Abstract
The various embodiments of the present invention relate generally to the process of gasification and the production of synthesis gas. More particularly, the various embodiments of the present disclosure relate to the process of biomass gasification and the reduction or elimination of tars from the hydrocarbon-rich product gas derived from biomass gasification. The present invention comprises systems and methods for the reduction of tar from a synthesis gas derived from biomass gasification.
Claims15
A biomass gasification system comprising:
- a combustor for heating a fluidized particulate material;
- a gasifier to heat a biomass feedstock with the heated fluidized particulate material, to produce a product gas comprising a tar;
- and
- a reactor to react an oxygen-containing gas with the product gas comprising a tar to at least partially oxidize the tar to produced an at least partially oxidized product gas.
1 more element
A biomass gasification method, comprising:
- heating a fluidized particulate material in a combustor;
- transferring the heated fluidized particulate material to a gasifier;
- introducing a biomass feedstock to the gasifier, wherein heat from the fluidized particulate material causes the gasification of at least a portion of the biomass feedstock to form a tar-containing product gas;
- and
- introducing the tar-containing product gas and an oxygen-containing gas into a reactor, wherein the oxygen-containing gas reacts with the tar to oxidize at least a portion of the tar of the tar-containing gas to produce an at least partially oxidized product gas comprising less tar than the tar-containing product gas.
