    The basic and amphoteric oxides MgO and Al2O3, ZrO2 do not lead to highly active NiMo catalysts presumably due to low hydrothermal stability during HDO. The most active catalysts represented NiMo sulfides supported on TiO2 and C, which yielded exclusively linear hydrocarbons by the HDO reaction. Furthermore, the NiMo/TiO2 was the most selective catalyst from the studied NiMo phases to n-octadecane, the product of octanoic acid hydrogenolysis: Pronounced isomerization and cracking activity during HDO was observed over NiMo/SiO2-Al2O3 catalyst.
