Feedstock processing systems and methods for producing fischer-tropsch liquids and transportation fuels

A system for processing incoming feedstock to selectively recover biogenic carbon material from the incoming feedstock, the system comprising:

• a sorting station configured to separate the incoming feedstock into a first stream containing mixed solid waste material having a predetermined size and larger, and a second stream containing mixed solid waste material having the predetermined size and smaller;
• a first size reduction unit in communication with the sorting station and configured to comminute the first stream to produce an output stream containing mixed solid waste having the predetermined size and smaller, and combine the output stream and the second stream to produce a combined stream;
• a fractionation unit in communication with the first size reduction unit and configured to fractionate the combined stream by size to remove small size, low carbon content material having a size of 2 inches and smaller from high carbon content material;
• a fine fractionation density unit in communication with the fractionation unit and configured to further fractionate the high carbon content material to remove inert material to produce a carbonaceous material stream;
• a ferrous removal unit in communication with the fine fractionation density unit configured to remove ferrous material from the carbonaceous material stream;
• a non-ferrous removal unit in communication with the ferrous removal unit and configured to remove non-ferrous material from the carbonaceous material stream;
• a plastic removal unit in communication with the non-ferrous removal unit and configured to remove plastic material from the carbonaceous material stream;
• a second size reduction unit in communication with the plastic removal unit and configured to comminute the carbonaceous material stream to produce an output stream containing carbonaceous material having a size of 1 inch and smaller;
• and
• a drying unit in communication with the second size reduction unit and configured to dry the output stream containing carbonaceous material having a size of 1 inch and smaller to produce a processed feedstock containing carbonaceous material and a moisture content in a range of 8% to 15%.
