Abstract

This disclosure provides a method of making a high-fixed-carbon material comprising pyrolyzing biomass to generate intermediate solids and a pyrolysis vapor; condensing the pyrolysis vapor to generate pyrolysis liquid; blending the pyrolysis liquid with the intermediate solids, to generate a mixture; and further pyrolyzing the mixture to generate a high-fixed-carbon material. A process can comprise: pyrolyzing a biomass-comprising feedstock in a first pyrolysis reactor to generate a first biogenic reagent and a first pyrolysis vapor; introducing the first pyrolysis vapor to a condensing system to generate a condenser liquid; contacting the first biogenic reagent with the condenser liquid, thereby generating an intermediate material; further pyrolyzing the intermediate material in a second pyrolysis reactor to generate a second biogenic reagent and a second pyrolysis vapor; and recovering the second biogenic reagent as a high-yield biocarbon composition. The process can further comprise pelletizing the intermediate material. Many process and system configurations are disclosed.
