High Purity Alumina balls, also known as inert balls or catalyst support media are very important component in the catalytic process in the refinery, gas processing and petrochemical industry. It is commonly used to support catalyst and adsorbents products in the vessel or reactor. Its main function is to act as packing material and at the same time to support the catalyst bed in order to prevent breakthrough or loss of catalyst or adsorbent materials downstream of the reactor vessels due to the high pressure and temperature inside the reactor vessels during the operation.
Ceramic balls come in different sizes, which include 1”, 3/4”, 1/2”, 1/4” and 1/8”. These sizes are arranged layer by layer at the top and bottom of the vessel or reactor.
Typical application includes:
- Ammonia Production
- Methanol and hydrogen production (primarily reforming)
- Alkylation process using hydrogen fluoride at high temperature
- Naphtha reforming
- Isomerization
- Desiccant dryer
- Hydrocracker
- Petrochemical reaction
