Application
A-AS-04 activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material;
A-AS-DF activated alumina is also widely used to remove fluoride from drinking water. Basically, the more alumina in the filter, the less fluoride will be in the final, filtered water.
A-AS-MS is for absorbent H2O2
A-AS-AC is for chlorine absorbent
A-AS-C in hydrogen peroxide production, as a selective adsorbent for many chemicals including, in removal from gas streams .
A-AS-A activated alumina is used as a charge material in foreline traps to prevent generated by from backstreaming into the system
Industry standard HG/T39272007 Activated Alumina is issued by Zhengzhou Mahaco Industrial Co,Ltd
Activated Alumina: The Versatile Desiccant, Adsorbent, and Catalyst Support
ZHENGZHOU MAHACO INDUSTRIAL CO., LTD. is a premier manufacturer of high-performance Activated Alumina, a multifunctional material engineered to excel in three critical industrial roles: as a powerful desiccant, a selective adsorbent, and a stable catalyst support. Our activated alumina balls deliver unmatched reliability in moisture removal, impurity purification, and catalytic processes across diverse sectors.
1. Superior Industrial Desiccant
As a high-capacity activated alumina desiccant, our product is the preferred choice for deep drying applications due to its exceptional moisture adsorption, thermal stability, and regeneration capability.
Primary Applications:
Compressed Air & Gas Drying: The ideal desiccant for compressed air dryers (heatless, heated, and blower purge types), ensuring instrument-quality air by achieving dew points as low as -70°C.
Petrochemical Drying: Used extensively as a deep bed desiccant for drying liquid and gaseous hydrocarbons (e.g., LPG, natural gas, reformer feeds) to prevent pipeline corrosion and freezing.
Insulating Glass: Serves as a key desiccant for insulating glass units, absorbing residual moisture between panes to prevent fogging.
Key Advantage: Exceptional crush strength withstands high pressure in deep beds, and its ability to be regenerated multiple times offers a superior lifetime value.
2. High-Efficiency Adsorbent
Beyond moisture, our activated alumina adsorbent selectively removes a wide range of impurities from gases and liquids through surface adsorption and pore filtration.
Primary Applications:
Fluoride & Arsenic Removal: The leading adsorbent for water treatment, effectively removing fluoride, arsenic, and other contaminants from drinking water.
Acid Gas Removal: Acts as an adsorbent for acid gas removal, capturing HCl, HF, and SOx from process streams in chemical and petrochemical plants.
Liquid & Gas Purification: Removes impurities and polar compounds from organic liquids, solvents, and various industrial gas streams.
3. Reliable Catalyst Support (Carrier)
The high surface area, inert nature, and thermal stability of our activated alumina balls make them an excellent catalyst support material (or carrier) for numerous chemical reactions.
Primary Applications:
Petrochemical & Refining: Widely used as a catalyst support in hydrogen peroxide production, Claus catalyst for sulfur recovery, and in various hydrotreating and reforming processes.
Chemical Synthesis: Provides a stable, porous base for catalysts used in polymerization, dehydration, and other catalytic reactions.
Automotive: Used as a carrier in some automotive catalyst systems.
Key Advantage: Our alumina provides optimal pore structure, strong metal-catalyst binding, and resilience under high-temperature and high-pressure conditions, ensuring catalyst effectiveness and longevity.
