摘要：

A correlation formula to estimate chemical exergies of oil fractions and fuel mixtures from enthalpy of combustion and atomic composition is developed. Heat capacity of a mixture of 10 hydrocarbons was measured in the range 5-290 K. It was shown that contribution of entropy of mixing to exergy of typical oil fractions is about -0.11% in the approximation of ideal solution, and about -0.18% for a real solution.
