Product Description:
Activated Alumina are a family of aluminum oxides (Al2O3) used as a desiccant, or drying agent, for industrial liquids and gases such as air, nitrogen, oxygen, carbon dioxide and hydrocarbons.
Activated alumina is used for a wide range of adsorbent and catalyst applications including the adsorption of catalysts in polyethylene production, in hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, fluoride and in sulfur removal from gas streams (Claus Catalyst process). Finally Activated Alumina are also used as filters for fluoride, arsenic and selenium in drinking water.
Activated alumina are both high surface area beads and crushed products that are "activated" by a proprietary process to achieve specific surface chemistry and reactivity. Commonly used as adsorbents, desiccants and catalysts, the chemistry, size and structure of these alumina are tailored to specific applications Additives are also commonly used with activated alumina to achieve even greater performance in certain applications e.g. removal of sulphur and chloride in refinery applications.
Activated Alumina Applications:
Desiccant/Dehydration
Hydrogen peroxide manufacturing
Polyethylene production
Defluorination of alkylation product streams
Water treatment (fluoride and arsenic removal)
Aqueous treatment (removal of hydrogen sulphide, carbonyl chloride and hydrogen chloride)
Off-gas treatment (carbon dioxide, hydrogen chloride and hydrogen sulphide removal)
Removal of alcohol and ether from liquid streams
