Properties, Use and Preparation of Activated Alumina
1. Properties of Activated Alumina1.1 Specific Surface AreaIn theory, the specific surface area of alumina can be as high as 360 m2/g if the sintering system of alumina is reasonably controlled. However, the pore size of activated alumina prepared by

Difference between Alkaline Alumina and Acidic Alumina
Alkaline alumina surface tends to retain positive charges or hydrogen bonds. Alumina pretreated with alkaline solution has anionic properties and cation exchange function. It can be retained to electron sample such as neutral amines, which is much we

Meaning of Technical Indicators of Hollow Glass Molecular Sieves
Static water adsorption (wt%): at a certain relative temperature and humidity, the larger the static water adsorption capacity, the better the molecular sieve quality; only when the relative humidity is low, the adsorption capacity can show the depth

Detailed Explanation of Molecular Sieve Regeneration Curve
The regeneration curve of zeolite starts to decrease from pressure relief, but the starting temperature of heating should increase slightly and then gradually increase until the end of heating.At the beginning of pressure relief, s
