Abstract

The direct decomposition of hydrogen sulfide into hydrogen and sulfur was studied in a dielectric barrier discharge plasma reactorwith an inner electrode made of a stainless steel rod that was later replaced with a modified sintered metal fibers to introduce catalystinside the plasma zone. The feasibility of DBD plasmolysis for the hydrogen production by H 2 S decomposition was assessed. Typicalresults indicate that H 2 selectivity is ~100% throughout the range of present study. The influence of several parameters like thedischarge gap between the electrodes, residence time of the gas in the discharge zone, the applied voltage and the effect of catalysthave been studied to find the optimal process conditions.
