What does it mean to be an aluminum oxide carrierAluminum 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 hydrate.
Aluminum oxide carrier shapesAlthough aluminum oxide carrier powders are available in commercial quantities, most are moldable. Most aluminum oxide carriers used for catalysts in fixed-bed reactions are spherical, ingot and strip-shaped. However, microspherical aluminumoxid carriers are most commonly used in fluidized beds reactors. Aluminum oxide can be made into specific-shaped carriers, including honeycomb and rings, for catalytic processes like trefoil and ring. Aluminium oxide sol can also be purchased in solids. Crystal form, purity and bulk density are all important criteria for choosing aluminum oxide. The specific surface of an aluminum oxide (less that 1m2/g) is extremely small, while the surface of transition aluminum dioxide is typically up to 10102m2/g.
Properties of aluminum oxide carriersPorous materials make up most of the commercial aluminum oxide carriers. The pore sizes and their 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 powderCatalytic 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 a 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 particles from becoming sintered and growing in 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.
