Abstract: Methods and systems for producing hydrogen from methane or other fuels that has lower input heat requirements than conventional steam reformation schemes are provided. The system has a reactor with a controlled feed of fuel, water/steam, CO and recycle gases. The methods generally use significantly high amounts of steam (water) and carbon monoxide (CO) in the feed that substantially enhances the reaction rate of the water-gas shift reaction, which transforms CO and H2O to CO2 and H2. Since this reaction is exothermic, its enhancement alters the endothermic nature of the overall reforming process to the point where the overall reforming process is no longer endothermic. The CO requirements may be met in part with the reverse water-gas shift reaction from CO2 produced by the reactor. The lower heat requirements may be satisfied with renewable sources such as solar or from hydrogen produced by the system.

Abstract translation: 提供了用于从具有比常规蒸汽重整方案更低的输入热需求的甲烷或其他燃料生产氢气的方法和系统。 该系统具有燃料，水/蒸汽，CO和再循环气体受控进料的反应器。 这些方法通常在进料中使用显着大量的蒸汽（水）和一氧化碳（CO），这大大增强了水煤气变换反应的反应速率，其将CO和H 2 O转化为CO 2和H 2。 由于该反应是放热的，因此其增强改变了总体重整过程的吸热性能，直到整个重整过程不再吸热。 CO要求可能部分地由反应器产生的CO 2的反向水煤气变换反应来满足。 较低的热量要求可以满足可再生能源，例如太阳能或由系统产生的氢。
