PROCESS FOR PRODUCING LOW WATER BIOMASS-DERIVED PYROLYSIS OIL

A process for preparing low-water biomass-derived pyrolysis oil is provided. The process comprises condensing pyrolysis gases in a condenser, drying the water-containing non-condensable pyrolysis gases, providing the reduced-water non-condensable pyrolysis gases to a pyrolysis reactor, pyrolyzing a...

Beschreibung
Zusammenfassung:	A process for preparing low-water biomass-derived pyrolysis oil is provided. The process comprises condensing pyrolysis gases in a condenser, drying the water-containing non-condensable pyrolysis gases, providing the reduced-water non-condensable pyrolysis gases to a pyrolysis reactor, pyrolyzing a biomass material in the pyrolysis reactor with the reduced-water non-condensable pyrolysis gases and condensing at least a portion of the reduced-water pyrolysis gases to form the low-water biomass-derived pyrolysis oil.
