The difference between inert alumina ceramic balls and activated alumina ceramic balls
The higher the alumina content, the better the alkali resistance and the better crushing strength. The inert ceramic balls can be used in conventional packed towers, but sometimes the design has higher requirements on the specific surface area and pressure drop of the ceramic balls. in the case of. Porcelain balls are divided into filler balls and grinding balls. Porcelain balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as a reaction.
The difference between inert alumina balls and activated alumina balls:
1. Inert alumina ball
Inert alumina ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as the covering support material and tower packing for the catalyst in the reactor. Inert alumina ceramic ball has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature changes in the production process. Its main function is to increase the distribution point of gas or liquid, and support and protect the active catalysis with low strength.
2. Activated alumina balls
Also known as modern water purification activated bauxite. The use of alumina (AL2O3) in the catalyst is usually called activated alumina. It is a porous, highly dispersed solid material with a large surface area, and its microporous surface has the properties required for catalysis. Such as adsorption performance, fluorine removal 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.
Alumina grinding ball has the characteristics of high hardness, high density, low wear, smooth surface, corrosion resistance, etc. It is the most ideal grinding medium for grinding glaze, blank and various powder materials.
