Production of molecular hydrogen via thermal decomposition of hydrogen sulfide and separation of hydrogen and hydrogen sulfide by pressure swing adsorption.
Preferable conditions for the thermal decompn. of H2S, one stage in the thermochem. water splitting cycles of metal-S families, are described. To sep. H2 from H2S after condensation of S a pressure-swing adsorption on zeolite or carbon mol. sieves is proposed which may also be suitable for sepg. H2S from other gas mixts. such as natural gas and noble gas.
