ABSTRACT:
A system for decomposing aromatic hydrocarbons, such as furans, dioxins and PCBs, uses a glow discharge device as an electrochemical reactor. A gas, containing an aromatic hydrocarbon, is supplied at approximately atmospheric pressure to the glow discharge device which includes a pair of electrodes separated by a gap. The gas flows through the gap between the electrodes, one of which is preferably a planar electrode and the other of which is preferably a plurality of pins arranged perpendicular to the planar electrode. The electrodes are connected to a direct current power source via a ballast. The electrical potential across the electrodes is adjusted in conjunction with the flow rate to provide sufficient energy to break the benzene rings in the aromatic hydrocarbon, while preventing arcing across the electrodes.
