.
The surface area level of acidity of aluminum oxide and the active elements crammed type bifunctional drivers. As an example, the platinum-aluminum oxide driver utilized in platinum reforming, in which light weight aluminum oxide is not only a carrier, yet likewise among the energetic parts of the catalyst.
