Product Description
Activated alumina for hydrogen peroxide production is a high-purity alumina adsorbent specifically designed for adsorption and purification processes in hydrogen peroxide (H₂O₂) production. This product features a large specific surface area, a well-designed pore structure, strong adsorption capacity, and high mechanical strength. In hydrogen peroxide production systems, it effectively adsorbs impurities and degradation products from the working fluid, thereby maintaining system stability and improving production efficiency.
In industrial production, activated alumina is widely used in the anthraquinone process for hydrogen peroxide production. During recycling, the working fluid gradually produces organic degradation products and impurities. If these are not removed promptly, they will affect the hydrogen peroxide yield and product quality. High-performance activated alumina adsorbents specifically designed for hydrogen peroxide can selectively adsorb these impurities, helping to restore the activity of the working fluid and ensuring the long-term stable operation of the production unit.
This product is widely used in hydrogen peroxide production units, chemical purification systems, and fine chemical adsorption processes.

FAQ
Q:Why is activated alumina needed in hydrogen peroxide production?
A:During hydrogen peroxide production, the circulating working fluid produces degradation products, which can affect production efficiency. Activated alumina adsorbs these impurities, thus maintaining system stability.
Q:What is the difference between hydrogen peroxide-specific activated alumina and ordinary activated alumina?
A:Hydrogen peroxide-specific activated alumina typically has higher purity, a more optimized pore structure, and better chemical stability, making it more suitable for the anthraquinone process.
Q:How long can activated alumina be used?
A:The specific lifespan depends on process conditions and impurity content, but it can generally operate stably in the adsorption tower for extended periods.
Q:Can the particle size be customized?
A:Yes, we can provide products with different particle size specifications according to the customer's equipment requirements.
