Annotation:
Gas adsorption drying is one of the most important technological processes in the production of liquefied natural gas, field processing of natural gas for pipeline transportation, chemical processing of gases and in petroleum chemistry. The paper presents the results of studies aimed at determining the conditions of thermal regeneration of zeolite-containing adsorbents that differ in the type of zeolite. It is found that to restore the adsorption activity of zeolite adsorbents in the drying of gases, thermal regeneration is advisable to be carried out at temperatures of 250…330 °C and duration of at least 100 minutes.
