Abstract:
1. An integrated process for the provision of fuel for zero-emission power generation, metallurgical reduction, and carbon oxides management to mitigate greenhouse gases, comprising: providing a source of each of steam, oxygen gas, and chlorine gas, gasifying a carbonaceous source using said steam and oxygen, and producing a gaseous hydrogen output and a gaseous carbon monoxide output; performing carbochlorination on an ore containing a plurality of metallic components using said chlorine gas as a reactant and said gaseous carbon monoxide as an oxygen sink, producing from said carbochlorination a heterogeneous output stream containing a plurality of metal chlorides corresponding to carbochlorination of said plurality of metallic components, and a gaseous carbon dioxide output; processing said heterogeneous output stream in a manifold fluidized bed reactor (MFBR) and segregating said plurality of metal chlorides into a plurality of homogeneous metal chloride output streams and a byproduct carbon dioxide stream, each homogeneous metal chloride stream corresponding to one of said plurality of metallic components, passing said plurality of homogeneous output streams into a corresponding plurality of containers, each container containing a segregated metal chloride; and managing said gaseous carbon monoxide and carbon dioxide generated by said gasifying and carbochlorination steps, comprising: passing said carbon monoxide output from said gasifying step to said carbochlorination step as said oxygen sink; converting said gaseous carbon dioxide output from said carbochlorination step into a methane pool augmentation output, an elemental carbon output, and a chemical synthesis output; consuming said elemental carbon output in a manufacturing process; and consuming at least a first portion of said gaseous hydrogen output in a power generator step, and consuming a second portion of said gaseous hydrogen output in a chemical synthesis process; wherein said integrated system is essentially free of greenhouse gas emissions; wherein the emissions of said power generator step are essentially free of greenhouse gasses.
