A reactor chamber forms part of an exhaust system of an internal combustion engine. Within the chamber are electrodes between which there is disposed a bed of active material through which, in use, the exhaust gases pass. In the presence of an electrical discharge, driven by an electrical voltage applied across the electrodes, the active material has a catalytic action in the reduction of nitrogenous oxides in the exhaust and also acts to remove hydrocarbons from the exhaust gases.

Treatment of gaseous emissions

A reactor () particularly for the plasma treatment of internal combustion engine exhaust gases, in which a power supply () and a reactor bed () of the dielectric barrier discharge type are connected directly and enclosed in an earthed metal chamber () which both isolates the high voltage power supply and acts as a Faraday cage preventing the emission of electromagnetic radiation from the power supply or plasma.

Power supply for processing of gaseous media

In a non-thermal plasma reactor (), at least a component of the active material () is selected or modified to provide the capability to adsorb or trap a predetermined chemical species in the gas flow thereby to increase the effective residence time of said species relative to the residence time of unadsorbed species in the gas flow.
