Abstract: The invention relates to a method for removing mercury from flue gases of high-temperature plants, in particular of power plants and waste incineration plants, in which method bromine and/or compounds containing bromine are added to the flue gas after firing in the flow direction. The flue gas is then subjected to at least one dry scrubbing process to remove the mercury and perhaps excessive bromine and/or excessive bromine compounds. The method according to the invention is characterized in that the bromine and/or the bromine compounds are brought in contact with the flue gas at a flue gas temperature ranging from 80° C. to 490° C., preferably from 80° C. to 250° C.

Abstract: The invention concerns a process for the production of carbonaceous adsorption agents doped with elementary sulfur, in which sulfur is mixed with the adsorption agent, the mixture is heated to a temperature of between 120° C. and 150° C. and the temperature is maintained over a period of about an hour. The process is distinguished in that heating of the mixture is effected under a controlled oxygen-bearing atmosphere. The invention further concerns a process for waste gas cleaning using carbonaceous absorption agents doped with elementary sulfur. Preferably brown coal coke is used as the adsorption agent.

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.
