How to select the appropriate adsorbent under different process conditions
Thread Content
We all know that the common adsorbents used in pressure swing adsorption are silica gel, activated carbon, alumina, and molecular sieves. Molecular sieves are generally chosen for hydrogen purification, while activated carbon is used for carbon removal... Under different process conditions, how should one select the appropriate adsorbent, and why? Please explain in more detail. Thank you... This post was last edited by Tongrenju on 2008-1-3 14:21.]
It is mainly based on the properties of the substance being processed! ! !
Based on the separation coefficient and adsorption capacity of the adsorbent for the components of the substances to be separated
There are many books on the principles of adsorption. There are also many successful cases of industrial adsorption devices; you can look for information on that topic online. The selection of an adsorbent always depends on the components of the mixture, concentrations, temperature, pressure, as well as the desired product. In fact, the most basic principle is to select an appropriate adsorbent by using the sum of the most reasonable investment and operation costs.
