ABSTRACT
Adsorption on activated carbon is one of the most widely used processes in air treatment. After describing the mechanisms of transfer and adsorption of molecules in a gaseous phase onto a solid surface, adsorbents, and especially activated carbon, are presented. Different technologies are described according to their industrial applications: type of gaseous effluent to be treated (volatile organic compounds, odors, etc.), concentrations and flows. Regeneration methods are also discussed.
