Technical Field

Background

When gas contacts with the solid adsorbent, a phenomenon of containing gas, namely adsorption, occurs on the surface or inside of the solid. The adsorption process is divided into physical adsorption and chemical adsorption, wherein the physical adsorption mainly depends on intermolecular force (Van der Waals force), and the chemical properties of the adsorbent and the adsorbate are basically unchanged; chemisorption relies primarily on adsorbates to form chemical bonds with the adsorbent, which changes in chemical properties due to changes in the structure of the adsorption bonds.

The air separation molecular sieve regeneration (desorption) refers to regenerating an adsorbent after adsorption saturation, and recovering the adsorption capacity. There are two methods for regeneration, warming regeneration and depressurization regeneration. The heating regeneration utilizes the principle that the adsorption capacity of the adsorbent is reduced at high temperature, and heating gas is introduced into the adsorption layer, so that the temperature of the adsorption layer is increased, and adsorbed components are desorbed.
