Synthesis of aluminum-oxide adsorbents using alkalis at the hydration stage and study of their physicochemical and adsorptive properties

Abstract

The paper presents the research results of physicochemical characteristics, adsorption kinetics and value of adsorption capacity with respect to water vapors of the aluminum-oxide adsorbent modified with potassium and sodium cations. It was shown that modification of desiccants by potassium and sodium cations at the hydration stage of products of hydrargillite thermal activation during synthesis allowed obtaining adsorbents-desiccants with high values of static (more than 20 g/100g) and dynamic capacitance (more than 5.0 g/cm3) by water vapors.
