Claim Text:
1. A gas processing apparatus, comprising: a first and a second dielectric substrate facing with each other; a first and a second discharge electrode respectively disposed on a pair of facing principal surfaces of the dielectric substrates; a first and a second ground electrode respectively disposed on a pair of principle surfaces at opposite sides of the principle surfaces of the dielectric substrates; a gas port downstream of a gas inlet port configured to add an addition gas including a hydrogen element to atmosphere, an object gas including at least one of carbon element and nitrogen element, and oxygen gas, forming a gas mixture; a gas flow path configured to supply the gas mixture between the first and second discharge electrodes; an AC power source configured to generate a first plasma-induced flow at a first discharge electrode side and a second plasma-induced flow at a second discharge electrode side by, applying an AC voltage between the first discharge electrode and the second discharge electrodes and the ground electrodes to ionize the mixture the first and the second plasma-induced flows including OH radical formed from the oxygen gas and the addition gas; and a region disposed between the dielectric substrates at downstream of the plasma-induced flows from the first and second discharge electrodes, and a gap between the dielectric substrates being 2 mm or more and 6 mm or less, wherein the object gas in the gap is decomposed by the OH radical.
