Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from municipal solid wastes (MSW) feedstocks

A system for producing syngas derived from municipal solid wastes (MSW) processed feedstock that contain biogenic carbon, said system comprising:

• a bio-refinery for converting the MSW processed feedstock into syngas, the bio-refinery comprising:
• an input stream containing MSW processed feedstock that has been processed to remove non-biogenic derived carbon materials and non-carbonaceous materials from the MSW to produce MSW processed feedstock that contains a greater concentration of biogenic carbon than non-biogenic carbon;
• a gasification island (GI) configured to receive the input stream and gasify, sub-stoichiometrically oxidize and hydrocarbon reform the MSW processed feedstock to produce syngas containing CO, H2, H2O and CO2 from the MSW processed feedstock;
• a syngas conditioning unit configured to receive syngas from the gasification island and remove contaminants, remove/recover CO2 and provide CO2 for recycle that contains a greater concentration of biogenic carbon than non-biogenic carbon;
• a CO2 recycle stream that recycles the CO2 from the syngas conditioning unit to the gasification island for biogenic carbon conservation and adjusts H2:CO2 ratio in the syngas to a predetermined value;
• and
• a power generator that receives syngas containing a greater concentration of biogenic carbon than non-biogenic carbon and converts some or all of the syngas into power;
• wherein the gasification island further comprises:
• a steam reformer, the steam reformer containing an indirect heating apparatus inside the steam reformer, and configured to dry, volatilize and gasify the processed feedstock to produce (i) a first syngas stream containing CO, H2, H2O and CO2, and unreacted hydrocarbons, and (ii) a stream of solids comprising ash and unreacted char;
• a sub-stoichiometric carbon oxidation unit configured to receive the stream of solids and gasify the unreacted char from the stream of solids to produce a second syngas stream, the second syngas stream joining the first syngas stream to form a third syngas stream and maximize the quantity of biogenic carbon in the MSW processed feedstock;
• and
• a hydrocarbon reforming unit configured to receive the third syngas stream and convert any remaining char, hydrocarbons and tars into syngas by thermal dissociation.
