Abstract: The present application thus provides a gasifier for use in converting a feedstock material into a syngas. The gasifier may include an outer chamber, a reaction zone positioned within the outer chamber, and a disruption device maneuverable within the outer chamber to ensure a steady flow of the feedstock material into the reaction zone without bridging.

Abstract: Methods for activating charcoal resulting from biomass gasification are provided. Exemplary methods include gasifying biomass in a gasification reactor of an integrated biomass gasification system to produce charcoal; and activating charcoal using heat generated from an integral heat source of the integrated biomass gasification system. The methods include activation of charcoal resulting from biomass gasification in a more efficient, economical manner, thereby increasing the value of biomass gasification with minimal investment in the process.

Abstract: A system includes a gasifier configured to gasify a mixture of a biomass feedstock and an oxidant to generate a producer gas and a producer gas purification system configured to purify the producer gas from the gasifier. The system also includes a gas supply system configured to supply a gas that is not the oxidant to at least one of the gasifier, or the producer gas purification system, or any combination thereof.

Abstract: Systems for recovering heat from a biomass gasifier are provided. One gasification system includes a gasifier having an inlet section configured to receive a biomass feedstock and air, and a reactor section configured to gasify a mixture of the biomass feedstock and the air to generate a producer gas. The gasifier also has an outlet section configured to output the producer gas from the reactor section. The gasification system also includes a heat exchanger system coupled to the gasifier. The heat exchanger system is configured to recover heat from the gasifier by transferring heat to a fluid to create a heated fluid.

Abstract: In an embodiment, a system includes a methanation section generally including a fuel inlet configured to receive a first fuel, a fuel outlet configured to output methane, and a first fuel path configured to route a first flow of the first fuel from the fuel inlet to the fuel outlet. The first fuel path includes a first methanator configured to generate the methane from the first fuel in an exothermic methanation region. The system also includes a second fuel path configured to route a second flow of a second fuel without conversion to methane. The second fuel path is also configured to receive heat from the exothermic methanation region.
