Abstract: A method for processing feedstock is described, characterized in that incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock. In some embodiments the incoming feedstock is comprised of mixed solid waste, such as municipal solid waste (MSW). In other embodiments the incoming feedstock is comprised of woody biomass. In some instances, the incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% and greater suitable for conversion into biogenic carbon Fischer Tropsch liquids. The high biogenic carbon Fischer Tropsch liquids may be upgraded to biogenic carbon liquid fuels. Alternatively, the incoming feedstock is processed to selectively recover plastic material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% or less.

Abstract: Jet boiling range compositions are provided that include at least a portion of an isoparaffinic blend component, along with a method for making such a blend component. The highly isoparaffinic nature of the blend component can allow the isoparaffinic blend component to be used in combination with both conventional/mineral jet fuel boiling range fractions as well as non-traditional feeds (such as Fischer-Tropsch fractions) to form jet fuel fractions and/or jet fuel blending component fractions.

Abstract: A method of producing liquid fuel and/or chemicals from a carbonaceous material entails combusting a conditioned syngas in pulse combustion heat exchangers of a steam reformer to help convert carbonaceous material into first reactor product gas which includes carbon monoxide, hydrogen, carbon dioxide and other gases. A portion of the first reactor product gas is transferred to a hydrogen reformer into which additional conditioned syngas is added and a reaction carried out to produce an improved syngas. The improved syngas is then subject to one or more gas clean-up steps to form a new conditioned syngas. A portion of the new conditioned syngas is recycled to be used as the conditioned syngas in the pulse combustion heat exchangers and in the hydrocarbon reformer. A system for carrying out the method include, a steam reformer, a hydrocarbon reformer, first and second gas-cleanup systems, a synthesis system and an upgrading system.

Abstract: Processes for using pyrolysis gas as a feedstock or a co-feedstock for making a variety of chemicals, for example, circular ethylene, circular ethylene polymers and copolymers, and other circular products. In these processes, pyrolysis reactor conditions can be selected to increase or optimized the production of pyrolysis gas over pyrolysis oil, and the pyrolysis gas which is usually used as fuel or flared can be fed downstream of the steam cracker furnace for economic use to form circular chemicals. Operating parameters of the pyrolysis unit may be adjusted to increase or decrease the proportion of pyrolysis gas relative to pyrolysis liquid as a function of their relative economic values.
