چکیده

Abstract Ni-Mg–Al ternary hydrotalcites (HTs) with molar ratio M 2+ (Ni + Mg 2 )/Al = 3, and different content of Ni, Ni0Mg3, Ni2Mg1, Ni3Mg0 were prepared. The HTs calcined then reduced to generate catalysts based on metallic which, used produce green diesel from a mixture stearic palmitic acids at 320 °C 1400 psia H . A reaction scheme was proposed; the main products alkanes n-C17 n-C15. prepared carry out, mainly, reactions decarboxylation (DCX) decarbonylation (DCN), some hydrocracking. most active catalyst Ni2Mg1 because it forms small clusters nickel, apparently stabilized MgO or NiO-MgO spinel like structures.

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...

Hydrogen Production from Biomass Gasification with Ni-Fe/Al Catalysts

Producing clean hydrogen from renewable resources will reduce our dependence on using fossil fuels towards a green and sustainable future. Biomass gasification is regarded as a promising technology for hydrogen production. In this work, low cost Ni-based catalyst was applied in a two-stage fixed bed reaction system. Fe was added into Ni-Al catalyst(80mol.% Al) by co-precipitation method with va...

Hydrogenation of ethyl acetate to ethanol over Ni-based catalysts obtained from Ni/Al hydrotalcite-like compounds.

A series of Ni-based catalysts were prepared using hydrogen reduction of Ni/Al hydrotalcite-like compounds (Ni/Al HTlcs) synthesized by coprecipitation. The physico-chemical properties of Ni/Al hydrotalcite-like compounds and the corresponding Ni-based catalysts were characterized using inductively coupled plasma (ICP), BET surface areas, X-ray diffraction (XRD), Fourier transform infrared (FTI...

Hydroprocessing of Jatropha Oil for Production of Green Diesel over Non-sulfided Ni-PTA/Al2O3 Catalyst

The non-sulfided Ni-PTA/Al2O3 catalyst was developed to produce green diesel from the hydroprocessing of Jatropha oil. The Ni-PTA/Al2O3 catalyst was prepared by one-pot synthesis of Ni/Al2O3 with the co-precipitation method and then impregnanting Ni/Al2O3 with PTA solution. The catalysts were characterized with BET, SEM-EDX, TEM, XRD, XPS, TGA and NH3-TPD. The Ni and W species of the Ni-PTA/Al2...

PRODUCTION OF HYDROGEN EMPLOYING Ni-Rh CATALYSTS IN MEMBRANE REACTORS

−− Rh, Ni and Rh-Ni catalysts were prepared by wet impregnation of La2O3. The Rh content was modified but the Ni loading was kept constant at 2 wt%. The solids were calcined at 823 K in air flow and were reduced at 973 K in flowing hydrogen. The activity, stability, and residue formation during the CO2 reforming of CH4, of all the catalysts were tested in a fixed-bed reactor. Those with low car...
