Abstract
The disclosure relates to systems and methods to produce hydrogen (H2) gas from hydrogen sulfide (H2S). H2S is contacted with a catalyst to form H2 gas and sulfur adsorbed to the catalyst. The adsorbed sulfur is contacted with oxygen (O2) gas to convert the adsorbed sulfur to sulfur dioxide (SO2) and regenerate the catalyst.
Claims12
A method, comprising:
- a) contacting hydrogen sulfide with a catalyst to form hydrogen gas and sulfur adsorbed to the catalyst;
- and
- b) contacting the adsorbed sulfur with oxygen to convert the adsorbed sulfur to sulfur dioxide, thereby regenerating the catalyst.
