    Low-Temperature Methane Combustion Using Ozone over Coβ Catalyst by Shunsaku Yasumura (8519667)

    Published 2024
    “…The resulting path toward CO<sub>2</sub> formation shows an activation energy of 73 kJ/mol for the rate-determining step and an exothermicity of 1025 kJ/mol, which supports the experimental results. During a long-term catalytic test for 160 h without external heating, the CH<sub>4</sub> conversion gradually decreases from 80 to 40%, but the conversion fully recovers after dehydration at 500 °C (0.5 h). …”
