| Popis: | The process of hydrogen sulfide, H 2 S, dissociation with oxygen addition was studied in a gliding arc plasma discharge. The goal of the study was to develop a plasma process that could demonstrate increased H 2 S conversion, reduced specific energy requirement (SER), and similar H 2 yield when compared with plasma dissociation of pure H 2 S. The minimum SER of H 2 production was found to be 1.0 eV/molecule at atmospheric pressure, 14 L/min H 2 S and 2.8 L/min O 2 flow rates, and specific energy input (SEI) of 0.29 eV per H 2 S molecule. At the same conditions, the minimum SER of H 2 S destruction was found to be 0.43 eV/molecule, while hydrogen yield was observed to be 27%, water production was observed to be 38%, H 2 S destruction was observed to be 65%, and no measureable SO 2 was detected. These results confirm the ability to reduce energy cost for H 2 production while increasing H 2 S destruction in the system without sacrificing production of H 2 . This is very desirable from an industrial standpoint, where the processing and recycling of H 2 S is a very costly process. |
