TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The system further comprises: means for separating and collecting entrained char from the exhaust gases, and means for feeding the portion of the separated char into the fast pyrolysis unit to produce additional heat and to assist in deoxygenation; the framework of vertical and horizontal structural members dimensioned to permit the system to be easily transported from one biomass source to another, where the fast pyrolysis unit is fitted with the framework of vertical and horizontal structural members; and the biomass feed bin, means for feeding the biomass from the feed bin into the fast pyrolysis unit, and means for passing the exhaust gases through the biomass to filter the exhaust gases. The system comprises means proximal to the second end of the outer pyrolysis chamber to capture and remove the exhaust gases.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further comprises: the step of separating and collecting entrained char from the exhaust gases, and step of channeling the separated char to a char bin for storage; the step of feeding a portion of the separated char into the fast pyrolysis unit to produce additional heat and assist in deoxygenation; the step of condensing bio-oil vapor entrained in the exhaust gases to a condensing temperature, and then collecting the bio-oil condensate; the steps of placing the biomass in a biomass feed bin, and the step of passing the exhaust gases separated from the entrained char and the entrained bio-oil vapor through the biomass in the biomass feed bin to filter the exhaust gases; and the steps of identifying a second sawmill location where quantities of biomass are generated, and then moving the fast pyrolysis unit to the second sawmill location. The method further comprises the steps of: feeding biomass generated at the second sawmill into the fast pyrolysis under pyrolytic reaction conditions; removing exhaust gases containing entrained matter resulting from pyrolytic reactions with the fast pyrolysis unit; separating and collecting bio-fuel entrained in the exhaust gases; and using at least a portion of the collected bio-fuel to power the second sawmill. The method further comprises the step of: fitting a capturing and channeling means proximal to the second end of the outer pyrolysis chamber to effectuate removal of the exhaust gases; mounting the fast pyrolysis unit within a framework of vertical and horizontal structural members which permit the unit to be easily transported between sawmills; and fabricating the fast pyrolysis unit so as to have a footprint permitting the unit to be mounted upon a flat bed truck.
