NOVELTY - The pyrolyzer system comprises a first screen (20), a second screen (18), a catalyst material positioned between the first and second screens, a condenser, an absorber, and a separation unit. The pyrolyzer system is structured such that feedstock is pyrolyzed in an inert gas atmosphere adjacent to the first screen, where gas generated by pyrolysis is drawn through the first screen, the catalyst material and the second screen. The catalyst is retained in a bowl (10) structured so that the first and second screens are located near a top and a bottom of the bowl.    USE - The pyrolyzer system is useful for generating bio-oil (claimed) that is useful as a refinery feedstock for the production of renewable transportation fuels and for analysis and aging studies, where the pyrolyzer system is a fast pyrolysis catalytic cracking pipe.    ADVANTAGE - The pyrolyzer system ensures rapid generation of large quantities of bio-oil with high quality.    DETAILED DESCRIPTION - The pyrolyzer system comprises a first screen (20), a second screen (18), a catalyst material positioned between the first and second screens, a condenser, an absorber, and a separation unit. The pyrolyzer system is structured such that feedstock is pyrolyzed in an inert gas atmosphere adjacent to the first screen, where gas generated by pyrolysis is drawn through the first screen, the catalyst material and the second screen. The catalyst is retained in a bowl (10) structured so that the first and second screens are located near a top and a bottom of the bowl. The bowl is jacketed by a heater (22). The first screen, the bowl, the heater, the catalyst and the second screen comprise a cracking pipe. The gas is drawn downwardly and upwardly through the cracking pipe. The heater pre-heats the catalyst to fast pyrolysis temperatures. The inert gas atmosphere is maintained by a shroud (24) disposed around the cracking pipe. The feedstock is directly heated by a torch (28) that is an oxyfuel torch positioned above the first screen. The gas is directed horizontally out of the cracking pipe. A flow of the gas out of the cracking pipe is modulated by a vacuum source. The flow of the gas is modulated by a manual valve or an automated solenoid valve. Temperature within the cracking pipe is controlled by a temperature control system. The temperature control system monitors the cracking pipe temperature through a thermocouple. The thermocouple is co-located with the valve. The gas from the cracking pipe is directed to and through the condenser and the absorber. The condenser comprises an impingement condenser that comprises a single condenser tube immersed in a cold water bath. The absorber comprises an absorber column structured so that the gas enters the absorber column. Absorber fluid is sprayed into the absorber column so that absorber fluid and/or a product bio-oil collect in a reservoir associated with the absorber column. The separation unit is adapted for separating the product bio-oil from the absorber fluid. An INDEPENDENT CLAIM is included for a method for generating bio-oil.
