Claim Text:
1. A method for processing a gas, wherein the method comprises: employing an elongated vessel with an inner space of cylindrical symmetry, wherein the elongated vessel: injecting the gas that is to be processed such that the gas forms a first vortex flow running along an inner wall of the inner space of the elongated vessel and reflects from the bottom wall at the second end to form a second vortex flow of the gas that is to be processed running along a center axis of the elongated vessel from the bottom wall and out the exit channel at the first end, and forming a standing microwave in the microwave chamber aligned to form a wave crest at the center axis of the elongated vessel in an area of the elongated vessel that is transparent to microwave energy capable to excite at least a portion of the gas in the second vortex to form a microwave non-thermal plasma.
