Biofuels energetics: Measurements and evaluation of calorific values of triglycerides

The triglycerides with the saturated alkyl chains containing 3, 4, and 6 carbon atoms, as renewable energy sources were investigated. Specific energies of combustion were measured by using high-precision combustion calorimetry. The standard molar enthalpies of combustion and formation were derived from these results. Validation of the new calorific data for triglycerides was performed using the structure-property relationships. The experimental and additive enthalpies of formation for triglycerides measured in this work agree well and could be recommended for the thermochemical calculations for triglyceride technologies.
