Difference between inert alumina balls and activated alumina balls

Inert alumina balls:

Industrial ceramic balls used in our daily industrial production refer to inert alumina ceramic balls. The usual sizes of inert alumina ceramic balls are: diameter 3mm, 6mm, 8mm, 10mm, 12mm, 13mm, 15mm, 20mm, 25mm, 40mm, 50mm, 60mm. Inert alumina ceramic balls are also called filler ceramic balls by many users. They are made of industrial alumina and kaolin as the main raw materials, formulated according to the production formula, formed and fired at high temperature. They have the appearance of regular spheres, chemical stability and thermal stability, can withstand the corrosion of acids, alkalis and other organic solvents, and can withstand the temperature changes in the production process. They are resistant to high temperature and high pressure, have low water absorption, and have stable chemical properties.

The difference between inert alumina balls and activated alumina balls:

1. Inert alumina balls

Inert alumina ceramic balls are widely used in the petroleum, chemical, fertilizer, natural gas and environmental protection industries as a covering support material and tower filler for catalysts in reactors. Inert alumina ceramic balls are resistant to high temperature and high pressure, have low water absorption and stable chemical properties. They can withstand corrosion from acids, alkalis and other organic solvents, and can withstand temperature changes during the production process. Its main function is to increase the distribution points of gas or liquid, and to support and protect active catalysts with low strength.

2. Activated alumina balls

Also known as modern water purification activated alumina. The use of alumina (AL2O3) in catalysts is usually called activated alumina. It is a porous, highly dispersed solid material with a large surface area. Its microporous surface has the characteristics required for catalysis, such as adsorption performance, defluorination performance, drying performance, surface activity, excellent thermal stability, etc., so it is widely used as a household desiccant and a catalyst and catalyst carrier for chemical reactions.
