adsorbent

Commonly used adsorbents are : silica gel, alumina, activated carbon, molecular sieve and other adsorbents. The adsorption performance of the adsorbent for various gas components was evaluated by experimentally measuring the isothermal adsorption line under static conditions and the breakthrough curve under dynamic conditions. The good adsorption performance of the adsorbent is the basic condition for the adsorption separation process. In the process of pressure swing adsorption, the contradiction between adsorption and desorption should be considered in the selection of adsorbent. On the one hand, the adsorbent should have a large adsorption capacity for impurities. On the other hand, the adsorbed impurities should be easily desorbed to achieve adsorption and desorption equilibrium in a short period, so that the separation and purification process can be maintained. Another key point in selecting an adsorbent is that the separation coefficient between the components is as large as possible. The larger the separation coefficient of the gas component, the easier the separation, and the higher the purity of the product gas. At the same time, the higher the recovery rate. The separation of gas mixtures with complex components and many categories often requires the selection of several adsorbents. These adsorbents can be layered in the same adsorption bed according to the adsorption separation performance, and in some cases, they can also be filled in each adsorption bed separately. Because of the above reasons, the pressure swing adsorption process has special requirements for the adsorbent, so we call the adsorbent used in the pressure swing adsorption process as a special adsorbent. The pressure swing adsorbent developed by our company has high recovery rate and long service life. Welcome to inquire.
