ABSTRACT OF THE DISCLOSURE Removal of mercury from mercury vapour-containing gases by passing them continuously through a bed of active carbon on which a halogen is adsorbed having a thickness of at most 5 cm, while maintaining the chlorine content of the active carbon between 5 and 12% by weight. This is preferably effected by adding to said gases chlorine in an amount such that the carbon is caused to absorb a quantity thereof which equals the quantity that is con-sumed during the adsorption of mercury. |
