【 摘 要 】

Producer gas from biomass gasification is tormented by the demeanour of tar which causes pipe blockages, plugging, corrosion, and catalyst deactivation. Thermo-catalytic tar models decomposition via microwave irradiation has been shown to be effective method in reducing tar from producer gas. This study, toluene and naphthalene were used as tar models with N2 as the carrier gas followed by the use of spurious producer gas. Thermal and catalytic decomposition of tar models with over a wide temperature range from 850 °C to 1,200 °C and 650 °C to 900 °C, respectively, at residence time of 0.24-0.5 s. In term of catalytic treatment, Ni/Mg/Al2O3 which the improved catalyst was used to remove both of tar models too. The results showed that the high tar removal efficiency both of thermal and catalytic cracking method. In addition, toluene was much easier to be reduced than naphthalene.
