Aluminum Oxide Powder used as Carrier
What is aluminum oxide carrier?
Aluminum oxide provider refers to white powder or shaped Light weight aluminum oxide strong, which is the most extensively used catalyst provider, accounting for around 70% of commercial supported catalysts. Light weight aluminum oxide has several types, not only various kinds have various residential or commercial properties, however also the very same kind has different residential or commercial properties because of its different resources, such as thickness, pore framework, specific area and more.
These buildings are of terrific relevance for aluminum oxide used as catalyst service provider. Aluminum oxide is mainly prepared from its hydroxide (likewise known as Light weight aluminum oxide hydrate or light weight aluminum oxide hydrate).
Aluminum oxide carrier shapes.
Industrial aluminum oxide providers are powdered, however the majority of them are molded. Strip, round and also ingot-shaped aluminum oxide are mainly made use of as stimulant service providers in fixed-bed reactors, while microspherical light weight aluminum oxide providers are mostly utilized in fluidized bed reactors. It can likewise be made right into special-shaped service providers for specific catalytic procedures, such as ring, trefoil, honeycomb, fiber (see light weight aluminum oxide fiber), etc. Along with solids, light weight aluminum oxide sol is available to buy. The important parameters for choosing aluminum oxide are crystal kind, purity, details surface, pore framework, mass thickness and so on. The certain area of α& alpha;- aluminum oxide is extremely low( less than 1m2/g), as well as the details surface area of change light weight aluminum oxide is typically as much as 10 ~ 102m2/g.
Aluminum oxide carrier residential properties.
Most of the developed industrial aluminum oxide carriers are permeable materials, and also the pore dimension and its distribution have a vital influence on the diffusion homes of reactants in the stimulant fragments 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 differs with varieties. All change light weight aluminum oxide contains water essentially, and also there are some hydroxyl groups and revealed light weight aluminum atoms externally, which shows the characteristics of B acid and L acid (see acid-base stimulant), which has a crucial influence on the buildings of Light weight aluminum oxide provider. The surface level of acidity is associated with the preparation conditions, particularly to the pollutant ions and warmth treatment temperature. Adverse ions such as halogen will enhance the surface acidity of aluminum oxide, which will certainly promote the catalytic feature of aluminum oxide itself for hydrocarbon fracturing and also isomerization.
Aluminum oxide powder applications.
Light weight aluminum oxide powder packed with catalytic active parts. Aluminum oxide with small specific area (or materials with only a small number of crude pores) is generally used to support stimulant energetic components with high specific activity. The diffusion impact in pores can be gotten rid of by using this type of carrier, as well as the deep oxidation side reaction can be lowered at the same time for the objective of discerning oxidation. As an example, the silver stimulant for the oxidation of ethylene to ethylene oxide is supported by α& alpha;- light weight aluminum oxide. Aluminum oxide with big certain area has a strong pore framework, which can extremely spread the energetic elements of the driver right into fragments, and with the barrier impact of the carrier, the energetic element particles can be stopped from sintering and maturing in the procedure of use. it is a kind of extensively made use of aluminum oxide provider. For instance, the precious metals platinum, rhodium and so forth are distributed on light weight aluminum oxide assistance to make hydrogenation stimulant, which can improve the use of rare-earth elements.
The surface acidity of light weight aluminum oxide and also the active components crammed type bifunctional drivers. For example, the platinum-aluminum oxide driver used in platinum reforming, in which aluminum oxide is not only a provider, however likewise among the energetic elements of the catalyst.
