Aluminum Oxide Powder used as Carrier
What is aluminum oxide carrier?
Light weight aluminum oxide service provider refers to white powder or molded Light weight aluminum oxide solid, which is one of the most commonly made use of stimulant provider, accounting for about 70% of commercial sustained drivers. Aluminum oxide has lots of forms, not just different kinds have various residential or commercial properties, however also the very same kind has different properties because of its different sources, such as thickness, pore structure, certain area and more.
These residential or commercial properties are of wonderful significance for light weight aluminum oxide utilized as stimulant provider. Light weight aluminum oxide is mostly prepared from its hydroxide (also called Light weight aluminum oxide hydrate or light weight aluminum oxide hydrate).
Aluminum oxide carrier forms.
Commercial light weight aluminum oxide carriers are powdered, yet the majority of them are built. Strip, spherical and ingot-shaped light weight aluminum oxide are mainly used as catalyst carriers in fixed-bed activators, while microspherical aluminum oxide carriers are mostly used in fluidized bed activators. It can also be made right into special-shaped providers for particular catalytic processes, such as ring, trefoil, honeycomb, fiber (see light weight aluminum oxide fiber), etc. In addition to solids, aluminum oxide sol is readily available up for sale. The important parameters for choosing aluminum oxide are crystal kind, pureness, certain surface, pore framework, bulk density and so forth. The particular surface of α& alpha;- aluminum oxide is very reduced( less than 1m2/g), and the certain area of transition aluminum oxide is generally up to 10 ~ 102m2/g.
Light weight aluminum oxide service provider homes.
The majority of the formed commercial light weight aluminum oxide providers are porous materials, as well as the pore dimension and also its distribution have a crucial influence on the diffusion properties of catalysts in the stimulant bits in the catalytic process. The pore dimension of great pores can be much less than 20 μ & mu; m, while that of crude pores can get to micron level. The pore framework differs with types. All change light weight aluminum oxide contains water more or less, and also there are some hydroxyl groups and subjected aluminum atoms on the surface, which reveals the characteristics of B acid and L acid (see acid-base catalyst), which has a vital influence on the homes of Light weight aluminum oxide carrier. The surface area level of acidity is connected to the prep work conditions, particularly to the pollutant ions and also warmth treatment temperature. Negative ions such as halogen will certainly enhance the surface level of acidity of light weight aluminum oxide, which will advertise the catalytic feature of aluminum oxide itself for hydrocarbon breaking and isomerization.
Aluminum oxide powder applications.
Light weight aluminum oxide powder filled with catalytic active parts. Aluminum oxide with tiny particular surface (or materials with only a handful of rugged pores) is typically used to support driver active parts with high particular activity. The diffusion impact in pores can be eliminated by using this kind of carrier, and the deep oxidation side response can be minimized in the process for the objective of selective oxidation. As an example, the silver stimulant for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- aluminum oxide. Aluminum oxide with huge particular surface has a well-developed pore structure, which can extremely spread the active components of the stimulant into particles, and also with the barrier result of the service provider, the active part particles can be protected against from sintering as well as growing up in the procedure of usage. it is a kind of commonly used light weight aluminum oxide provider. For instance, the precious metals platinum, rhodium and so on are distributed on aluminum oxide support to make hydrogenation catalyst, which can boost the use of precious metals.
The surface level of acidity of light weight aluminum oxide and the energetic components crammed kind bifunctional stimulants. For example, the platinum-aluminum oxide driver used in platinum reforming, in which light weight aluminum oxide is not just a provider, but likewise one of the active elements of the driver.
