Renewable hydrocarbons in the composition ranges of gasoline and diesel were prepared from palm oil through hydrolysis and oxidative cleavage followed by decarboxylation. Hydrolysis was conducted with water in a subcritical state to obtain saturated and unsaturated fatty acids from palm oil triglycerides. The hydrolysis product was treated with KMnO4 as an oxidizing agent to convert unsaturated fatty acids into short fatty acids by cleaving C=C double bonds. The obtained product was then decarboxylated with Pd/C catalyst under N2 pressure to produce hydrocarbons, including gasoline and diesel fractions. This work demonstrated the potential of palm oil as a source of renewable fuels, providing about 21 wt.% gasoline hydrocarbons and 48 wt.% diesel hydrocarbons based on palm oil as the feedstock.
