Dissociation of H2S in non-equilibrium gliding arc “tornado” discharge

The process of hydrogen sulfide, H2S, dissociation was studied in a non-equilibrium gliding arc “tornado” (GAT) plasma discharge. Utilizing GAT ensured uniform H2S gas treatment in the reactor. In addition, it created a low temperature zone near the cylindrical wall of the reactor, while maintaining a high temperature zone near the reactor axis. An energy cost of 1.2 eV per H2 molecule was achieved in this plasma system at atmospheric pressure. These results are particularly important for the oil industry, which consumes large amounts of hydrogen in oil hydro-treatment, and for gas industry because of the high H2S content in “sour” gas.
