The reaction is an autothermal reaction [20] and it can be
triggered at millisecond contact time to generate syngas with high
selectivity [21]. The reaction mechanisms of CPOM involve
methane combustion, steam reforming, and dry (or carbon
dioxide) reforming [22]. From the thermodynamic point of view,
dry reforming will be intensified if carbon dioxide is added into the
influent, thereby enhancing hydrogen and syngas yields from
methane. Besides, CO2 emissions from industry can be mitigated if
it is reused in CPOM. Inspired from Le Chatelier’s principle, carbon
dioxide generated from anthropogenic activities can become the
feedstock for hydrogen and syngas production.
In reviewing past literature, a number of studies have been
performed on dry reforming via reusing carbon dioxide for
