Nickel-Promoted Molybdenum or Tungsten Carbides as Catalysts in Dry Reforming of Methane: Effects of Variation in CH4/CO2 Molar Ratio

Ni-Mo2C and Ni-WC were evaluated in dry reforming of methane employing different CH4/CO2 ratios. Ni-Mo2C remained active under an excess of CH4, but deactivation occurred under an excess of CO2. Ni-WC was resistant to excess of CO2 but showed carbon deposition under excess of CH4. [GRAPHICS] .

Automated summary

Ni-Mo2C remains active with excess CH4 but deactivates with excess CO2, while Ni-WC is resistant to excess CO2 but shows carbon deposition with excess CH4.
