Aluminum Oxide Powder used as Carrier
What is aluminum oxide carrier?
Aluminum oxide provider refers to white powder or molded Light weight aluminum oxide solid, which is one of the most extensively utilized catalyst carrier, accounting for around 70% of commercial supported catalysts. Light weight aluminum oxide has lots of kinds, not just different kinds have different residential properties, yet even the same kind has different properties because of its different resources, such as density, pore structure, specific surface area and more.
These buildings are of wonderful value for aluminum oxide utilized as driver service provider. Light weight aluminum oxide is primarily prepared from its hydroxide (also known as Aluminum oxide hydrate or light weight aluminum oxide hydrate).
Aluminum oxide carrier forms.
Business aluminum oxide carriers are powdered, but most of them are molded. Strip, spherical and ingot-shaped aluminum oxide are mainly used as driver providers in fixed-bed activators, while microspherical aluminum oxide providers are mainly utilized in fluidized bed activators. It can likewise be made into special-shaped carriers for details catalytic processes, such as ring, trefoil, honeycomb, fiber (see aluminum oxide fiber), and so on. Along with solids, light weight aluminum oxide sol is offered to buy. The vital criteria for choosing light weight aluminum oxide are crystal type, purity, specific surface, pore structure, mass thickness and so forth. The certain area of α& alpha;- aluminum oxide is very reduced( less than 1m2/g), and the details area of transition aluminum oxide is generally as much as 10 ~ 102m2/g.
Light weight aluminum oxide carrier residential properties.
Most of the created industrial light weight aluminum oxide providers are permeable products, and the pore size and its distribution have a crucial influence on the diffusion residential properties of reactants in the stimulant fragments 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 get to micron level. The pore framework varies with types. All change aluminum oxide has water basically, and also there are some hydroxyl groups as well as revealed light weight aluminum atoms externally, which reveals the characteristics of B acid as well as L acid (see acid-base stimulant), which has a vital impact on the residential or commercial properties of Light weight aluminum oxide service provider. The surface area acidity is connected to the prep work problems, especially to the impurity ions and also warm therapy temperature. Negative ions such as halogen will certainly improve the surface area level of acidity of aluminum oxide, which will certainly advertise the catalytic function of light weight aluminum oxide itself for hydrocarbon cracking as well as isomerization.
Aluminum oxide powder applications.
Aluminum oxide powder filled with catalytic energetic elements. Aluminum oxide with tiny certain area (or products with only a small number of coarse pores) is normally made use of to support driver active elements with high specific activity. The diffusion impact in pores can be eliminated by using this sort of provider, as well as the deep oxidation side reaction can be decreased while doing so for the objective of discerning oxidation. As an example, the silver catalyst for the oxidation of ethylene to ethylene oxide is supported by α& alpha;- aluminum oxide. Aluminum oxide with huge specific surface area has a strong pore framework, which can highly disperse the energetic components of the driver into bits, and also with the barrier impact of the provider, the energetic element fragments can be protected against from sintering and maturing in the procedure of usage. it is a sort of commonly made use of aluminum oxide provider. For instance, the precious metals platinum, rhodium and so on are dispersed on light weight aluminum oxide assistance to make hydrogenation stimulant, which can improve the usage of rare-earth elements.
The surface area acidity of light weight aluminum oxide and also the energetic elements crammed form bifunctional stimulants. As an example, the platinum-aluminum oxide stimulant made use of in platinum changing, in which light weight aluminum oxide is not just a service provider, yet also one of the energetic components of the catalyst.
