Processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Pyrolysis in the presence of an inert gas is employed to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.

A distillation apparatus for use in microwave-assisted pyrolysis includes a microwave, a pyrolysis reactor, a microwave-absorbent bed, and a condenser. The pyrolysis reactor is located within the microwave and configured to receive a liquid input stream and to output a vapor. The microwave-absorbent bed is located within the pyrolysis reactor that converts microwave energy provided by the microwave to thermal energy to initiate pyrolysis within the pyrolysis reactor, wherein the pyrolysis reactor provides a vapor output. The condenser is configured to receive the vapor output of the pyrolysis reactor and to cool and condense the vapor into a recoverable product.
