Aluminum Oxide Powder used as Carrier

What is light weight aluminum oxide provider? Aluminum oxide carrier refers to white powder or molded Light weight aluminum oxide strong, which is the most widely made use of stimulant provider, bookkeeping for around 70% of industrial sustained drivers. Aluminum oxide has numerous types, not just various kinds have different homes, but also the exact same form has different residential or commercial properties because of its various sources, such as thickness, pore structure, particular area and so forth.

These properties are of terrific value for light weight aluminum oxide utilized as stimulant carrier. Aluminum oxide is mostly prepared from its hydroxide (also called Aluminum oxide hydrate or light weight aluminum oxide hydrate).
. Aluminum oxide carrier forms. Business light weight aluminum oxide carriers are powdered, yet most of them are built. Strip, round and ingot-shaped light weight aluminum oxide are mostly used as catalyst providers in fixed-bed activators, while microspherical aluminum oxide providers are mainly used in fluidized bed activators. It can additionally be made into special-shaped carriers for certain catalytic processes, such as ring, trefoil, honeycomb, fiber (see light weight aluminum oxide fiber), etc. In addition to solids, light weight aluminum oxide sol is available for sale. The important parameters for choosing aluminum oxide are crystal type, purity, specific surface, pore framework, mass density and so forth. The particular area of α& alpha;- light weight aluminum oxide is really low( less than 1m2/g), as well as the details surface area of shift aluminum oxide is generally up to 10 ~ 102m2/g.
. Light weight aluminum oxide carrier buildings. Most of the created industrial light weight aluminum oxide carriers are porous materials, as well as the pore size and its distribution have an important influence on the diffusion residential or commercial properties of catalysts in the driver fragments in the catalytic process. The pore dimension of great pores can be less than 20 μ & mu; m, while that of coarse pores can get to micron level. The pore structure varies with types. All change aluminum oxide includes water basically, as well as there are some hydroxyl teams as well as revealed aluminum atoms externally, which shows the features of B acid as well as L acid (see acid-base catalyst), which has a crucial impact on the homes of Light weight aluminum oxide provider. The surface area level of acidity is associated with the preparation problems, specifically to the contamination ions as well as heat therapy temperature level. Unfavorable ions such as halogen will certainly boost the surface area level of acidity of light weight aluminum oxide, which will certainly promote the catalytic function of aluminum oxide itself for hydrocarbon fracturing and also isomerization.
. Aluminum oxide powder applications. Light weight aluminum oxide powder filled with catalytic energetic components. Light weight aluminum oxide with little certain area (or materials with only a handful of coarse pores) is typically made use of to support driver active elements with high certain activity. The diffusion impact in pores can be removed by using this type of service provider, as well as the deep oxidation side reaction can be lowered at the same time for the function of discerning oxidation. For example, the silver driver for the oxidation of ethylene to ethylene oxide is sustained by α& alpha;- light weight aluminum oxide. Aluminum oxide with large specific area has a strong pore structure, which can very disperse the active elements of the driver into particles, as well as with the obstacle effect of the carrier, the energetic component bits can be stopped from sintering as well as maturing in the procedure of use. it is a kind of commonly made use of light weight aluminum oxide provider. For instance, the precious metals platinum, rhodium and more are distributed on aluminum oxide assistance to make hydrogenation catalyst, which can improve the usage of rare-earth elements.

The surface area level of acidity of aluminum oxide and also the active elements packed type bifunctional drivers. For example, the platinum-aluminum oxide driver used in platinum reforming, in which light weight aluminum oxide is not just a service provider, yet likewise one of the active components of the stimulant.
