Abstract: | The purpose of this study was to establish a fuel process for an advanced power generation system in which hydrogen-rich synthesis
gas, as the fuel for the molten carbonate fuel cell (MCFC), can be extracted from biomass via gasification and reforming technologies.
Experiments on waste wood gasification were performed using a bench-scale gasification system. The main factors influencing
hydrogen generation in the noncatalytic process and in the catalytic process were investigated, and temperature was identified
as the most important factor. At 950°C, without employing a catalyst, hydrogen-rich synthesis gas containing about 54 vol%
hydrogen was extracted from feedstock with appropriately designed operation parameters for the steam/carbon ratio and the
equivalence ratio. However, by employing a commercial steam reforming catalyst in the reforming process, similar results were
obtained at 750°C. |
