Abstract

In this paper, OpenFOAM was employed to numerically investigate syngas (H₂ and CO) production by the simultaneous splitting of H₂O and CO₂ via thermochemical redox cycle based on iron oxide (Fe₃O₄). The effects of operating conditions such as pressure, temperature and species reactant ratios on syngas yield were investigated. The results indicated that amount of syngas yield was highly dependent on the reduction temperature. It was found that the process at high pressure could lower the reaction temperature and increased species production rate. The overall syngas yield increased from 1.34% up to 98.65% when the pressure increased from 5 to 20 atm. The analysis of the results showed that the syngas yield and the syngas composition were strongly influenced by the ratio of H₂O/CO₂ (γ_g). The highest syngas purity (ratio of H₂/CO (γ_s)) = 3.36 was reached at γ_g = 2. The optimum operating conditions for hydrogen-rich syngas production were obtained when γ_g = 2 under 1600 K at 20 atm.
