Prediction of hydrogen production of a downdraft gasifier using equilibrium modeling for different moisture content for solid oxide fuel cell action (sofc).

Resumo

Equilibrium modeling has been used to predict the hydrogen production in a downdraft gasifier. The composition of syngas (synthesis gas), the lower heat value (LHV), hence, the cold efficiency of gasifier (?cg) have been determined. The effects of moisture content (MC) have been investigated for temperature of gasification 800 °C. The predicted values compare reasonably well with experimental data available in literature. The amount of hydrogen and CH4 increase with increase in the range of moisture content in the biomass (eucalyptus) investigated. The LHV and cold efficiency of gasifier decreases with increase in the range of moisture content.
