在填充床反应器中，利用空气和空气-水蒸气混合物进行了生物质颗粒的自热上升式气化。空气-水蒸气气化产生的合成气的热值比空气气化产生的4.4MJ/mN3略有提高，热值为4.5MJ/mN3。空气气化焦油生成量为21.2g/mN3，空气-水蒸气气化焦油生成量为26.2g/mN3。空气气化和空气-水蒸气气化的冷气效率分别达到91%和91.4%。空气-水蒸气气化的碳转化率约为91.5%，而空气气化的碳转化率仅为84.3%。
Auto-thermal updraft gasification of biomass pellets in a packed bed reactor was conducted by using air and air–steam mixture. Air–steam gasification produced syngas with slightly improved lower heating value of 4.5 MJ/mN3in comparison to 4.4 MJ/mN3produced during air gasification. The corresponding tar generation for air gasification and air–steam gasification was 21.2 g/mN3and 26.2 g/mN3, respectively. Cold gas efficiency for air gasification and air–steam gasification was realized to be 91% and 91.4%, respectively. Carbon conversion during air–steam gasification reached about 91.5% while carbon conversion during air gasification was limited to 84.3%.
