Reducing pollutant gases in gas mixtures from pyrotechnic reactions

The invention relates to a method, agents and a device for reducing pollutant gases in gas mixtures resulting from pyrotechnic reactions. To this end, at least one additive from the group of metallocenes, metallocene derivatives, urea, urea devivatives, sulphur and/or sulphur compounds is vaporized...

Beschreibung
Zusammenfassung:	The invention relates to a method, agents and a device for reducing pollutant gases in gas mixtures resulting from pyrotechnic reactions. To this end, at least one additive from the group of metallocenes, metallocene derivatives, urea, urea devivatives, sulphur and/or sulphur compounds is vaporized during the pyrotechnic reaction, as a result of the temperature released during said reaction. The pollutant gases are converted into non-toxic compounds in a homogenous gas phase reaction.
