- Summary:
- There are four post combustion (nonthermal) plasma treatments on the table for reducing NOx in exhaust streams. This paper compares these techniques and suggests what appears to be a novel (8 inventions) and optimum path for development of auseful ehaust treatment system. We propose to use 5 GHz microwaves which will have a risetime of 20 ps, 100 times shorter than present state of the art and result in the best chemistry path by reduction ofplasma shielding, greater availability of atomic nitrogen, elimination of surface charging of dielectrics, avoidance of low threshold fields, and higher breakdown limit. We also propose combining a surface intrinsically into the plasma discharge. Novel embodiments are proposed for the pebbel bed discharge allowing an order of amgnitude increase of eidl-volume over the closest packing configuration.
