Determination of Adsorption Characteristics of Volatile Organic Compounds Using Gas Phase FTIR Spectroscopy Flow Analysis

Adsorption is an important operation for gas mixture separation and purification (Yang et al.1987). Thus, measurement of adsorption capacity is crucial for correct designing and operating of adsorption facilities. The heat of adsorption is also an important adsorption characteristic usually needed if adsorbent regeneration and/or adsorbate recovery is targeted (Do, 1998). Accurate knowledge of this thermodynamic parameter is of interest because the heat effects involved during adsorption and/or desorption may induce significant local warming to start combustion of either the adsorbate or the adsorbent itself, particularly, when activated carbon is used (EPA, 1998).
