Hydrogen peroxide (H₂O₂) is an important chemical product widely used in paper bleaching, wastewater treatment, the electronics industry, and chemical synthesis. During industrial production, the purity and stability of hydrogen peroxide largely depend on the performance of the purification and adsorption system. During the production cycle, the working solution may contain trace organic impurities, decomposition […]
What Is Activated Alumina for Hydrogen Peroxide? Activated alumina for hydrogen peroxide is a high-performance adsorbent specifically developed for hydrogen peroxide (H₂O₂) production processes. It is mainly used in working solution purification, impurity adsorption, and product refining during hydrogen peroxide manufacturing. It effectively removes organic degradation products, trace impurities, and catalytic decomposition by-products, helping maintain […]
Characteristics of Normal Pseudo Boehmite Normal Pseudo Boehmite features a high specific surface area and excellent forming properties, making it one of the most widely used alumina precursor materials in the industry today. Key Features High specific surface area Small and uniformly distributed pore size Excellent shaping and forming performance High mechanical strength Relatively low […]
Activated alumina plays a vital role in protecting molecular sieves, reducing air dew points, and ensuring the stable operation of Air Separation Units (ASUs). However, the performance of activated alumina varies significantly among different manufacturers. Focusing only on price during procurement may result in lower adsorption efficiency, higher operating costs, and even affect the safety […]
What Is Activated Alumina? Activated alumina is a highly porous aluminum oxide (Al₂O₃) adsorbent with a large surface area, excellent adsorption capacity, and superior mechanical strength. It is widely used in drinking water purification, industrial wastewater treatment, air separation units, natural gas dehydration, and many other applications. In water treatment, the most significant advantage of […]
Why are alumina ceramic balls required for waste gas treatment equipment? In waste gas purification systems, catalysts, adsorbents, and reaction media typically need to be secured within the reactor. Without a stable support layer, catalysts are prone to collapse, abrasion, or loss due to factors such as continuous gas flow, high-temperature operation, and thermal stress […]
Selecting high-quality activated alumina not only improves dehydration efficiency but also reduces operating costs and extends equipment service life. So, what exactly are the characteristics of high-quality activated alumina desiccant? 1. High adsorption capacity for superior dehydration efficiency Adsorption capacity is a key indicator of activated alumina performance. High-quality activated alumina features a well-developed pore […]
I. Observing Color Changes Observing color changes is one of the most intuitive methods for determining whether potassium permanganate-impregnated activated alumina requires replacement. Fresh potassium permanganate-impregnated activated alumina typically appears purplish-red or deep purple; this coloration is due to the potassium permanganate loaded onto its surface. During the process of adsorbing and oxidizing harmful gases, the potassium […]
In modern hydrogen peroxide production, a variety of other adsorbents—such as silica gel, molecular sieves, and activated carbon—are also available on the market for use in similar processes. This paper presents a comparative analysis of activated alumina versus these adsorbents, examining them across three key dimensions: performance, application, and cost, with the aim of assisting […]
In processes involving compressed air drying, air separation, natural gas dehydration, and industrial gas purification, the dew point serves as a critical metric for assessing the dryness of a gas. When selecting an adsorbent, many users face a common dilemma: which material—activated alumina or molecular sieves—is the right choice? Activated Alumina: Dew Point Capabilities Activated […]
