1. A process for producing a high-carbon biogenic reagent, the process comprising:
providing a carbon-containing feedstock comprising dry biomass;
preheating, in a preheating zone, the feedstock in the presence of a substantially inert gas, thereby generating a preheated feedstock;
pyrolyzing, in a pyrolysis zone, the preheated feedstock in the presence of a substantially inert gas, thereby generating 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;
cooling, in a cooling zone, the hot pyrolyzed solids, in the presence of the substantially inert gas and with a cooling temperature less than the pyrolysis temperature, thereby generating warm pyrolyzed solids;
cooling, in a cooler that is separate from the cooling zone, the warm pyrolyzed solids, thereby generating cool pyrolyzed solids; and
recovering a high-carbon biogenic reagent, wherein the high-carbon biogenic reagent comprises at least a portion of the cool pyrolyzed solids;
wherein the process further comprises introducing at least one additive into the process.
