Abstract The experimental determination of heating values of vegetable oils and animal fats can be determined based on simple proximate analysis data including fixed carbon, volatile matter, yield of distilled liquid, and ash contents which can be obtained relatively easily by using common laboratory equipment. The higher heating value (HHV) (MJ/kg) of the triglyceride sample as a function of the yield of distilled liquid (D, wt%) can be calculated from: According to Eq. (2), higher heating value is a function of the yield of distilled liquid of the dry and ash-free basis. Equation (2) represents the correlation obtained by means of regression analysis. The correlation coefficient is 0.9568.
