ABSTRACT:
A process for recovering nitrobenzene, dichlorobenzene and/or trichlorobenzene from substantially undried exhaust gases or spent air containing these compounds, by passing said gases through a layer of silica-containing adsorbents and, after adsorption, regenerating the adsorbents by removing the sorbed compounds. The relative humidity of the waste vapors is preferably less than 50% in order to achieve an effective separation by adsorption.
