What is the difference between silica alumina gel and activated alumina?
Silica alumina gel is a kind of silica gel containing aluminum oxide, pore-resistant water-resistant silica alumina gel, which is generally used as a protective layer for fine pore silica gel and fine pore silica alumina gel, and also used separately during high content of liquid water.
In the case of liquid water in the operating system, a low dew point can also be achieved with Silica alumina gel.
Silica alumina gel is mainly used for air drying in air separation process, acetylene adsorption in liquid oxygen and liquid nitrogen preparation, drying of compressed air and various industrial gases, and liquid adsorbent and catalyst carrier in petrochemical, electric, brewing and other industries. Used as a protective layer for ordinary silica gel and silica alumina gel.
Activated alumina---The use of alumina in the catalyst is commonly referred to as "activated alumina", which is a porous, highly dispersible solid material with a large surface area and a microporous surface with the properties required for catalysis, such as it is widely used as a catalyst for chemical reactions and a catalyst carrier because of its adsorption properties, surface activity, excellent thermal stability and the like.
The spherical activated alumina pressure swing oil adsorbent is white spherical porous particles, the activated alumina has uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling and no cracking after being absorbed, and is non-toxic, odorless and insoluble. Water, ethanol. Activated alumina is a highly effective desiccant for the deep drying of trace water and is suitable for use in non-thermal regeneration units.
