Microwave-assisted heating is an effective heating method for thermochemical conversion of biomass. In this study, experimental syngas production from microwave-assisted air gasification of biomass in a fluidized bed reactor at different gasification temperatures, equivalence ratios and silicon carbide loads, was studied and reported. The results showed that the highest syngas yield (78.2 wt%), higher heating value (6.3 MJ/Nm³) and cold gas efficiency (81.8 %) were obtained at gasification temperature of 900 °C, equivalence ratio of 0.35 and silicon carbide load of 30 g, and the gasification temperature had significant influence on the syngas production. Microwave-assisted heating showed positive effect on tar reduction, i.e., the tar content at 900 °C (2.1 wt%) in this study was even lower than the tar content (3.2 wt%) from catalytic electrical air gasification of rice husk at 950 °C. Generally, the introduction of microwave-assisted heating showed positive effect on biomass gasification.

微波辅助加热是一种有效的生物质热化学转化加热方法。在这项研究中，研究并报告了在不同气化温度、当量比和碳化硅负载下，在流化床反应器中通过微波辅助空气气化生物质生产合成气的实验性合成气。结果表明，合成气收率最高（78.2 wt%），热值较高（6.3 MJ/Nm ³)和冷气效率(81.8%)在气化温度900℃、当量比0.35和碳化硅负载30g时获得，气化温度对合成气产量有显着影响。微波辅助加热对减少焦油有积极作用，即本研究中 900 °C 的焦油含量（2.1 wt%）甚至低于 950 ℃时稻壳催化电空气气化的焦油含量（3.2 wt%）摄氏度。一般来说，微波辅助加热的引入对生物质气化有积极的影响。
