The greater the polarity of molecular absorption, the easier the adsorption. Ethanol has a relatively strong polarity and is therefore adsorbed by molecular sieves. The 3A molecular sieve is a combination of an alkali metal silicate crystal and other special inorganic additives, and is formed into a

Activation temperature If it is necessary to completely remove the moisture adsorbed by the molecular sieve, it is preferably not more than 550 ° C under normal pressure, which is a general condition for determining the adsorption capacity of the molecular sieve. If the adsorbed moisture is industri

Activated alumina dryers are commonly used equipment for the removal of compressed air from water. Activated alumina adsorption dryers are almost the only choice in the industry when preparing dry compressed air below the zero dew point. Knowledge of the adsorption principle and adsorbent is necessa
