Abstract
A process is provided for recycling heterogeneous waste including the initial step of subjecting the heterogeneous waste to pyrolysis to produce a synthesis gas stream comprising at least carbon monoxide and hydrogen and a molten pyrolysis product stream having a variable composition comprising at least a mineral material and a metallic material. The molten pyrolysis product stream is converted to a plurality of commercial grade solid materials. Likewise, the synthesis gas stream is also converted into at least one commercial grade chemical.
Claims18
A process for recycling heterogeneous waste comprising the steps of:
- subjecting the heterogeneous waste to pyrolysis to produce a synthesis gas stream comprising at least carbon monoxide and hydrogen and to produce a molten pyrolysis product stream having a variable composition comprising at least a mineral material and a metallic material;
- converting said molten pyrolysis product stream to a plurality of commercial grade solid materials;
- and
- converting said synthesis gas stream into at least one commercial grade chemical;
- wherein said molten pyrolysis product conversion step includes the steps of:
- allowing said molten pyrolysis stream to gravitationally segregate into metallic portion and a mineral portion;
- separating said metallic portion from said mineral portion;
- quenching said metallic portion of said molten pyrolysis product stream to form a metallic alloy;
- and
- quenching said mineral portion of said molten pyrolysis product stream to form a vitreous material.
A process for producing methanol from heterogeneous waste comprising the steps of:
- subjecting the heterogeneous waste to pyrolysis to produce a synthesis gas comprising hydrogen and carbon monoxide and to produce a molten pyrolysis product stream;
- sensing the ratio of hydrogen and carbon monoxide within said synthesis gas;
- adjusting the ratio of said hydrogen and carbon monoxide components of said synthesis gas to a ratio of approximately 1.95:1 to 20:1 molecules of hydrogen per molecule of carbon monoxide;
- and
- presenting said adjusted synthesis gas to a liquid phase methanol reactor for producing methanol,
- wherein said molten pyrolysis product stream is converted to a plurality of commercial grade solid materials by the steps of:
- allowing said molten pyrolysis stream to gravitationally segregate into metallic portion and a mineral portion;
- separating said metallic portion from said mineral portion;
- quenching said metallic portion of said molten pyrolysis product stream to form a metallic alloy;
- and
- quenching said mineral portion of said molten pyrolysis product stream to form a vitreous material.
