Catalyst Support – Alumina Balls

99.5% High Purity Alumina Balls

The main characters of HuaMing 99.5% high purity alumina balls

  1. Withstand high temperature 1850.℃
  2. Excellent mechanical strength, resistance to thermal shock, nice antistrip performance, anti-corrosive.
  3. Chemical inertness.

99.5% high purity alumina balls are widely used in petroleum industry. It can be used as catalyst / absorber support media in the reactor and tower packing material with main function to increase the gas or liquid distribution points, support and protect the active catalyst.
