Biomass gasification for hydrogen production was performed in a continuous-feeding
fluidized-bed with the use of Fe/CaO catalysts. The relationship between catalyst properties
and biomass gasification efficiencies was studied. The findings indicated that only CaO
was involved in the enhancement of char gasification, resulting in an increased hydrogen
production. However, CaO was also easily deactivated by biomass tar. The characterization
results indicated that when CaO was impregnated with Fe, Ca2Fe2O5 formed on the surface
of the support. Ca2Fe2O5 decomposed polyaromatic tar but was not effective in char gasification.
The synergistic effects between Fe and CaO that effectively enhanced biomass
gasification mainly involved combustion and pyrolysis, and the biomass gasification
products, i.e., char and tar, were further gasified, indicating that tailor-made Fe/CaO
catalysts prevented CaO deactivation by tar, thus promoting biomass gasification and
hydrogen production.
