- both a gas and a dielectric liquid may be used.
- a cooling of the dielectric tube by a fluid can not be realized in a simple manner, since the energy input of the microwaves to the fluid heats the latter.
- Each additional heating of the fluid reduces the cooling effect on the dielectric tube.
- This reduction of the cooling capacity can also lead to a negative cooling capacity at high Mikrowellenabsorpti- on the fluid. This corresponds to an additional heating of the dielectric tube.
- the fluid In order to keep a heating of the fluid through the microwave low as possible, the fluid must at the wavelength of the microwaves a low dielectric loss tangent tan ⁇ in the range 10 -2 to 10 "have. 7 this way, a microwave power input is avoided in the fluid or to a Tolerable measure reduced.

- Such an arrangement is also particularly well suited for carrying out pure gas conversion processes such as exhaust gas purification or gas synthesis processes. Additional process gases can optionally be fed through further porous tubes of the process chamber.
