Effects of Ni particle size on amination of monoethanolamine over Ni-Re/SiO2 catalysts

H2 Production from Partial Oxidation of iso-Octane over Ni/Ce0.75Zr0.25O2 and Ni/β- Al2O3 Catalysts

In this study, the partial oxidation of iso-octane over Ni/Ce0.75Zr0.25O2 and Ni/β”Al2O3 catalysts was investigated. The results indicated that Ni/Ce0.75Zr0.25O2 is more active than Ni/β”-Al2O3. The partial oxidation products are mainly H2 and CO for Ni/Ce0.75Zr0.25O2 with hydrogen selectivity up to 85%. The H2/CO ratio is in the range of 1.3-2.0 depending on the operating temperature. It was n...

Effects of Impregnation Methods and Drying Conditions on Quinoline Hydrodenitrogenation over Ni-W Based Catalysts

Os efeitos dos métodos de impregnação (co-impregnação e impregnação sequencial) e das condições de secagem (ar e vácuo) sobre estrutura e o comportamento catalítico de catalisadores Ni-W suportados em MCM-41 foram investigados. Os catalisadores foram caracterizados por difratometria de raios X de pó (XRD), espectroscopia de absorção no infravermelho com transformada de Fourier (FT-IR), espectro...

Enhanced Oxygen Activation over Supported Bimetallic Au-Ni Catalysts

CO x Free Hydrogen Production by Catalytic Decomposition of Methane Over Porous Ni/Al2O3 Catalysts

Shape and size effects on layered Ni/PZT/Ni composites magnetoelectric performance

This paper presents the magnetoelectric (ME) effect in trilayered Ni/PZT/Ni composites which is related to their size and shape. The ME composites with the same interfacial areas but different geometrical shapes have different ME voltage coefficients. Longitudinal resonant modes in the rectangular and triangular trilayered ME composites were studied. One should choose optimized size, shape and ...
