we converted palmitic and oleic acids to fuel range hydrocarbons using two activated carbons in near and supercritial water with no H(2) added. The main products from palmitic acid were C(8)-C(15) n-alkenes. The major products from oleic acid were C(12)-C(17) n-alkanes and some C(17) olefins. The pseudo-first-order rate constants displayed Arrhenius behavior. The apparent activation energy displayed Arrhenius behaviour The apparent activation energy of 125 kJ/mol for palmitic acid decarboxylation is higher than that observed with a 5% Pt/C catalyst. Nevertheless, these results show that activated carbons possess catalytic activity for the hydrothermal decarboxylation of fatty acids.
