Staged gasifiers, where pyrolysis and gasification occur separately instead of in the same reaction zone as was the case in the World War II gasifiers, can be engineered to produce essentially tar-free gas (less than 1 mg/m 3), while single-reactor fluidized bed gasifiers may exceed 50,000 mg/m³ tar. The fluidized bed reactors have the ...
