How is activated alumina regenerated?
The activated alumina is referred to as "desorption" (or "regeneration") in order to release the adsorbate from the surface of the activated alumina so that the activated alumina adsorbent recovers its adsorption capacity. After the adsorbate is in sufficient contact with the activated alumina adsorbent, it will eventually reach dynamic equilibrium, and the amount of adsorbed reaches the maximum value (ie, saturation). “Dynamic equilibrium†refers to the adsorbed and desorbed adsorbate, the number of molecules is equal, at At equilibrium, the activated alumina adsorbent loses its adsorption capacity. Adsorption and resolution are in fact simultaneous, except that the amount of adsorption before saturation is greater than the amount of resolution. The activated alumina adsorbent loses its adsorption capacity after being saturated with the adsorbate, and should be regenerated to drive away the adsorbed moisture, acetylene and carbon dioxide, and then continue to use. Regeneration is the inverse process of adsorption—the analytical process. The regeneration is carried out by using the characteristics that the higher the adsorption temperature is, the lower the pressure is, and the smaller the adsorption capacity is. As the gas temperature increases, the molecular kinetic energy increases, and the activated alumina adsorbent does not adsorb the adsorbate, the adsorbate escapes. Therefore, regeneration is carried out at low pressure and high temperature. The regeneration temperature of the activated alumina adsorbent should be the temperature at which the adsorption capacity of the adsorbate is equal to zero, which is called complete regeneration. Acetylene, propylene and butane in the air can be purified to http://news.chinawj.com.cn before the adsorber is switched.
