This dataset includes experimental raw data corresponding to the data shown in the linked manuscript, which is titled "Low-temperature on-board hydrogen production using a novel hollow fibre-based packed bed reactor". This comprises raw data for all light-off experiments and characterisation data. // The development of efficient on-board hydrogen generation technologies via ammonia decomposition necessitates dual advancements in catalyst and reactor design. However, significant challenges remain due to the absence of cost-effective, highly active catalysts and efficient reactors capable of satisfying the demands of on-board operation. Therefore, this work investigated cobalt molybdenum (CoMo)-based oxide and nitride catalytic systems to gain insight into the relationships among catalyst composition, stability and performance in ammonia decomposition, while a novel hollow fibre packed bed reactor (HFPBR) was introduced, for the first time, as a novel reactor concept. The significant performance variation of CoMo-oxide and nitride catalytic systems is demonstrated, extending over a T50 range of 120 °C. The nitride-based catalysts have emerged as promising catalyst candidates due to their superior activity and stability, exhibiting low-temperature activity above 380 °C. Moreover, various HPPBR configurations, each incorporating a CoMo-nitride catalyst, were investigated, with the optimal configuration demonstrating a 10-fold increase in the ammonia consumption rate at 425 °C, compared with the least effective configuration. These findings establish the HFPBR, coupled with a CoMo-based nitride catalyst, as a promising and efficient solution for on-board hydrogen production.
