Large Pore Volume (Diameter) Alumina Microsphere

Large pore volume (diameter) alumina microsphere

The appearance is white or reddish particles like sand, non-toxic,tasteless,insoluble in water and organic

solvents,soluble in acid and alkali.

Alumina microspheres as a catalyst carrier, has many advantages

  • small particles fast reaction
  • is easily dipped rare earth,metal,etc
  • has high activity

Main application

  • petroleum chemical fluidized bed catalyst for the pharmaceutical industry
  • catalyst
  • chemical purification catalyst and desiccant,adsorbent
  • melamine and automobile exhaust catalyst carrier

Note: we can adjust indicators according to the users request

We have our own unique technology on LS microspheres products,which feather is in larger volume,high specific surface,low wear,concentration of particle size distribution,etc.
