In the present work, biomass pyrolysis tar cracking and reforming for high quality syngas production using a rice husk char (RHC)-supported nickel catalyst (Ni/RHC) coupled with microwave heating was investigated. The Ni/RHC catalyst exhibited a high catalytic performance on tar removal and contributed well to the production of CO and H. The conversion efficiency could reach up to 97.3%, and the CO and H yields were 274.0 ml g and 248.9 ml g, respectively, at 700 °C, under microwave conditions, when the nickel loading amount was 10.42 wt% of the support. The tar conversion efficiencies and syngas yields significantly increased as the cracking temperatures increased from 500 °C to 700 °C and the nickel loading amount increased from 0 to 10.42 wt%. The Ni/RHC catalysts became more effective for tar removal and the production of syngas increased under microwave conditions compared to the results obtained under conventional conditions.
在本研究中，对利用稻壳炭（RHC）负载镍催化剂（Ni/RHC）耦合微波加热进行生物质热解焦油裂解及重整以生产高品质合成气展开了研究。Ni/RHC催化剂在焦油去除方面展现出高催化性能，并对CO和H的生成有良好促进作用。在微波条件下，当镍负载量为载体的10.42 wt%时，于700℃下转化率可达97.3%，CO和H产率分别为274.0 ml/g和248.9 ml/g。随着裂解温度从500℃升至700℃以及镍负载量从0增加到10.42 wt%，焦油转化率和合成气产率显著提高。与常规条件下的结果相比，Ni/RHC催化剂在微波条件下对焦油去除更有效，合成气产量增加。
