ResumoThis paper describes the steady-state simulation of a moving bed downdraft gasifier which allows the conversion of agricultural biomass into a hydrogen-rich gas mixture so that it has an adequate composition for being used as a feedstock in a molten carbonate fuel cell (MCFC). In order to emphasize the applicability of the results, fuel specifications for a 250 kW MCFC (HM-300, MTU, Friedrichshafen, Germany) was used as a reference. The final design makes possible to produce 350 Nm3/h of a biogas in a vessel of 0.8 m diameter × 2.5 m height capable of treating 50 kg/h of dry biomass using 45 Nm3/h of air at 800 K and 1 bar.
