“…The highest CO selectivity of 20.95% at unity feed ratio and temperature of 1023 K was observed for the Co/CeO2 catalyst. This trend could be as a result of increase in adsorption of CO2 on the CeO2 site which gives corresponding CO. Shi et al [34] reported similar trend in their study on methane dry reforming over Ni/Mo2C catalyst. The authors' findings show that CO2 activation took place on Mo2C support site producing CO and O radical.…”

Production of CO-rich hydrogen gas from methane dry reforming was investigated over CeO2-supported Co catalyst. The catalyst was synthesized by wet impregnation and subsequently characterized by field emission scanning electron microscope (FESEM), energy-dispersive X-ray spectroscopy (EDX), liquid N2 adsorption-desorption, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) for the structure, surface and thermal properties. The catalytic activity test of the Co/CeO2 was investigated between 923-1023 K under reaction conditions in a stainless steel fixed bed reactor. The composition of the products (CO and H2) from the methane dry reforming reaction was measured by gas chromatography (GC) coupled with thermal conductivity detector (TCD). The effects of feed ratios and reaction temperatures were investigated on the catalytic activity toward product selectivity, yield, and syngas ratio. Significantly, the selectivity and yield of both H2 and CO increases with feed ratio and temperature. However, the catalyst shows higher activity towards CO selectivity. The highest H2 and CO selectivity of 19.56% and 20.95% respectively were obtained at 1023 K while the highest yield of 41.98% and 38.05% were recorded for H2 and CO under the same condition.

“…Indeed, the activity of molybdenum and tungsten carbides (Mo 2 C and WC) in dry reforming of methane, partial oxidation and stream reforming of methane to synthesis gas was found to be higher than Pt and Pd-based catalysts, though still lower than the activity measured for Ru and Rh catalysts [12]. Shi et al reported high catalytic activity and stability for a Ni-Mo 2 C catalyst in dry reforming of methane [13]. The activity of Mo 2 C and WC was linked to their facility to activate the extremely stable CO 2 molecule.…”

CO 2 methanation with Hydrogen to form CH 4 offers a solution for off-peak renewable energy storage. γ-alumina-supported Mo and Ni-Mo catalysts were used in CO 2 methanation, either in their reduced or in their carburized form. The presence of Ni improved the carburization extent of Mo-species, resulting in increased catalytic activity and selectivity for the catalytic CO 2 methanation reaction. Carburization generally enhances the basicity of the materials and thus CO 2 absorption on their surface. At 300˚C, the conversions of CO 2 for the reduced Ni-Mo/Al 2 O 3 catalyst and Ni-Mo 2 C/Al 2 O 3 catalysts were 5.3% and 13.8% respectively with a corresponding selectivity in CH 4 of 10.0% and 98.1%, respectively.
