Abstract
A pyrolysis apparatus and pyrolysis method are provided. The pyrolysis apparatus comprises a microwave generator, a waveguide which is coupled to the microwave generator and in which a standing wave can be generated, and a fluid pipe, through which a fluid can be guided in a fluid guidance direction transverse to the direction of propagation of the standing wave. A pyrolysis cell, in which the fluid is acted upon by the standing electromagnetic wave, is formed in the fluid pipe. In order to achieve a high rate of degradation of molecules to be pyrolysed, the pyrolysis cell is limited in the direction of an outlet by a metal grid.
Claims29
Pyrolysis method for pyrolysing a fluid, comprising;
- generating a standing electromagnetic wave;
- guiding a fluid to be pyrolysed through a fluid pipe in a fluid guidance direction transversely to a direction of propagation of the standing electromagnetic wave;
- forming a microwave plasma in the fluid within a pyrolysis cell of the fluid pipe and disassociating corresponding molecules of the fluid as a result of the fluid being acted upon in the pyrolysis cell by the standing electromagnetic wave;
- and
- preventing formation of a discharge dent in areas of the fluid pipe having a low electromagnetic energy density;
- wherein:
- said areas of the fluid pipe having a low electromagnetic energy density are outside of said pyrolysis cell;
- and
- the formation of the discharge dent outside of the pyrolysis cell is prevented by arranging a first metal grid and a second metal grid in spaced relationship in the fluid guidance direction in the pyrolysis cell, a mesh aperture of the first metal grid and the second metal grid being smaller than half a wavelength of the standing electromagnetic wave.
