| Abstract: | In this work, a new potential route to convert free fatty acids to long chain nitriles and fuel gas (H2/hydrocarbon) intermediated by Fe nitrate is proposed. Precursors based on Fe³+/RCOO-/NO3- were prepared by mixing Fe nitrate and oleic acid at the molar ratios 1:1 and 1:3. After pyrolytic decomposition at 550 °C, these precursors yielded three fractions, i.e. solid (8−27 wt%), liquid (22−51 wt%) and gaseous (41−51 wt%). TG, XRD, SEM, Raman, Mössbauer, CHN analyses of the solid products showed the presence of 25–52% carbon with reduced iron oxides (Fe3O4 and FeO). Analyses of the liquid fraction by GCMS, ¹H/¹³C–NMR, CHN and FTIR clearly indicated the formation of nitriles as the main products, with selectivity of ca. 80 % and small amounts of hydrocarbons and ketones. A large gas fraction composed mainly by hydrogen and hydrocarbons (especially C3) was also formed. |
