For Hydrogen Peroxide
Activated Alumina for H2O2
中文名：双氧水用活性氧化铝
Molecular formula: Al2O3·nH2O (0<n≤0.8)
Molecular weight: 102-117
This product is white, spherical porous material and is non-toxic, odorless, tasteless. It is insoluble in water, esters, hydrocarbons, alcohols and other organic solvents. It has long life, not powdering and softening in water and alkali, is a special adsorbent for anthraquinone production of hydrogen peroxide.
Besides adsorbing alkali in the working fluid, it also has strong reproductive property to the hydrogenation breakdown products, and the increase of degradation products in the hydrogenation reaction can be converted into the active anthraquinone, which can ensure the stability of the total effective amount of anthraquinone, and is conducive to the oxidation reaction, so it can reduce the amount of anthraquinone added, saving the running cost.
Considered the regeneration, this product guarantees the good machine capability, and the active changes small after regeneration.
