Abstract:
A process for producing H.sub.2 S from a sulfur, hydrogen and carbon containing feed in a molten metal bath comprising:a) forming a molten metal comprising at least 50 wt. % Fe;b) charging, at least periodically, a sulfur, hydrogen and carbon containing feed to said bath;c) thermally decomposing said sulfur, hydrogen and carbon containing feed to produce H.sub.2, H.sub.2 S and carbon;d) recovering H.sub.2 and H.sub.2 S as a vapor product from or above said molten metal bath;e) dissolving at least a portion of said carbon in said sulfur, hydrogen and carbon containing feed in said molten metal bath to form a molten metal bath containing at least 3 wt. % dissolved carbon;f) at least periodically adding oxygen or an oxygen containing gas to said molten metal bath to oxidize a portion of dissolved carbon from said bath, while limiting oxidation so that said bath contains at least 3 wt. % carbon at all times; andg) repeating steps b-f to process additional amounts of said sulfur, hydrogen and carbon containing feed.
