ZEOCHEM ALOX F activated alumina has high crush strength and very low abrasion. ALOX F allows for minimum polymerization of unsaturated hydrocarbons below 65°C.

ZEOCHEM ALOX F activated alumina is used in the drying of gases (such as Air, CO2, SF6, NH3, CO, H2S, and Cl2) and liquids (such as gasoline and chlorinated, fluorinated, or aromatic hydrocarbons) where high thermal and mechanical resistance is required.

ZEOCHEM ALOX F is also used as a guard layer at the inlet of many vapor phase molecular sieve beds. The activated alumina product has high capacity for any liquids that may be  present in the feed to the unit. In this service, ALOX F helps protect the molecular sieve bed from damage as a result of heavy hydrocarbon and moisture condensation and liquids carryover from upstream process units.
