Abstract
The present invention features methods and apparatus for the pyrolysis or torrefaction of a carbon-containing feedstock before it is converted to syngas. In some embodiments, biomass is first pretreated by torrefaction and/or pyrolysis, followed by devolatilization and/or steam reforming to produce syngas. Various mixtures of such pretreated biomass, combined with fresh biomass, can be employed to produce syngas. The syngas can be converted to alcohols, such as ethanol, or to other products.
Claims20
An apparatus for producing syngas comprising a pyrolysis or torrefaction reactor in communication with a devolatilization unit that is in communication with a heated reaction vessel.
An apparatus for producing syngas comprising a pyrolysis or torrefaction reactor in communication with a device for combining a pyrolyzed or torrefied first feed material with a second feed material that has not been pyrolyzed or torrefied, wherein the device is in communication with a syngas reactor for converting the first feed material and the second feed material into syngas.
An apparatus for producing syngas comprising a pyrolysis or torrefaction reactor in communication with a devolatilization unit that is in communication with a heated reaction vessel.
