Abstract

In decomposing noxious gases, liquids and/or solids (I) into harmless decomposition products by plasma excitation, optional pre-decomposition or chemical reaction and catalytic decomposition, an active catalyst (II) is formed in situ in the plasma and (I) and/or the decomposition products are decomposed completely on (II). In decomposing noxious gases, liquids and/or solids (I) into (almost) harmless decomposition products by plasma excitation, optional pre-decomposition or chemical reaction and catalytic decomposition, starting material(s) for the formation of active catalyst (II) under the plasma conditions is added to the plasma continuously, (II) is formed in situ in the plasma and (I) and/or the decomposition products are decomposed completely on (II).
