Green diesel production from renewable non-edible feedstock through deoxygenation (DO) is a viable step to reduce dependency on petroleum-based fuel in the transportation sector. As such, the catalytic conversion of undiluted palm fatty acid distillate (PFAD) into paraffinic hydrocarbons through DO was explored using Nidoped pyrolysed MIL-101 (MOF-Cr2O3). In this study, 4-25 wt% Ni/MOF-Cr2O3 catalysts were prepared through wet impregnation and calcined at 600 degrees C for 4 h under N2 flow, followed by reduction at 450 degrees C for 4 h under H2 flow. Catalytic DO was carried out within 280 degrees C-360 degrees C with a retention time of 1-5 h by using 1-7 wt.% of catalyst loading under continuous N2 flow. Results showed that 14Ni/MOF-Cr2O3 was the most effective catalyst for PFAD conversion into paraffinic hydrocarbons. About 93 % hydrocarbon yield with 91 % n- (C15+C17) selectivity was achieved using 3 wt% catalyst at 320 degrees C within 3 h. The exceptional catalytic activity was attributed to the synergistic correlation between catalyst properties, including finely dispersed Ni facilitated by a porous and high surface area support, and optimal presence of acid-base active sites on the catalyst. Preliminary studies showed that 14Ni/MOF-Cr2O3 displayed high stability in terms of catalytic activity and regeneration potential.
