Yuanjiang Brand - Activated Alumina DesiccantThe product appears as white spherical particles, featuring strong adsorption capabilities, a large specific surface area, high compressive hardness, and a long service life. It can be reused through regeneration methods. It is odorless, tasteless, and non-toxic. It exhibits moisture absorption in the air, and when absorbing water, it does not swell or crack, maintaining its original shape. It has adsorption effects on gases such as NOX, F2, and AS. This product is widely used in instrument air drying in industries such as petrochemicals, chemicals, textiles, and metallurgy, as well as in pressure swing adsorption air separation units, where the adsorption dew point can reach below -41°C. It is also suitable for deep drying of liquid and gas phases in steel, petroleum cracking gas, ethylene, and propylene.
