| 摘 要： | 微动力装置中碳氢燃料催化燃烧被认为是有效的方法,但燃烧室内燃料催化重整普遍存在由积碳导致的催化剂失活等问题.本文采用数值方法研究了微细腔中甲烷湿空气在镍基催化剂上的自热重整反应,重点分析含湿量对甲烷自热重整反应及积碳特性的影响.结果表明:含湿量将增强甲烷重整反应;自热反应散热量和表面积碳浓度均随含湿量增加而降低.混合物...

| Abstract: | Catalytic combustion of hydrocarbon fuels has been considered as an effective method in power MEMS.However,the catalyst deactivation,mainly caused by carbon deposition,is occurred ubiquity in the catalytic reforming progress.In this paper,the effects of humidity ratio on the CH_4/wet air auto-thermal reforming reaction with Ni catalyst on the micro-chamber's surface were simulated.The results show that increasing the humidity ratio will promote the methane reforming reaction.The heat dissipating capacity of... |
