Solutions for chemical processes and environmental protection
Activated aluminas are produced from aluminium hydroxide feedstocks by controlled thermal treatment in order to eliminate most of the water in the crystal lattice. The resulting crystal phase is mostly boehmite, or at higher temperatures, transitional alumina also called gamma alumina.
COMPALOX is a granular activated alumina based on a unique process. The crystal structure is mainly boehmite. COMPALOX is destined for several applications in the field of adsoprtions and catalysis.
Specific features of COMPALOX® are:
| • |
large specific surface area |
| • |
high pore volume |
| • |
defined pore size distribution |
| • |
specific catalytic reactivity |
| • |
specific adsorptive capacity |
| • |
high crushing strength and therefore low dust formation |
Compalox®-applications:
In order to solve specific adsorption or catalytic problems, COMPALOX can be modified as a tailor-made product by variation of the activation process or by using dopants meeting the customer's requirements.
Some typical applications of COMPALOX are:
| • |
desiccant (drying of organic and inorganic gases and liquids) |
| • |
catalyst in hydrogen peroxide production |
| • |
purification of process liquids and gases |
| • |
enrichment and recovery of defined substances from diluted systems |
| • |
HCI and residue monomer adsorption in reaction streams based upon gases or liquids |
| • |
air purification |
| • |
water purification by the adsorption of arsenic, fluoride, phosphate and heavy metals |
| • |
chromatography |
