“…Syngas with an H 2 /CO ratio larger than one can be produced via steam reforming of methane (SRM) or direct combustion. [14,15] or the technique of partial oxidation of methane (POM) [3]. While the POM process exhibits di culties related to capital cost and safety concerns due to pure oxygen in a high-pressure system [16], the SRM process copes with issues related to equipment corrosion due to a high inlet water amount [14].…”

This research involved performing steam-assisted dry reformation (SDR) on methane over a CoMo2/Al2O3 nanoflake catalyst irradiated at microwave frequencies. CoMo2 nanoflakes showed great catalytic activity for reforming reactions due to their excellent exposed surface to the incident MW and better ability to absorb MW. Fischer-Tropsch (F-T) synthesis is used to manufacture liquid fuels, and the predicted syngas ratio (H2/CO) can be easily modified by adjusting the quantity of steam to carbon ratio (S/C) supplied into the reactor. With an intake S/C ratio of less than (0.1) and (200 W) of MW power, it is possible to get an H2/CO ratio greater than one. Compared to carbon-based catalysts, the catalytic stability of the CoMo2 nanoflakes catalysts was much higher after 16 hours of time-on-stream (TOS) of the SDR process while being exposed to MW irradiation. Steam combination dry reforming, MW assistance, and a CoMo catalyst are some keywords that might be used here.
