| Abstract | One of the major issues in the biomass gasification technology is how to deal with the biomass tar. Tar is an undesirable product of biomass gasification because of the various problems associated with the condensation and formation of tar aerosols, which presents significant impediment to the application of biomass gasification systems. Catalytic and noncatalytic tar steam reforming were studied in this research by using naphthalene as a model tar compound. The experiments were conducted in a lab-scale fixed bed reactor operated at 800?C. Catalytic performance on naphthalene decomposition was compared among experiment without catalyst, with 12%Fe/Al2O3, 3%Ni-12%Fe/Al2O3 and 12%Ni3%Fe/Al2O3 catalysts. The results showed that low amount of Ni added, i.e. the case of 3%Ni-12%Fe/Al2O3 catalyst, gave the higher catalytic performance in tar steam reforming when compared with the case of 12%Fe/Al2O3 catalyst and with 12%Ni-3%Fe/Al2O3 catalyst. The carbon conversion into gas was increased to around 27% with the highest production of H2 and CO (i.e. around 37 and 15 mmol/g feed, respectively) among all the cases. This was probably due to the presence of Ni-Fe bimetallic particles on the catalyst. |
