Determination of Freezing Point of High-Density Hydrocarbon Fuels by Differential Scanning Calorimetry

Principle and method of measuring freezing point of high-density hydrocarbon fuels by differential scanning calorimetry (DSC) are introduced, and the main influence factors during testing are discussed. The result shows that DSC method has good repeatability and reproducibility, can be used as an routine measuring method for the low freezing point fuels such as high-density hydrocarbon and so on when the freezing point of high-density hydrocarbon fuels is below -80℃.
