A dual bed pyrolysis system may include a falling bed reactor employing a heat carrier particulate to pyrolyze biomass to create a pyrolysis product and a pyrolysis waste product. The dual bed pyrolysis system may also include a fluidized bed reactor. The fluidized bed reactor may accept the pyrolysis waste product including char and heat carrier particulate from the falling bed reactor. The fluidized bed reactor may combust the char in the presence of the heat carrier particulate. The fluidized bed reactor may combust the char to reheat the heat carrier particulate. The reheated heat carrier particulate may be provided to the falling bed reactor to pyrolyze biomass to create a pyrolysis product and a pyrolysis waste product.
