Syngas production from microwave-assisted air gasification of biomass: Part 2 model validation

Abstract 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 °C, 700 °C, 800 °C). The simulated syngas components (H 2 , CO, CO 2 , N 2 , CH 4 and C 2 H 4 ) 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.
