Continuous selective deoxygenation of palm oil for renewable diesel production over Ni catalysts supported on AlO and LaO-AlO.

The present study provides, for the first time in the literature, a comparative assessment of the catalytic performance of Ni catalysts supported on γ-AlO and γ-AlO modified with LaO, in a continuous flow trickle bed reactor, for the selective deoxygenation of palm oil. The catalysts were prepared the wet impregnation method and were characterized, after calcination and/or reduction, by N adsorption/desorption, XRD, NH-TPD, CO-TPD, H-TPR, H-TPD, XPS and TEM, and after the time-on-stream tests, by TGA, TPO, Raman and TEM. Catalytic experiments were performed between 300-400 °C, at a constant pressure (30 bar) and different LHSV (1.
