- Abstract
- The pyrolysis and gasification is energy conversion technology for biomass to produce synthetic gases for industrial use. The tar in the thermal decomposition gas from the pyrolysis or gasification process, however, damages synthetic gas facilities and causes operation trouble. A gliding arc plasma reformer for tar decomposition was developed to address the aforementioned problem. The performance in decomposition mechanism and characteristic was conducted for a pyrene as a surrogate of biomass tar. Parametric experiments were conducted for steam feed rate, input power, total gas amount, and input tar concentration. Through experimental results, decomposition efficiency, energy efficiency, reforming gas and carbon black concentration have been established. At optimal conditions, decomposition efficiency was 88.3%, while energy efficiency of 0.13 g/kWh was obtained. The higher heating value of the producer gas was 11,308 kJ/Nm3 (excluding N2) with carbon balance of 93.8%.
