Methods for forming a carbon molecular sieve includes loading polymer fibers into a mold and heating the mold containing the polymer fibers to a temperature in a range from 50 ° C. to 350 ° C. to form a polymer monolith. The polymer monolith is then pyrolized by heating to a temperature in a range from 500 ° C. to 1700 ° C. A carbon molecular sieve monolith includes a first end and a second end opposite the first end, and carbon molecular sieve fibers aligned in parallel from the first end of the carbon molecular sieve monolith to the second end of the carbon molecular sieve monolith. Channels extend from the first end of the carbon molecular sieve monolith to the second end of the carbon molecular sieve monolith, and outer surfaces of the carbon molecular sieve fibers are joined. The carbon molecular sieve monolith has a cell density of greater than 500 cells per square inch.

This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas 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.
