Abstract

Patente de Invenção: <B> "REDUçãO DE GASES POLUENTES EM MISTURAS DE GáS RESULTANTES DE REAçõES PIROTéCNICAS"<D>. A invenção refere-se a um processo, agentes e um dispositivo para a redução de gases poluentes em misturas de gases resultantes de reações pirotécnicas, que são realizadas pelo fato de que por ocasião da reação pirotécnica, ao menos um aditivo do grupo dos metalocenos, derivados de metalocenos, uréia, derivados de uréia, enxofre e/ou compostos de enxofre, é evaporado por meio da temperatura que é liberada da reação pirotécnica e os gases poluentes são convertidos em uma reação de fase gasosa homogênea em compostos não-tóxicos.Invention Patent: <B> "REDUCTION OF POLLUTING GASES IN MIXTURES OF GAS RESULTING FROM PIROTECHNICAL REACTIONS" <D>. The invention relates to a process, agents and a device for reducing polluting gases in gas mixtures resulting from pyrotechnical reactions, which are carried out by the fact that at the time of the pyrotechnic reaction, at least one additive from the group of metallocenes, derivatives of metallocenes, urea, derivatives of urea, sulfur and / or sulfur compounds, is evaporated through the temperature that is released from the pyrotechnic reaction and the polluting gases are converted into a homogeneous gas phase reaction in non-toxic compounds.
