A pyrolysis auger advances pyrolyzing biomass from the chamber inlet end to the chamber outlet end. The inner pyrolysis chamber, inner heating elements, pyrolysis auger, outer pyrolysis chamber and outer heating elements are generally concentric. A biomass feed extruder advances biomass orthogonally into the pyrolysis chamber.

Systems, apparatus and methods for optimizing the pyrolysis of biomass using thermal expansion
A process for pyrolyzing biomass comprises pyrolyzing cellulosic biomass in a fast pyrolysis chamber by heating the cellulosic biomass to a pyrolyzation temperature to generate a pyrolysis vapor flow therefrom. The pyrolysis vapor flow is directed from the fast pyrolysis chamber along a vapor flow conduit to a condensation trap at a temperature sufficient to condense the vapor to liquid and generate a thermal gradient along the vapor flow conduit between the pyrolysis chamber and condensation trap. A majority of the pyrolysis vapor flow along the vapor flow conduit to the condensation trap is achieved by natural convection. Systems that can practice this process are also disclosed.

Apparatus, system, and method for producing bio-fuel utilizing concentric-chambered pyrolysis
An apparatus, system, and method for subjecting biomass to pyrolysis to extract energy products using a pyrolysis unit comprising generally concentric chambers including a combustion chamber and at least one pyrolysis chamber. Each chamber is in communication with an adjacent chamber such that a directed, generally-deoxygenated heated gas stream passes through the combustion chamber to each of the pyrolysis chambers in turn. Additionally, each pair of adjacent chambers shares a heat-conducting wall, further promoting heat transfer throughout the unit. A heat source, which can be a burn enclosure configured as part of the pyrolysis unit, produces the heated gas stream. Biomass introduced into the pyrolysis unit is pyrolysized by the gas stream, resulting in exhaust containing non-condensing gases, bio-oil vapor, and entrained char. The exhaust is directed from the pyrolysis unit to other parts of the system where the bio-oil and char can be separated from the exhaust and collected.
