  • Devices and Methods for a Pyrolysis and Gasification System for Biomass Feedstock
    Publication number: 20220106528
    Abstract: A pyrolysis and gasification system produce a synthesis gas and bio-char from a biomass feedstock. The system includes a feed hopper that has a flow measurement device. The system also includes a reactor that is operable in a gasification mode or a pyrolysis mode. The reactor is configured to receive the biomass feedstock from the feed hopper. The reactor is operable to provide heat to the biomass feedstock from the feed hopper to produce the synthesis gas and bio-char. The system also includes a cyclone assembly. The produced synthesis gas including the bio-char is fed to the cyclone assembly. The cyclone assembly removes a portion of the bio-char from the synthesis gas.

  • Devices and Methods for a Pyrolysis and Gasification System for Biomass Feedstock
    Publication number: 20130205727
    Abstract: A pyrolysis and gasification system and method convert a biomass feed stock to bio-char and synthesis gas. In one embodiment, the pyrolysis and gasification system includes a reactor for producing a synthesis gas and bio-char from a biomass feedstock. The system includes a flow measurement device and an air distribution system, which provides a fluidized bed in the reactor. The system also includes a cyclone assembly. The cyclone assembly removes the bio-char from the synthesis gas.
