摘要
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.
