High Mechanical Strength And Wear Resistance Activated Alumina For Hydrogen Peroxide(H2O2)
Activated alumina is a leading hydrogen peroxide-specific adsorbent. Activated alumina is γ-Al2O3, using intermediate in the speedy dewatering process as raw materials to make white pellets. It is high strength, non-soluble in water, hydrocarbons, alcohol, grease and other organic solvents. It doesn’t become powder and soft in water and alkali. It is odorless, tasteless, non-toxic, long life and high degradation of anthraquinone derivatives and regeneration ability. Activated alumina is a specific adsorbent of hydrogen peroxide(H2O2) in anthraquinone production. Excepting alkali adsorption, activated alumina balls highly adsorb the degradation of hydrogenation, reduce the consumption of anthraquinone and stabilize working fluid components.
Technical index of activated alumina
|Activated Alumina Desiccant Typical Physical Properties|
|Crush Strength||N ≥||150||180||200||230|
|Specific Surface Area||m2/g||300-330|
|Attrition Rate||wt% ≤||0.1|
|Static Water Adsorption||wt% ≥||18|
|The interval value of the indexes above are on the basis of the different grade of Activated Alumina Desiccant|
· Activated Alumina Desiccant cannot be exposed in the open air and should be stored in dry condition with air-proof package
· Activated Alumina Desiccant should be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°C
