followed by the
hydrogenolysis of saturated triglycerides resulting in fatty acids
and propane. Finally, the fatty acid undergoes the following reactions:
(1) HDO, an exothermic reaction, to remove oxygen in the
form of water and yield n-alkane with the same carbon number
as the corresponding fatty acid, and (2) DCO and (3) DCO2, endothermic
reactions, to eliminate oxygen in form of CO and water
or CO2, respectively. The consequent n-alkane has one carbon atom
loss compared to the original fatty acid
