Abstract

A system and corresponding process for treating biomass, including by use of a plurality of pyrolysis treatment steps. The process can be used to provide a first pyrolysis product (e.g., intermediate), in the form of a carbon enriched material that contains substantially less hemicellulose content than the initial biomass, while substantially retaining and optionally enriching cellulose and/or lignin content as compared to the initial biomass. The process also includes a second pyrolysis device, adapted to further pyrolyze the first pyrolysis product in order to provide one or more gasses and/or vapors (e.g., providing condensable or non-condensable bio-products) and solid ash byproduct. The process also permits gasses and/or vapors that are generated in the course of its operation to be used in a variety of ways, including by: (a) recycling the gas/vapor into the system, in order to faciliate pretreatment (drying) of biomass, (b) condensing and recovering the gas/vapor or components thereof, and (c) venting or otherwise disposing of the gas/vapor.
