Abstract

In the process for separating ammonia from gases, in particular exhaust gases from combustion processes, in which ammonia is formed or released, or in which ammonia or a substance forming ammonia under the action of heat is fed, a material from the group of the zeolites is added to the gas to be purified as a treatment medium in fine distribution, with good mixing with the gas. The added compounds here have the advantage that they not only remove the ammonia very effectively from the exhaust gases by adsorption but can also bind it very firmly in their internal structure, whereby renewed release of ammonia in permanent storage is avoided.
