    Thermodynamic analysis of solar-driven chemical looping steam methane reforming over Cr2O3/Cr redox pair by Bhosale, Rahul

    Published 2019
    “…The total solar energy required to drive the CS process (Q-solar-CS) rises by 1498.8 kW as the CH4/Cr2O3 molar ratio upsurges from 0.5 to 3. In case of the CSH process, when the TL increases from 500 to 1400 K, the Q solar CSH decreases by 54.5 kW and further surge in the TL from 1400 to 2050 K yields into upturn in the Q-solar-CSH by 108.5 kW. …”
