Patent ID: 7767166

Claim:
A radial flow non-thermal plasma reactor for treating a gas, comprising: a tubed shaped housing with an input end and an output end; a central channel within the housing, operable to receive the gas from the input end; a first electrode screen bounding the outside of the central channel and operable as a high voltage electrode; a first inner channel concentric with the central channel, operable to receive the gas after the gas flows radially through the first electrode screen; wherein the first inner channel is a non-thermal plasma reactor comprising a dielectric and/or non catalytic material; a second electrode screen bounding the outside of the first inner channel and operable as a ground electrode; a second inner channel concentric with the first inner channel, operable to receive the gas after the gas flows radially through the second electrode screen; wherein the second inner channel comprises a catalytic material that is operable to react with radicals activated in the first inner channel; a third screen bounding the outside of the second inner channel and not acting as an electrode; an outer channel operable to receive the gas after the gas flows radially through the third screen, and further operable to channel the gas to the output end of the housing.
