  • Patent number: 6258988
    Abstract: A method is disclosed for reforming organics into shorter-chain unsaturated organic compounds. A molten metal bath is provided which can cause homolytic cleavage of an organic component of an organic-containing feed. The feed is directed into the molten metal bath at a rate which causes partial homolytic cleavage of an organic component of the feed. Conditions are established and maintained in the reactor to cause partial homolytic cleavage of the organic component to produce unsaturated organic compounds, as products of the homolytic cleavage, which are discharged from the molten metal bath.

  • Patent number: 5695732
    Abstract: A method relates to treating a halogenated organic waste to produce halogen gas and carbon oxide gas streams. The method includes directing a halogenated organic waste, having a halogen-to-hydrogen atomic ratio of less than about one, into a molten metal bath. The molten metal bath is inert to the halogen and has a free energy of oxidation greater than that of the formation of carbon monoxide from atomic carbon. The halogenated organic feed is converted into halogen gas and atomic carbon, whereby the halogen gas is released from the molten metal bath. An oxidant is directed into the molten metal bath, whereby the atomic carbon is oxidized to form a carbon oxide gas, which is released from the molten metal bath.

  • Patent number: 5537940
    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.
