Catalytic gasification of a residual biomass, obtained from yellow horn (YH) (Xanthoceras sorbifolia Bunge), an energy crop, was conducted to obtain a fuel gas rich in hydrogen. Unsupported nickel‐based catalyst modified with cerium was developed, characterized, and used in the advanced catalytic gasification of this residual biomass, using H₂O + CO₂ as the gasifying agent. Tests were performed in a thermobalance coupled to a mass spectrometer to identify the different steps involved in the gasification process and to correlate them with the estimated kinetic parameters. The sequential processes identified were: dehydration‐devolatilization, pyrolysis and gasification. The main pyrolysis step presented a calculated activation energy value of 102 kJ mol⁻¹. A positive effect was observed for the catalyst in the syngas obtained. A synergistic effect of CO₂ and H₂O used as gasifying agents was found in the gas yield. Hydrogen production was promoted by several reforming and cracking reactions, aided by CeO₂‐NiO catalyst able to co‐activate H₂O + CO₂. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd

与未负载的Ni-Ce催化剂相比，生物质催化气化性能可高产氢气

从能源作物黄角（YH）（Xanthoceras sorbifolia Bunge）获得的残留生物质进行催化气化，以获得富含氢气的燃料气体。使用H ₂ O + CO ₂作为气化剂，开发，表征了无负载的铈修饰的镍基催化剂，并将其用于该残留生物质的高级催化气化。在与质谱仪耦合的热天平中进行测试，以识别气化过程中涉及的不同步骤，并将它们与估计的动力学参数关联起来。确定的顺序过程是：脱水-脱挥发分，热解和气化。热解的主要步骤计算出的活化能为102 kJ mol^-1。对于所获得的合成气中的催化剂观察到了积极作用。在气体产率中发现了用作气化剂的CO ₂和H ₂ O的协同作用。通过能够重活化H ₂ O + CO ₂的CeO ₂ -NiO催化剂，通过几次重整和裂化反应促进了氢气的产生。©2019年化学工业协会和John Wiley＆Sons，Ltd
