    Abstract: An NOx reducing exhaust treatment system includes a non-thermal plasma reactor assembly which initiates NOx reduction reactions that are completed by a catalytic converter downstream of the reactor in the system. The reactor assembly includes a monolithic reactor element formed of insulating plates and spacers made of high dielectric material, such as alumina. Some of the plates carry electrodes and connecting conductors which may be painted on with conductive ink and baked on as a surface coating. The electrodes are patterned to provide a distance between the electrodes and the connectors of alternate electrodes that is sufficient to prevent arc over. The plates and spacers form a plurality of thin gas passages each lying between a pair of electrodes, one to be charged with an AC voltage and the other grounded to impress the alternating voltage across each passage. The electrodes are insulated from the passages by the thin insulating plates forming the passages so that no current flows between the electrodes. Instead, the voltage creates a non-thermal plasma in the passages that increases the activity of electrons in the exhaust gases and initiates breakdown of the NOx and other reaction products in the gases. The reactions are then completed in a downstream catalytic converter, resulting in reduced emissions of NOx as well as other controlled emissions in the treated exhaust gases.

    Abstract: A simplified, low cost method for preparing a non-thermal plasma reactor comprises forming cell building blocks of material having a high dielectric constant, printing a conductive print onto the cell walls, assembling the cells into a multi-cell stack, providing electrical connections for connecting said cells to a high voltage source, applying insulation to said multi-cell stack, and inserting the multi-cell stack into a non-thermal plasma reactor housing. The simplified design eliminates the need for spacers between individual cells, thus reducing the total number of components. The method employing formed shape building blocks provides flexibility and may be used in conjunction with conventional processing methods. The printing sequence is defined from the top of the multi-cell stack to the bottom, further minimizing the number of components. Use of a three-dimensional conductive print further simplifies preparation by eliminating the need for a secondary conductive print along the edge of the stack.

The segmented elements may comprise a variety of shapes, such as C-shaped elements, I-shaped elements, planar elements, swept-shaped elements, inter-digitized elements prepared from comb-shaped elements.
