HYSG-18SILICAGEL alumina beads

The aluminum-containing silica gel has a spherical shape, high hardness, high compressive strength and low abrasion. Due to its large surface area, the SG-18 alumina microsphere has a high adsorption capacity for water vapor. Not only can the SG-18 be regenerated, it can be significantly less efficient, it is economical, and it is easy to handle and does not have any known adverse effects on the environment.

Applications        
Due to their high adsorptive capacity SG-18 alumina beads have a multitude of uses: Dynamic adsorption (removal of moisture from a continuously lowing gas or liquid stream) as well as static adsorption (removal of moisture and control of humidity in packaging and other enclosed spaces without induced air flow). Due to their special surface structure SG-18 alumina beads are preferably being used for the adsorption of water vapour and the recovery of heavy ydrocarbons containing in natural gas. These hydrocarbons can be recovered. 

Packing            
Airtight in 25 kg – bags,cartons, reconditioned 150 kg

steel drums or 1000 kg-bulk bags with PE-Inliner 

Handling           
SG-18 must always be kept in airtight containers to avoid pre-adsorption with water vapour. Face masks should be used at continual exposure to extensive dusting.
