    Abstract: This disclosure relates to the fast pyrolysis of organic matter. More specifically, it relates to the catalytic modification of vapors created during the fast pyrolysis of organic matter to create transportation fuel or a transportation fuel component. At least a first portion of pyrolysis vapors is catalytically stabilized or converted, then combined with a portion of raw, unconverted bio-derived pyrolysis vapors at a temperature and pressure sufficient for molecules of the combined vapors to react and produce hydrocarbons of increased molecular weight that are suitable for use as a hydrocarbon transportation fuel or component thereof.

    Abstract: The present disclosure relates generally to a two-stage biomass pyrolysis processes that maximize pyrolysis vapor yield from a lignocellulosic biomass while being conducive to commercial-scale throughput of biomass. A lignocellulosic feedstock is first pyrolyzed in a reactor first stage comprising at least one auger at a temperature and residence time that produces pyrolysis vapors derived predominantly from cellulose and hemi-cellulose fractions of the feedstock. Partially-pyrolyzed feedstock from the reactor first stage is then pyrolyzed in a reactor second stage at a higher temperature for an additional residence time to produce additional pyrolysis vapors that are predominantly derived from lignin. Certain embodiments arrange multiple reactor first stages around a single reactor second stage.

    Abstract: This disclosure relates to systems for the fast pyrolysis of organic matter. More specifically, it relates to systems for the catalytic modification of vapors created during the fast pyrolysis of organic matter to create transportation fuel or a transportation fuel component. The inventive systems either catalytically stabilize or convert at least a first portion of pyrolysis vapors, then combine them with a portion of raw, unconverted bio-derived pyrolysis vapors at a temperature and pressure sufficient for molecules of the combined vapors to react and produce hydrocarbons of increased molecular weight that are suitable for use as a hydrocarbon transportation fuel or component thereof.
