Abstract
Organic waste is treated in a molten metal bath to sequentially form enriched hydrogen gas and carbon oxide gas streams. The method includes introducing organic waste to a molten metal bath in the absence of a separate oxidizing agent and under conditions that will decompose the organic waste. As a consequence of this decomposition, an enriched hydrogen gas stream is generated and the molten metal bath becomes carbonized. Thereafter, an oxidizing agent is added to the carbonized molten metal bath to oxidize the carbon contained in the carbonized molten metal bath. Reaction of the oxidizing agent with the carbon causes formation of a carbon oxide that escapes from the bath as an enriched carbon oxide gas stream, thereby decarbonizing the molten metal bath.
