In the anthraquinone process for producing hydrogen peroxide, the purity of the working solution is crucial. During recycling, the working solution degrades, producing moisture and alkaline impurities. These impurities not only accelerate the further degradation of anthraquinone and reduce hydrogenation efficiency, but more seriously, they directly lead to the decomposition and instability of the hydrogen peroxide product. Activated alumina is the core material for purifying the working solution, and its performance directly affects production efficiency, product purity, and operational safety.
The core function of activated alumina in hydrogen peroxide production is selective adsorption, primarily removing two key types of impurities:
1. Deep dehydration: Activated alumina efficiently adsorbs trace amounts of water dissolved in the working solution, ensuring the system remains absolutely dry. This is fundamental to preventing hydrogen peroxide decomposition in subsequent processes.
2. Removal of alkaline impurities: It effectively adsorbs and neutralizes alkaline substances such as organic acids produced during the degradation of the working solution, restoring the chemical balance of the solution, protecting anthraquinone, and fundamentally improving the yield and stability of hydrogen peroxide.
Why Choose Activated Alumina Specifically Designed for Hydrogen Peroxide?
Not all activated alumina is suitable for this precision process. Activated alumina for hydrogen peroxide production must meet extremely stringent requirements: Extremely Low Leachables: 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.
