1. A process for producing a high-carbon biogenic reagent, the process comprising:
providing a carbon-containing feedstock comprising biomass;
in a pyrolysis zone, pyrolyzing the feedstock in the presence of a substantially inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases;
separating at least a portion of the condensable vapors and at least a portion of the non-condensable gases from the hot pyrolyzed solids;
in a cooling zone, cooling the hot pyrolyzed solids, in the presence of the substantially inert gas with a cooling-zone temperature less than the pyrolysis temperature, to generate warm pyrolyzed solids;
in a cooler that is separate from the cooling zone, cooling the warm pyrolyzed solids to generate cool pyrolyzed solids;
recovering a high-carbon biogenic reagent comprising at least a portion of the cool pyrolyzed solids; and
forming a fine powder from the high-carbon biogenic reagent.
