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

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.
