Effect of Adding Gadolinium Oxide Promoter on Nickel Catalyst over Yttrium-Zirconium Oxide Support for Dry Reforming of Methane.

The dry reforming of methane (DRM) was studied for seven hours at 800 °C and 42 L/(g·h) gas hourly space velocity over Ni-based catalysts, promoted with various amounts of gadolinium oxide (x = 0.0, 1.0, 2.

Modification of CeNiZrO Perovskite Catalyst by Partially Substituting Yttrium with Zirconia in Dry Reforming of Methane.

Methane Dry Reforming is one of the means of producing syngas. CeNi0.9Zr0.

Promotional effect of magnesium oxide for a stable nickel-based catalyst in dry reforming of methane.

The generation of synthesis gas (hydrogen and carbon monoxide mixture) from two global warming gases of carbon dioxide and methane via dry reforming is environmentally crucial and for the chemical industry as well. Herein, magnesium-promoted NiO supported on mesoporous zirconia, 5Ni/xMg-ZrO (x = 0, 3, 5, 7 wt%) were prepared by wet impregnation method and then were tested for syngas production via dry reforming of methane. The reaction temperature at 800 °C was found more catalytically active than that at 700 °C due to the endothermic feature of reaction which promotes efficient CH catalytic decomposition over Ni and Ni-Zr interface as confirmed by CH-TSPR experiment.
