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.

Boehmite, also known as pseudoboehmite, is a transitional product with uncertain composition and incomplete crystallization, ranging from disordered to ordered, and from weakly crystalline to crystalline states. Its crystal structure is completely similar to boehmite, but the crystals are smaller and have poorer crystallinity, typically consisting of very thin, wrinkled lamellae. It possesses high specific […]
