Syngas production from microwave-assisted air gasification of biomass: Part 2 model validation
Experiments were conducted in this study (part 2) to validate the CFD model developed for microwave assisted air gasification of biomass (part 1). The experiments were conducted on corn stover at different gasification temperatures (600 degrees C, 700 degrees C, 800 degrees C). The simulated syngas components (H-2, CO, CO2, N-2, CH4 and C2H4) and heating values (high heating value (HHV) and low heating value (LHV)) were compared with the experimental results. The results show that most (94.44%) of the relative errors (7.84% - 19.34%) were within 20% for the syngas components, whereas they were 5.40%-8.62% and 3.29% -4.94% for the HHVs and LHVs, respectively, indicating that the model developed can be used to simulate syngas production from microwave-assisted air gasification of biomass.
