Abstract

Sorbent for the dry cleaning of waste gases charged with mercury and process for the production thereof. The sorbent includes as an adsorptively acting constituent for example activated carbons or activated cokes which are mixed with sulfur in powder form at ambient temperature, under the action of atmospheric oxygen. The sorbent is distinguished by a given ratio in respect of the median values of the grain size of the adsorptively operative constituent to the sulfur.
