Alumina Inert Ceramic Balls

Inert ceramic balls (catalyst bed support balls) with high temperature and high-pressure resistance, low water absorption, chemical stability, acid and alkali resistance, resistance to organic solvent corrosion. Inert alumina balls (catalyst support balls) can withstand the temperature changes in the production process.

Inert Alumina balls (inert ceramic balls) Catalyst bed Support Media 

Inert ceramic balls are pressed silicate ceramic catalyst support balls with 23-26% aluminum oxide within them. Alumina ceramic support balls (catalyst bed support balls) come in different sizes from 3 mm to 50 mm in diameter. 

High-purity inert alumina balls,also known as high-purity catalyst inert ceramic balls, have the advantages of good thermal shock stability, large heat storage, high strength, easy cleaning, and reusability.

Inert ceramic balls Catalyst bed Support balls applications

Inert ceramic balls are used as the support and covering material of the catalyst in the reactor, which can buffer the impact of vapor and liquid entering the reactor on the catalyst, protect the catalyst, and Optimize the distribution of liquids and gases in the reactor. Inert alumina balls (ceramic support 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. They’re used as grinding bodies in ball mills, but catalyst bed support balls also fill and support the catalyst layer in both catalytic columns and catalytic reactors by amplifying the distribution of gases and liquids and buffering their impact on the catalyst.

Inert alumina Balls (ceramic support balls) Catalyst Bed Support balls advantage

Inert ceramic balls are widely used as catalyst bed support in the world. Unaltered by thermal shocks, pressure, acid, alkali, and organic solvents, catalyst bed support balls (ceramic support balls) successfully safeguard the catalysts in the reactors and tower packing of natural gas, petroleum, chemical fertilizer, and environmental protection industries.

Other properties of inert alumina ball include chemical stability, mechanical strength, low surface profile, low water absorption, and bulk material uniformity. 

  • Chemical inertness
  • Mechanical strength and stability
  • Low surface profile
  • Bulk material uniformity
