To address this, we've explored non-catalytic autothermal reforming in our preliminary experiments and observed enhanced reformer efficiency when using premixed fuel-oxidizer mixture. However, there was limitations to the extent of mixing achievable in the present pre-mixer design due to the occurrence of auto-ignition. This study aims to address these challenges by employing a detailed kinetic mechanism to examine how various operating factors such as reformer pressure and initial mixture temperature, impact ignition delay. Additionally, we've investigated the effects of recirculating a portion of reformate gas on reformer efficiency. Results indicate that tuning the pre-mixer ignition delay can significantly enhance mixing while avoiding auto-ignition, thereby increasing reformer efficiency. We expect these findings to inform the next generation of reformer design.falseAuto-ignition | Negative temperature coefficient | Non-catalytic reforming | Pre-mixer | Recirculation ratioArticle89-9631 March 20251arJournal1WOS:001441566900001
