NOVELTY - Production and upgrading of pyrolysis product, comprises: pyrolyzing biomass feedstock (12) in first reactor comprising at least one auger (22) that conveys feedstock through reactor from first end towards second end, where pyrolyzing forms primary pyrolysis products comprising primary gaseous product (37) and char; passing primary gaseous product through first outlet at or near top of first reactor and to upgrading reactor (40); and contacting primary gaseous product with upgrading catalyst (42) in upgrading reactor that is isolated from contact with char.    USE - The process is useful for production and upgrading of a pyrolysis product (claimed) including a mixture of hydrocarbons fungible with petroleum-derived fuels including gasoline, jet-fuel, diesel and gasoil.    ADVANTAGE - The process: provides protection and thus extension of the lifespan of the downstream upgrading catalysts by preventing contact between the catalysts and the char generated during pyrolysis of the biomass feedstock, while simultaneously minimizing the time between production of the pyrolysis vapors and subsequent upgrading, thus maximizing upgradability of the vapors to fuels; and utilizes the pyrolysis reactor comprising auger which assists in rapidly and evenly distributing heat to the feedstock, as well as helping to convey the feedstock through the pyrolysis reactor.    DETAILED DESCRIPTION - Production and upgrading of a pyrolysis product, comprises: pyrolyzing a biomass feedstock (12) in a first reactor comprising at least one auger (22) that conveys the feedstock through the reactor from a first end towards a second end, where the pyrolyzing forms primary pyrolysis products comprising a primary gaseous product (37) and char; passing the primary gaseous product through a first outlet at or near the top of the first reactor and to an upgrading reactor (40); and contacting the primary gaseous product with an upgrading catalyst (42) in the upgrading reactor that is isolated from contact with the char, where the primary gaseous product does not condense prior to the contacting and comprises compounds containing less than 16 carbon atoms.    DESCRIPTION OF DRAWING(S) - The figure shows a simplified diagram of depicting a pyrolysis reactor with a catalyst vessel to receive and upgrade the vapors from the pyrolysis reactor.
