The Difference Between Activated Alumina And Inert Ceramic Balls

The Difference Between Activated Alumina And Inert Ceramic Balls


For customers who are not familiar with the chemical industry, sometimes they can't tell the difference between activated alumina and ceramic balls, and can't see the difference between them? They look similar and both contain alumina, but the ceramic balls are ordinary hard ceramic balls, and the purity of Al2O3 ranges from 17-19%, 23-26%, 30%, 65% or even 92%. The color varies from gray, grayish yellow to white. And it's inert and won't react with other chemicals. However, activated alumina cannot be called alumina ball, it is a white spherical particle that is activated and has the ability to adsorb certain substances.

Activated alumina is an adsorbent, and the same type includes molecular sieve and silica gel, which can be used to adsorb some polar substances. Activated alumina is active and will react with materials. Activated alumina balls have many capillary channels and large surface area, which can be used as adsorbent, desiccant and catalyst carrier. At the same time, it is also determined according to the polarity of the adsorbate, and has a strong affinity for water, oxides, acetic acid, alkali, etc.
XINTAO activated alumina manufacturer, the activated alumina produced has high strength, low wear, no expansion, no pulverization, and no cracking.
Activated alumina balls can be used for deep drying of petroleum cracking gas, ethylene propylene gas, hydrogen production, air separation unit, instrument air dryer, fluorination treatment of hydrogen peroxide, etc., and can also remove sulfur-containing gas hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons Pollutants in exhaust gas, especially suitable for defluoridation of fluorinated water.

Inert alumina ceramic ball is a kind of ceramic ball, which is used as support media before and after loading catalyst or adsorbent layer in the reaction. Inert alumina balls are inert, because they will not react with materials, and have high strength, acid and alkali resistance, so as to support and protect and prolong the reaction.
XINTAO ceramic ball m
anufacturer, inert ceramic balls have the characteristics of high strength, high chemical stability and high thermal stability. Inert ceramic balls can withstand high pressure, acid, alkali, salt and various organic solvent corrosion.

Inert ceramic balls are mainly used in petroleum, chemical, fertilizer, natural gas and environmental protection industries. As the carrier and covering material of the catalyst in the reactor, the inert ceramic ball can buffer the impact of the liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor.
Ceramic balls with a composition content higher than 90% are usually called alumina balls, and their appearance is most similar to activated alumina, all of which are white granular spheres, but in terms of appearance, weight, and application, it can be seen that there are many ceramic balls. obvious difference.
