The present embodiments provide additive systems for biomass gasification reactors. For example, in one embodiment, a biomass gasification system includes a feedstock preparation system configured to generate a biomass feedstock having a biomass fuel and a tar cracking additive. The system also includes a gasifier configured to receive the biomass feedstock and gasify the biomass fuel in the presence of the tar cracking additive to generate first and second mixtures. The first mixture has producer gas and the second mixture has the tar cracking additive and ash. The biomass gasification system further includes an additive recycle system configured to receive the second mixture and to separate at least a portion of the tar cracking additive from the ash to generate a recycled additive feed for the feedstock preparation system.

Additive systems for biomass gasification

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.

The disclosed embodiments provide systems for the removal and use of tar from a biomass gasification system. For example, in one embodiment, a biomass gasification system includes a reactor configured to gasify a biomass fuel in the presence of air to generate a producer gas. The system also includes an absorber configured to receive a mixture of the producer gas and tar and to absorb the tar into an organic solvent to produce treated producer gas and a rich solvent mixture containing at least a portion of the tar. The system further includes a recycle line configured to direct the rich solvent mixture to a biomass gasifier.

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.

Methods of activating charcoal resulting from biomass gasification

Biomass gasification systems including a biofilter assembly adapted to be disposed within a filter unit of a biomass gasification system are provided. The biofilter assemblies may be adapted to filter particulate matter from a producer gas flowing through the filter unit while allowing a remainder of the producer gas to pass through the biofilter assembly. The biofilter assembly may include a support structure and a biofilter disposed on the support structure and including a biomaterial adapted to be gasified in a biomass gasification reactor of the biomass gasification system.

Biofilter assemblies for biomass gasification systems

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.

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.
