F-220 activated alumina

Superior capacity and hydrothermal stability
BASF F-220 is a smooth sphere of activated alumina produced by BASF’s unique manufacturing process. It is available in a variety of sizes and is optimized for maximum adsorption capacity and hydrothermal stability.

BASF F-220 is an excellent desiccant for drying a wide variety of liquids and gases. Although all molecules are adsorbed to some extent on BASF F-220 activated alumina, those molecules having the highest polarity are preferentially absorbed.

Stream conditions such as pressure, concentration and molecular weight of the molecules, temperature and site competing molecules affect the efficiency of adsorption.

Applications:
- Drying. Nearly all gases and liquids can be dried with BASF F-220 activated alumina. Water removal is often necessary for efficient processing, storage, and transportation of fluids.

- Acid removal. Transformer oils, lubricating oils and refrigerants form degradation acids upon use. BASF F-220 will remove these acids during use. In the manufacture of chlorinated and/or fluorinated hydrocarbons, removal of these residual halides and water is essential for a nocorrosive product.

- Process stream purification. BASF F-220 is excellent for removal of highly polar compounds such as TBC, alcohols, ethers, etc. It also readily adsorbs heavy metal ions from hydrocarbons.

- Hydrocarbon adsorption. Under proper operating conditions, the pore size distributions and surface chemistry of activated aluminas are conducive to the adsorption of hydrocarbons.
