Aluminum Oxide Powder used as Carrier
What is light weight aluminum oxide service provider?
Aluminum oxide provider refers to white powder or molded Light weight aluminum oxide strong, which is the most extensively used driver carrier, bookkeeping for about 70% of commercial sustained catalysts. Aluminum oxide has many kinds, not only various forms have different residential properties, however also the same type has different buildings as a result of its various sources, such as density, pore framework, specific surface area and so forth.
These buildings are of fantastic importance for aluminum oxide used as catalyst carrier. Light weight aluminum oxide is mostly prepared from its hydroxide (also referred to as Light weight aluminum oxide hydrate or light weight aluminum oxide hydrate).
Aluminum oxide carrier forms.
Commercial light weight aluminum oxide providers are powdered, but the majority of them are built. Strip, round as well as ingot-shaped light weight aluminum oxide are mostly made use of as stimulant service providers in fixed-bed activators, while microspherical aluminum oxide carriers are mostly used in fluidized bed reactors. It can additionally be made into special-shaped providers for particular catalytic procedures, 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 offered available. The vital criteria for choosing light weight aluminum oxide are crystal form, purity, certain surface, pore structure, bulk thickness and so on. The particular area of α& alpha;- light weight aluminum oxide is really reduced( less than 1m2/g), as well as the certain area of transition light weight aluminum oxide is normally as much as 10 ~ 102m2/g.
Aluminum oxide service provider properties.
Most of the developed commercial aluminum oxide carriers are porous materials, and the pore size and its distribution have a crucial impact on the diffusion buildings of catalysts in the stimulant bits in the catalytic process. The pore dimension of fine 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 shift light weight aluminum oxide contains water essentially, and also there are some hydroxyl teams and exposed light weight aluminum atoms externally, which reveals the characteristics of B acid as well as L acid (see acid-base catalyst), which has a vital impact on the residential or commercial properties of Aluminum oxide service provider. The surface area acidity is associated with the prep work conditions, particularly to the pollutant ions and also warmth treatment temperature level. Negative ions such as halogen will certainly enhance the surface area acidity of aluminum oxide, which will certainly promote the catalytic function of aluminum oxide itself for hydrocarbon breaking as well as isomerization.
Aluminum oxide powder applications.
Aluminum oxide powder loaded with catalytic energetic parts. Aluminum oxide with tiny specific surface (or materials with just a handful of coarse pores) is typically used to sustain stimulant active elements with high certain activity. The diffusion effect in pores can be removed by using this type of service provider, and the deep oxidation side response can be minimized at the same time for the purpose of discerning oxidation. As an 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 surface has a well-developed pore structure, which can very disperse the active elements of the catalyst into particles, and also with the obstacle result of the service provider, the energetic element bits can be protected against from sintering and also maturing in the process of usage. it is a type of extensively utilized aluminum oxide carrier. For example, the rare-earth elements platinum, rhodium and so on are spread on aluminum oxide assistance to make hydrogenation driver, which can enhance the use of precious metals.
The surface area level of acidity of aluminum oxide and the active elements loaded type bifunctional drivers. For instance, the platinum-aluminum oxide driver utilized in platinum reforming, in which aluminum oxide is not only a carrier, but also among the energetic components of the driver.
