Abstract
The production of hydrogen from CH 4 :CO 2 :H 2 S (70%:30%:1000ppm) mixture, simulating dry biogas in a DBD reactor, supplied with nanosecond negative pulses, is presented. We have found that sulphur produced from H 2 S during the process changes the electrical parameters of the reactor with a RVC electrode. As a result, the production of syngas and the selectivity of methane conversion into hydrogen, decreases. Due to changed electrical parameters of the reactors, radicals formed from methane recombine into C 2 and C 3 hydrocarbons more efficiently, resulting in lower production of hydrogen. Major by-product of the methane processing is propane, concentration of which is comparable to hydrogen.
