Abstract:
The reaction mechanism for the heterogeneous catalytic cracking of an unsaturated fatty acid and unsaturated acylglycerides was studied. Oleic acid and mono-, di-, and triolein, acylglycerides with oleic acid as the fatty acid constituent were reacted at 400°C over H-ZSM-5 catalyst. The reaction products were identified using mass spectrometry and quantitated using thermal conductivity detector analysis. Selected products were further reacted in an effort to elucidate the reaction pathway for producing green fuels from unsaturated lipids. Results indicated initial cracking occurring at the double bond within the fatty acid chain. The shape-selective H-ZSM-5 catalyst promoted the production of aromatic compounds as tertiary cracking products. A reaction mechanism has been proposed. These results aid in the realization of using lipid feedstocks for transportation fuels.
