Recently, an Italian customer raised a specific technical application with us: Is there a product that can safely and efficiently remove peroxides from approximately 50 liters of ethanol with a peroxide content of 25 ppm, in order to protect its downstream pilot-scale membrane modules? Based on the data provided by the customer, Zibo Xiangrun proposed a solution: constructing an activated alumina pretreatment bed. Zibo Xiangrun specializes in the production of activated alumina and has activated alumina specifically developed for hydrogen peroxide.
Why Choose Activated Alumina for Hydrogen Peroxide Production?
Not all activated alumina is suitable for this precision process. Activated alumina for hydrogen peroxide production must meet extremely stringent requirements: Extremely low leachates: The activated alumina itself must be free of any impurities (such as Fe, Cu, etc.) that would dissolve in the working fluid and catalyze the decomposition of hydrogen peroxide.
Suitable pore structure and acidity: Optimized pore size distribution and moderate surface acidity are required to achieve efficient adsorption of moisture and alkaline impurities while avoiding adsorption loss of anthraquinone.
High mechanical strength: Ensures low wear and low pulverization during filling and long-term use, preventing system blockage.
Zibo Xiangrun's Alusorb XR107Q (DD6) hydrogen peroxide activated alumina possesses high strength and is insoluble in water, hydrocarbons, alcohols, oils, and other organic solvents. Even under the influence of water and alkalis, it will not turn into powder or soften. It is odorless, tasteless, non-toxic, has a long service life, exhibits a high degradation rate for anthraquinone derivatives, and possesses regenerative capabilities. It is a dedicated adsorbent for hydrogen peroxide in anthraquinone production. In addition to adsorbing alkaline substances, XR107Q (DD6) activated alumina balls can also efficiently adsorb degradation products generated during hydrogenation, reducing anthraquinone consumption and stabilizing the working fluid components.
The following are the data for Zibo Xiangrun's hydrogen peroxide-specific activated alumina:
Specifications: 7*14 mesh, 1/8”, 3/16”
AL2O3+ promoter: 93.5%
SiO2: 0.02%
Fe2O3: 0.02%
Na2O: 0.35%
Loss on ignition: 4-7
Bulk density (g/ml): 0.70-0.80
Surface area (㎡/g): 380
Pore volume (ml/g): 0.52
Absorption (%): 0.1
High alumina content and high purity mean more effective adsorption sites for decomposing peroxides and reduce the risk of impurities (such as Na₂O) leaching and contaminating the ethanol solvent. Low alkali metal oxide content reduces unnecessary side reactions in alcohol solvents, ensuring ethanol stability.
