The equilibrium adsorption capacity of acetone vapor on silica–alumina was about four times higher than that of toluene vapor because of polarity difference between adsorbent and adsorbate. As inlet concentration and linear velocity were increased, MTZ (mass transfer zone) and LUB (length of unused...
Adsorption can be defined further based on the strength of the interaction between the adsorbent (the substrate onto which chemicals attach) and the adsorbed molecules. Physisorption— Van der Waals interactions between substrate and adsorbate (the molecule that is adsorb...
