Biomass Bio Oil Upgrade Method

摘要

A bio oil pyrolysis and conditioning system produces a useful fuel oil. The pyrolysis system includes an auger carrying biomass feed material though an oxygen rare pyrolysis chamber. Vapor phase bio oil is collected at three locations along the length of the pyrolysis chamber and carried from the pyrolysis chamber to condensers and quenched by a water spray before release into the condensers. The water also serving as a solvent to reduce pH in the liquid phase raw bio oil. The raw bio oil is carried to a conditioning system where the raw bio oil resides in a separation tank where the water separates and is removed producing refined bio oil. Ethanol is mixed with the refined bio oil to provide the fuel oil.

主权项

1. A method for producing a useful bio oil material, the method comprising:
feeding biomass into a pyrolysis chamber; heating the biomass to create vapor phase bio oil; carrying the vapor phase bio oil to a condenser; condensing the bio oil vapor into liquid phase raw bio oil in the condenser; separating water from the raw bio oil in a separator to produce refined bio oil; and processing the refined bio oil into a useful material.
