Activated alumina balls can be used as desiccants in many industries and can effectively play a role. Activated alumina ball is a porous, highly dispersed solid material with a large surface area, and its microporous surface has the characteristics required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc. , so it is widely used as a catalyst and catalyst carrier for chemical reactions. It is non-toxic, odorless, non-pulverizing, and insoluble in water. . Under certain operating conditions and regeneration conditions, its drying depth is as high as the dew point temperature below -70°C, which is a trace water depth.
The principle of activated alumina ball desiccant is due to its own characteristics, and its drying principle is to physically adsorb water molecules in its own structure. Activated alumina desiccant is widely used in gas and liquid phase drying of petrochemical industry, drying of textile industry, oxygen production industry and automatic instrument air, pressure swing adsorption in air separation industry, etc. Due to the high net heat of the monomolecular adsorption layer, it is very suitable for a heatless regeneration device.
Precautions for the use of activated alumina:
(1) Do not open the package before use to avoid moisture absorption and affect the use effect.
(2) This product is suitable for deep drying, and the pressure should be greater than 5 kg/cm2.
(3) After the product is used for a certain period of time, the adsorption performance will gradually decrease, and the adsorbed water should be removed through regeneration, so that the gas used for regeneration operations can be used repeatedly.
