Application of activated alumina
Application of activated alumina
Activated alumina is widely used in many industries. The following are some specific industries and their main uses:
1. Petrochemical industry:
Catalyst carrier: Activated alumina is often used as a catalyst carrier, such as for catalytic cracking, dehydrogenation, desulfurization and other reactions. In these processes, the high specific surface area and pore structure of activated alumina enable it to provide good catalytic activity and selectivity, thereby improving the efficiency of the reaction and the purity of the product.
Adsorbent: In the field of petrochemicals, activated alumina is also used as an adsorbent to remove harmful substances in gases and liquids, such as hydrogen sulfide, organic solvents, etc.
2. Environmental protection field:
Wastewater treatment: Activated alumina can be used for wastewater treatment. Through adsorption and catalytic oxidation, organic matter and heavy metal ions in wastewater are removed to achieve the purpose of purifying water quality.
Waste gas treatment: Activated alumina can adsorb and decompose harmful substances in waste gas and reduce the emission of pollutants.
3. Fine chemical industry:
Catalyst: Activated alumina is one of the important components of catalysts and is widely used in petrochemicals, chemical pharmaceuticals, organic synthesis and other fields. It can be used as a carrier to carry different types of catalyst metals, such as platinum, cobalt, etc., to improve the activity and selectivity of the catalyst.
Adsorbent: In fine chemicals, activated alumina is also used as an adsorbent to adsorb and remove various harmful substances.
4. Drinking water treatment:
Activated alumina can remove odor, color, organic matter, etc. in water and improve the taste of drinking water. It is especially suitable for defluoridation of drinking water in high-fluorine areas.
5. Other fields:
Activated alumina can also be used as a filler material for the preparation of various high-efficiency thermal insulation materials and high-pressure performance plastics.
In the metal smelting industry, activated alumina can be used as an oxidant and a reducing agent.
Activated alumina is also widely used in the textile industry, oxygen production industry, and the drying of automated instrument air, pressure swing adsorption in the air separation industry, etc.
In summary, activated alumina plays an important role in many industries such as petrochemicals, environmental protection, fine chemicals, and drinking water treatment with its high surface area, good adsorption performance and high temperature stability. With the continuous development of science and technology, the application prospects of activated alumina will be broader.
