• W3048163610 abstract "The present work investigated the production of Green Diesel through the deoxygenation of palm oil over Ni catalysts supported on γ-Αl 2 O 3 , ZrO 2 and SiO 2 for a continuous flow fixed bed reactor. A comprehensive experimental study was carried out in order to examine the effects of temperature, pressure, LHSV and H 2 /oil feed ratio on catalytic activity during short (6 h) and long (20 h) time-on-stream experiments. The catalysts were prepared through the wet impregnation method (8 wt% Ni) and were extensively characterized by N 2 adsorption/desorption, XRD, NH 3 -TPD, CO 2 -TPD, H 2 -TPD, H 2 -TPR, XPS, TEM/HR-TEM and Raman. The characterization of the materials prior to reaction revealed that although relatively small Ni nanoparticles were achieved for all catalysts (4.3 ± 1.6 nm, 6.1 ± 1.8 nm and 6.0 ± 1.8 nm for the Ni/Al 2 O 3 , Ni/ZrO 2 and Ni/SiO 2 catalysts, respectively), NiO was better dispersed on the Ni/ZrO 2 catalyst, while the opposite was true for the Ni/SiO 2 sample. In the case of Ni/Al 2 O 3 , part of Ni could not participate in the reaction due to its entrapment in the NiAl 2 O 4 spinel phase. Regarding performance, although an increase in H 2 pressure led to increases in paraffin conversion, the increase of temperature was beneficial only up to a critical value which differed for each catalytic system under consideration (375 °C, 300 °C and 350 °C for the Ni/Al 2 O 3 , Ni/ZrO 2 and Ni/SiO 2 catalysts, respectively). All catalysts favored the deCO 2 and deCO deoxygenation paths much more extensively than HDO, irrespective of testing conditions. Time-on-stream experiments showed that all catalysts deactivated after about 6 h, which was attributed to the sintering of the Ni particles and/or their covering by a thin graphitic carbon shell. • An increase of temperature benefits the overall reaction only up to a critical value. • The optimum reaction temperature differs between catalytic systems. • The catalysts tested herein promote mainly the deCO 2 and deCO deoxygenation paths. • All catalysts suffered varying degrees of sintering during reaction. • The carbon formed on to the spent catalyst surface was a very thin graphitic shell." @default.
