METHOD FOR THE INTEGRATION OF CARBOCHLORINATION INTO A STAGED REFORMING OPERATION AS AN ALTERNATIVE TO DIRECT RESIDUE OXIDATION FOR THE RECOVERY OF VALUABLE METALS

摘要

Method of combining industrial processes having inherent carbon capture and conversion capabilities offering maximum flexibility, efficiency, and economics while enabling environmentally and sustainably sound practices. Maximum chemical energy is retained throughout feedstock processing. A hybrid thermochemical cycle couples staged reforming with hydrogen production and chlorination. Hydrogen generated is used to upgrade feedstocks including bitumen, shale, coal, and biomass. Residues of upgrading are chlorinated, metals of interest are removed, and the remainder is reacted with ammonia solution and carbon dioxide to form carbonate minerals. The combination provides emissions free production of synthetic crude oil and derivatives, as well as various metals and fertilizers. Sand and carbonate minerals are potentially the only waste streams. Through this novel processing, major carbon dioxide reduction is afforded byminimizing direct oxidation. Supplemental heat to run the reactions is obtained through external means such as concentrated solar, geothermal, or nuclear.

1. A method for the integration of carbochlorination into a staged reforming operation for the recovery of valuable metals from the byproduct stream, the method comprising:
i. a thermal decomposition stage or stages where feedstock is broken down through a plurality of thermochemical steps yielding a plurality of raw gas streams of varying composition to be combined into a synthesis gas and product gas as well as producing a solid residue consisting substantially of spent catalyst, inert minerals, and formed coke ii. a carbochlorination process hot-coupled to a steam methane reactor using molten metal compounds as a heat carrier between the exothermic carbochlorination and endothermic steam methane reforming wherein the raw gas streams are combined to form the appropriate stoichiometric proportions of hydrogen and carbon for the formation of synthesis gas to be consumed by downstream processeswhich integrated with any number of other relevant industrial processes, produce a product gas appropriate for any number of petrochemical and refinery operations including fuel suitable for a boiler, turbine, internal combustion engine, fuel cell, etc.
