What are the characteristics of carrier alumina spheres and activated alumina spheres?

1. Activated alumina is a porous, highly dispersible solid material having a large surface area and a microporous surface having catalytic properties such as adsorption properties, surface activity and excellent thermal stability. It has the characteristics of high strength, small abrasion, no water softening, no expansion, no powdering, no cracking, etc. It is widely used as a catalyst and catalyst carrier for chemical reactions.

2. Inert alumina balls are referred to as inert ceramic balls. Made of high quality chemical porcelain clay, it has high strength, high chemical stability and thermal stability. It can withstand high temperatures, high pressures and corrosion of acids, bases, salts and various organic solvents. Widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries.
3. Inert alumina spheres serve as a support and coating material for the catalyst in the reactor, buffering the effects of liquids and gases entering the reactor on the catalyst, protecting the catalyst, and improving the distribution of liquids and gases. reactor. Its primary role is to increase the gas or liquid distribution point to support and protect low strength active catalysts.
4. Catalysts in various reactions such as reforming, hydrogenation, dehydrogenation, dehydration, dehalogenation, disproportionation and isomerization can be supported in the oxidation. On the aluminum ball.
Alumina balls are also known as modern pure water activated soils. The use of alumina (AL 2 O 3 ), commonly referred to as activated alumina, in the catalyst is a porous, highly dispersible solid material having a large surface area and a microporous surface having the desired properties for catalysis. Such as adsorption performance, fluorine removal performance, drying performance, surface activity, excellent thermal stability, etc., it is widely used as a catalyst and catalyst carrier for household desiccants and chemical reactions.
6. The higher the alumina content, the better the alkali resistance and the better the crush strength. Inert ceramic balls can be used in conventional packed towers, but sometimes designed to have a larger specific surface area, pressure drop, and the like. In the case of large demand. Porcelain balls are divided into filled ceramic balls and ground ceramic balls. Porcelain balls are widely used in industries such as petroleum, chemical, fertilizer, natural gas and environmental protection.
