Aluminum Oxide Powder used as Carrier

What does it mean to be an aluminum oxide carrier

Aluminum oxide

White powder, molded Aluminum oxide, solid is called carrier. It accounts for approximately 70% of industrial support catalysts. Aluminium oxide comes in many forms. Different forms not only have different properties; even different forms can exhibit different properties due to their different sources.

Aluminum oxide is used as a catalyst. These properties are crucial. Aluminium oxide can be prepared mostly from the hydroxide. Also known as aluminum oxide hydrate, or aluminum oxide.

Aluminum oxide carrier shapes

Although aluminum oxide carrier powders are available in commercial quantities, most are moldable. Most aluminum oxides are used as catalyst carriers for fixed-bed reactors. However, they are mainly used to make ingots and strip shapes. Aluminum oxide can be made into specific-shaped carriers, including honeycomb and rings, for catalytic processes like trefoil, ring, or fiber. Aluminium oxide sol can also be purchased in solids. Crystal form, purity and bulk density are all important criteria for choosing aluminum oxide. Specific surface area for a-aluminumoxide is extremely low, less than 1m2/g. In contrast, the specific surface area for transition aluminum oxide ranges from 10102m2/g to up to 10102m2/g.

Properties of aluminum oxide carriers

Porous materials make up most of commercial aluminum oxide carriers. The pore sizes and distributions have a significant impact on the diffusion properties in the catalytic processes. While fine pores have an average size of less than 20mm2, coarse pores are larger and can exceed microns. The structure of pores varies depending on the species. Every type of transition aluminium oxide is water-rich. Additionally, there are some hydroxyl group and exposed aluminum atoms at the surface. This shows that the aluminum oxide carrier has important properties. Temperature and the prep conditions can affect the surface acidity. Aluminum oxide will have a higher surface acidity due to the presence of halogen and other negative ions. These ions will also promote aluminum oxide’s ability to catalyze hydrocarbon cracking or isomerization.

Application of aluminum oxide powder

Catalytic active elements are added to aluminum oxide powder. Supporting catalyst active ingredients with high specific activities is possible with aluminum oxide having a limited specific surface area. This can be used for materials that have fewer pores or with very few coarse pores. This type of carrier is able to eliminate pores’ diffusion effects and reduce deep oxidation. The support for the oxidation from ethylene to an aluminum oxide catalyst is a-aluminum. A large surface area aluminum oxide can disperse active components easily into tiny particles. The barrier function of the carrier can prevent active component particles from becoming sinterable and grow up during the use. This is the most widely-used aluminum oxide carrier. The aluminum oxide supports can be used to disperse precious metals like platinum, rhodium, and other metals.

Aluminum oxide’s aluminum surface acidity combined with the active components form bifunctional catalysts. Platinum-aluminumoxide catalyst for platinum reforming. Aluminum oxide acts not only as a carrier but is also an active component of the catalyst.
