A process for the production of molecular hydrogen and demetallization of solid particles comprising: (a) contacting hydrogen sulfide at conditions effective to convert at least a portion of the hydrogen sulfide into molecular hydrogen, the contacting being conducted in the presence of solid particles comprising at least one metallic component effective to promote hydrogen sulfide conversion; (b) separating the molecular hydrogen from elemental sulfur formed in step (a) and unconverted hydrogen sulfide and recovering a product enriched in molecular hydrogen; and (c) demetallizing at least a portion of the solid particles from step (a) to produce demetallized solid particles having a reduced content of the metallic component.
