Opis:
This paper concerns the atmospheric-pressure microwave plasmas and their applications, mainly for gas processing. Several types of atmospheric-pressure microwave sources (MPSs), i.e. surface-wave-sustained MPS, nozzle-type MPSs, nozzleless MPSs, plasma-sheet MPSs and microwave microplasma sources - MmPSs (antenna- and coaxial-line- -based) as well as their performance are presented. The presented experimental results on the optimization of selected MPSs are confronted with results of the modelling of the electromagnetic field in them. The paper deals also with the applications of MPSs for the processing of gases. Two types of the plasma gas processing were experimentally tested: decomposition of volatile organic compounds (VOCs) and reforming of VOCs (mainly methane) into hydrogen. Results of the laboratory experiments on the plasma processing of several highly-concentrated (up to 100%) VOCs, including freon-type refrigerants, in the waveguide-supplied MPSs showed that the microwave discharge plasma is capable of fully decomposing the VOCs at relatively low energy cost. The use of waveguide-supplied coaxial-line-based and metal-cylinder-based nozzleless MPSs to methane reforming into hydrogen turned out to be energetically efficient. These selected results show MPSs to be an attractive tool for gas processing, including the harmful gas decomposition and production of useful gases.

Opis:
The hydrogen production by conversion of liquid compounds containing hydrogen was investigated experimentally. The waveguide-supplied metal cylinder-based microwave plasma source (MPS) operated at frequency of 915 MHz at atmospheric pressure was used. The decomposition of ethanol, isopropanol and kerosene was performed employing plasma dry reforming process. The liquid was introduced into the plasma in the form of vapour. The amount of vapour ranged from 0.4 to 2.4 kg/h. Carbon dioxide with the fl ow rate ranged from 1200 to 2700 NL/h was used as a working gas. The absorbed microwave power was up to 6 kW. The effect of absorbed microwave power, liquid composition, liquid fl ow rate and working gas fl ow rate was analysed. All these parameters have a clear infl uence on the hydrogen production effi ciency, which was described with such parameters as the hydrogen production rate [NL(H2)/h] and the energy yield of hydrogen production [NL(H2)/kWh]. The best achieved experimental results showed that the hydrogen production rate was up to 1116 NL(H2)/h and the energy yield was 223 NL(H2) per kWh of absorbed microwave energy. The results were obtained in the case of isopropanol dry reforming. The presented catalyst-free microwave plasma method can be adapted for hydrogen production not only from ethanol, isopropanol and kerosene, but also from different other liquid compounds containing hydrogen, like gasoline, heavy oils and biofuels.
