Auto-thermal reforming of biomass raw fuel gas to syngas in a novel reformer: Promotion of hot-electron
Wang, Tiejun; Yang, Yong; Ding, Mingyue; Liu, Qiying; … - In: Applied Energy 112 (2013) C, pp. 448-453
A novel reformer with porous ceramic oxygen distribution tube circled by electric wire for inspiring hot electron was designed for auto-thermal reforming of biomass raw fuel gas to produce syngas (H2+CO). The temperature of auto-thermal reformer was nearly uniform due to the excellent...
