We all knowactivated aluminaIt is used as desiccant. Its color is pure white and will turn yellow after adsorption. However, many people do not know her adsorption principle. Let's take a look at Shengwell Environmental Protection
Activated alumina desiccant is a necessary product for the dehydration and drying of compressed air. In industry, activated alumina adsorption dryer is almost the only choice for the preparation of dry compressed air below zero pressure dew point. Before further research or correct use of activated alumina adsorption dryer, it is necessary to understand the adsorption principle and adsorbent.
Adsorption, also known as adsorption, is a natural phenomenon in which the molecular concentration of a substance changes automatically at two intersecting interfaces. The results show that adsorption occurs not only at the solid-gas interface, but also at the liquid-gas interface and the solid-liquid interface.
The adsorption system consists of an adsorbent and an adsorbate. A substance with a certain adsorption capacity is called an adsorbent, and the adsorbed substance is called an adsorbate. In the compressed air dryer, the commonly used adsorbents are silica gel, activated alumina and molecular sieve.
