Methane dry reforming on Ni/Ce0.75Zr0.25O2–MgAl2O4 and Ni/Ce0.75Zr0.25O2–γ-alumina: Effects of support composition and water addition

Effect of support composition on the origin and reactivity of carbon formed during dry reforming of methane over 5wt% Ni/Ce1−xMxO2−δ (M=Zr4+, Pr3+) catalysts

“…This is in general agreement with literature reports for other CeO 2 -basedand Ce 1−x Zr x O 2 -supported Ni for feed gas compositions similar to or different than that used in this work [2,[10][11][12][13][14][15][16][17][18][19]. In the case of Ni/Ce 0.8 Pr 0.2 O 2−ı catalyst, values slightly higher than unity for the H 2 /CO ratio were obtained ( Table 3).…”

“…Ceria-based and in particular ceria-zirconia solid solutions have been reported to exhibit significant improvements in "carbon" formation reduction and catalyst's stability compared to other non-reducible metal oxide supports (e.g. ␥-Al 2 O 3 , SiO 2 ) [2,[10][11][12][13][14][15][16][17][18][19][20][21].…”

Dry Reforming of Methane Over Various Doping Level of Ce on La1-Xcexni0.4Fe0.6o3perovskitenanocatalyst

“…Synthesis gas can be applied in the Fischer-Tropsch synthesis industry to produce valuable chemicals 3,4 . The low H 2 /CO ratio is preferentially used for further applications such as methanol and liquid fuel synthesis 5,6 . In recent years complex mixed metal oxides with the perovskite-type structure have been studied in catalysis and have been proposed for methane-reforming reactions in replacement of classical catalysts such as noble metal-based catalysts 7,8 .…”

Dry reforming of methane over nanostructured Co/Y catalyst for hydrogen production: Effect of ultrasound irradiation and Co-loading on catalyst properties and performance

“…Therefore, the synthesis method can improve the catalytic performance [2,4,10,11]. In recent researches, due to the drawbacks of conventional methods like impregnation, precipitation, sol-gel, and hydrothermal [12][13][14], the great attentions have been paid to utilize the modern methods such as sonochemical, plasma and microwave [1,2,4,11,15].…”

“…Apart from preparation method, the active phase and the support are the other key factors affecting the physicochemical properties of catalysts [2,10,23,41,42]. In order to resolve catalysts drawbacks in DRM process, many supports were evaluated in dry reforming of methane at the past studies.…”
