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 carried out 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.
