Selective Deoxygenation of Waste Cooking Oil to Diesel-Like Hydrocarbons Using Supported and Unsupported NiMoS₂ Catalysts.

For the unsupported and γ-Al 2 O 3 -supported NiMoS 2 catalysts with Ni/(Ni + Mo) atom ratios of 0.2 compared with 0.3, the 0.2-NiMoS 2 catalyst increased the HDO rate of oleic, palmitic, and linoleic acids, whereas at a higher Ni/(Ni + Mo) ratio of 0.3, there was a clear trend of decreasing the n -C 14 –C 18 yield (about 8 and 7% for the WPO and WSBO, respectively) and selectivity.
