Performance and use:
This product is γ-Al2O3, a white spherical particle made from the intermediate product of the quick stripping method. It has high strength, is insoluble in water and organic solvents such as hydrocarbons, alcohols, and fats, does not powder or soften in water and alkali, has high clarity, long service life, is odorless, and has strong degradation and regeneration capabilities for anthraquinone derivatives. It is a special adsorbent for the production of hydrogen peroxide by the anthraquinone method. It has been proven by many users that this product has a strong regeneration ability for hydrogenated degradation products in addition to adsorbing alkali in the working solution, and has a great effect on reducing the consumption of anthraquinone and stabilizing the components of the working solution. It is an ideal special adsorbent for hydrogen peroxide and has an excellent level among similar products in China.
