Activated alumina, with its excellent mechanical strength, reliable drying depth, and good anti-interference ability, provides the best balance of performance and cost in most industrial applications. Ensuring good pre-filtration and regular maintenance is key to fully realizing its performance and extending its service life. How does activated alumina work in a dryer? In the most […]
With the rapid development of the global chemical industry, hydrogen peroxide, as an important green oxidant, is increasingly being used in fields such as environmental protection, electronics, textiles, and medicine. In the production of hydrogen peroxide, activated alumina, as a key catalyst carrier, plays an irreplaceable role. The core role of activated alumina in hydrogen […]
Pseudoboehmite is an incompletely crystallized boehmite with a unique layered structure, high porosity, and a large specific surface area. It typically appears as a white or slightly yellow paste or powder. Its most significant value lies in its ability to be converted into various activated aluminas, such as γ-Al₂O₃ and η-Al₂O₃, after calcination at specific […]
In industrial gas processing, compressed air purification, and many chemical processes, “deep drying” is a crucial step. Among numerous adsorbent materials, activated alumina desiccant has become one of the most widely used and trusted choices due to its outstanding performance. So, why is activated alumina so efficient? How does activated alumina desiccant work? Its working […]
一. Why is alumina the preferred catalyst support? 1. High Surface Area: Alumina (especially the γ-type) offers a surface area of up to hundreds of square meters per gram, providing a vast dispersion platform for active metal components, maximizing exposure of active sites and improving atomic utilization efficiency. 2. Adjustable Surface Acidity: Alumina surfaces possess […]
In the world of cryogenic air separation, where extreme precision is crucial, the purity and dryness of incoming air cannot be compromised. Even trace amounts of water vapor can form ice blockages in heat exchangers and distillation columns, leading to serious equipment failure. This is where a robust front-end purification system becomes the first line […]
In the field of catalyst materials, alumina has become one of the most commonly used carriers in industrial catalysis due to its high specific surface area, excellent thermal stability and controllable surface acidity. From oil refining to environmental protection, from chemical production to new energy development, alumina carriers support many key chemical reactions with their […]
In many parts of the world, excessive fluoride levels in drinking water pose a serious public health problem. Long-term consumption of high-fluoride water can lead to diseases such as dental fluorosis and skeletal fluorosis. Meanwhile, fluoride-containing wastewater generated by industries such as semiconductors, glass, and electroplating also faces stringent discharge standards. Among numerous defluorination technologies, […]
