Hello Roland, Thank you for the information about your process. Is your process a "slow" pyrolysis reaction?
If so the bio- oil is a substantially different product then the "fast" pyrolysis oil that some companies are trying to convert to motor fuel . Am I correct that you are combusting this oil for thermal energy and not attempting to run a motor ? Are you making an aqueous phase also? If so, are you finding use for this "wood vinegar" ? I have a gasification/ pyrolytic hybrid that I built and can make a slow pyro oil in my process. I am currently pouring the oil onto some of the feedstock going into the gasifier and boosting my fuel btu ( and getting rid of that oil).
