Hydrogen stands as a pivotal energy carrier with significant potential to facilitate the global transition towards a low-carbon energy future. The main challenge in current stage is the production of hydrogen with less emission and high efficiency. To resolve this problem, chemical looping hydrogen production (CLHP) is proposed and investigated. The key factors influencing the efficiency of CLHP are the gas-solid flow, heat transfer and mass transfer processes. A dual-reactor system is established in this work and numerical model based on CPFD is utilised for investigating the reaction characteristics. Hydrogen production decreases with increasing gas velocity in the hydrogen production reactor. Variations in the solid circulation rate alter the mass and heat distribution within the system, consequently affecting the hydrogen production rate. A riser gas velocity of 7 m/s and a circulation rate of 0.15 kg/s are the recommended values for the current constructor. Overall, reactor temperature remains the predominant influencing factor. This study provides insights for reactor optimization and scale-up design.
