Moreover, the catalytic performances were evaluated in a fixed bed tubular reactor, and the experimental results indicated Ni/Al 2O 3–Y 2O 3–3%Nd 2O 3 demonstrated an outstanding activity and stability at 800 ☌ owing to both inhibition of carbon deposition and Ni agglomeration, which was largely due to the sufficient oxygen vacancies. The XRD, BET, TEM, TG, CO 2-TPD and XPS were used to characterize the morphology and physicochemical properties of the prepared samples, confirming the Nd 2O 3 addition in Ni/Al 2O 3–Y 2O 3 catalysts behaved abundant oxygen vacancies, increased basicity of the support, mesoporous structures with small metallic Ni particle size, and high dispersion of Ni.
Nd 2O 3 promoted Ni-based catalysts have ample oxygen vacancies, which could promote the decomposition of carbon dioxide into CO and O* species and thus may perform a favorable anti-coking ability to overcome this difficulty, and Ni/Al 2O 3–Y 2O 3–x%Nd 2O 3 (x = 0, 2, 2.5, 3, 3.5, 4) catalysts were synthesized by sol–gel method and employed in DRM.
