Definitions
- the invention relates to a method for converting gaseous, liquid and / or solid pollutants in pollutant-free or low-pollution decomposition products by the pollutants excited by means of a plasma, if necessary pre-decomposed or chemically converted and catalytic be decomposed.
- the pollutants For exhaust gas cleaning and treatment with toxic or harmful substances contaminated liquids or solids it is known to be the pollutants to convert plasma chemical into non-toxic decomposition products.
- the pollutants are, for example, in one thermal plasma (equilibrium plasma) burned, wherein the thermal plasma by ionizing a gas by applying a high-frequency electromagnetic field by means of a plasma torch, by electrical discharges or photon beams, generated by arcing or the like can be.
- the pollutant molecules in one cold plasma stimulate and by adding oxidizing agents or reducing agents excited by the plasma be transformed into harmless substances.
- Such cold plasmas are caused, for example, by glow discharges, silent discharges, corona discharges or by applying a high-frequency electromagnetic field Microwave generators generated under vacuum.

- at least one organometallic compound containing sulfur or at least one metal alcoholate containing sulfur can be added.
- the catalyst that can be activated by the plasma around a photocatalyst so is more preferred Execution provided that an electromagnetic radiation with a frequency in the range of the excitation frequency of the Plasma emitting photocatalyst is used, so that the plasma as a light source to activate the photocatalyst serves.
- the plasma at least one additive can be added, which by plasma excitation with electromagnetic radiation Frequency in the range of the excitation frequency of the photocatalyst emitted.
- Such additives are preferred from selected the group of noble gases, since these decompose the Do not negatively affect pollutants.
- auxiliaries can either oxidizing auxiliaries, e.g. Oxygen, be added the oxygen in this case, on the one hand, for oxidation the pollutants, on the other hand to form a photocatalyst serve in the form of one or more metal oxides can.
- auxiliary substances reducing the plasma e.g. Hydrogen added.
- a photocatalyst in the form of one or more Metal sulfides, for example, also as hydrogen sulfide Starting material used to form the photocatalyst become.
