At least three-step molten metal decomposition process cycle

Year	Description
1999	Invention patented by Donald P. Malone on May 17th, 1999. Abstract: Sequential processing of hydrogen rich and hydrogen deficient feeds (14 and 16) in a heat balanced, single molten metal bath (40) to produce both 90+ mole % hydrogen (90) and one or more lower purity vapor streams (140) is disclosed. The molten metal bath is heated by oxygen addition (18) to burn dissolved carbon from the bath and then cooled by sequential addition of two feeds with differing hydrogen contents. Preferably a 98% hydrogen product with a pressure of at least 2 atm., absolute is obtained, along with a lower purity hydrogen containing stream and a separate carbon oxides flue gas stream.
