PYROLYSIS SYSTEM AND METHOD FOR BIO-OIL COMPONENT EXTRACTION

摘要

A system is described that includes a pyrolyzer and a primary condenser. The primary condenser is coupled to the pyrolyzer and includes an input to receive pyrolytic vapors from the pyrolyzer and a solvent. The condenser is further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with the solvent to form a condensed liquid that exits the primary condenser via an output. A capture vessel receives the condensed liquid from the condenser output. A recirculator couples the capture vessel to the primary condenser input and is configured to receive the condensed liquid from the primary condenser, and to provide at least a portion of the condensed liquid as the solvent in the primary condenser. The solvent from the bio-oil component/solvent mixture is then extracted in a solvent extraction system and returned to the quenching system.
