Title:
METHODS AND APPARATUS FOR ENHANCING THE ENERGY CONTENT OF CARBONACEOUS MATERIALS FROM PYROLYSIS
Document Type and Number:
WIPO Patent Application WO/2012/142488
Kind Code:
A3
Abstract:
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.
