Activated alumina

Activated alumina


Activated alumina is a porous substance with a large specific surface area, high mechanical strength, physical and chemical stability, high temperature resistance and corrosion resistance, and white particles. This product has high capacity and low wear,

The characteristics of strong water absorption capacity are widely used in the deep drying of various gas and liquid substances and the treatment of harmful impurities.

Application:

1. Under certain operating conditions and regeneration conditions, the drying depth of activated alumina is up to dew point -70 degrees or less. This product can be used as a defluorinating agent for high-fluorine drinking water (large defluorinating capacity) Alkane defluorinating agent,

Transformer deacid regeneration agent, used as gas drying in oxygen industry, textile industry, electronics industry, automatic instrument air drying, and as a drying and purifying agent in chemical fertilizer, petrochemical drying and other industries (dew point up to -40 degrees)

In the air separation industry, the pressure swing adsorption dew point can reach -55 degrees. It is a kind of highly effective desiccant for deep drying of trace water.

2. Special adsorbent for hydrogen peroxide production.

3. Suitable as a catalyst.

Packing: 25KG / piece. Can be specifically requested by customers
