Patent ID: 8519205

Claim:
A process for lowering water in a biomass-derived pyrolysis oil, comprising: i) condensing pyrolysis gases to separate condensable pyrolysis gases from water-containing non-condensable pyrolysis gases; ii) drying the water-containing non-condensable pyrolysis gases to reduce the water content of the water-containing non-condensable pyrolysis gases to form reduced-water non-condensable pyrolysis gases; iii) providing the reduced-water non-condensable pyrolysis gases to a pyrolysis reactor; iv) pyrolyzinq a biomass material in the pyrolysis reactor with the reduced-water non-condensable pyrolysis gases to form reduced-water pyrolysis gases; and v) condensing at least a portion of the reduced-water pyrolysis gases to form a low-water biomass-derived pyrolysis oil.
