Abstract
The gasification of a carbonaceous material includes receiving a volume of feedstock, supplying thermal energy to the volume of feedstock to convert at least a portion of the volume of feedstock to at least one pyrolysis reaction product via at least one pyrolysis reaction, super-heating the at least one pyrolysis reaction product, providing a volume of super-heated steam, mixing the volume of super-heated steam with the super-heated at least one pyrolysis reaction product and converting at least a portion of at least one reformed product to at least one synthesis gas product via at least one water-gas-shift reaction.
