Abstract
A system is described that includes a pyrolyzer and a primary condenser. The primary condenser is coupled to the pyrolyzer and configured to receive pyrolytic vapors from the pyrolyzer. The primary condenser is further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with a condensing liquid, to form a bio-oil component mixture having multiple separated phases. At least a portion of the condensing liquid includes a component that is extracted as a separated stable phase from a second bio-oil component mixture resulting from a prior pyrolysis cycle.

A pyrolysis system comprising:
- a pyrolyzer;
- a primary condenser, coupled to the pyrolyzer and configured to receive pyrolytic vapors from the pyrolyzer, and further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with a non-polar condensing liquid, to form a component mixture, such that the component mixture is phase separated into multiple separated phases, the component mixture including a non-polar bio-oil component originating from the pyrolytic vapors and a non-polar solvent component not originating from a pyrolysis process;
- wherein at least a portion of the non-polar condensing liquid comprises a fraction that is extracted as a separated stable phase from a second bio-oil component mixture resulting from a prior pyrolysis cycle.
A system for pyrolyzing material, the system comprising:
- a pyrolyzer;
- a primary condenser, coupled to the pyrolyzer and configured to receive pyrolytic vapors from the pyrolyzer, and further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with a non-polar condensing liquid, to form a bio-oil component mixture, such that the bio-oil component mixture is phase separated into multiple separated phases, the component mixture including a non-polar bio-oil component originating from the pyrolytic vapors and a non-polar solvent component not originating from a pyrolysis process;
- a capture vessel to receive the bio-oil component mixture;
- and
- a recirculator coupled to the capture vessel and the primary condenser, the recirculator configured to provide at least one of the multiple phases of the bio-oil component mixture as a second non-polar condensing liquid for use as at least a portion of the non-polar condensing liquid used in the primary condenser.
