| Abstract: | A multicomponent vapoflow calorimeter made of metals was constructed in this laboratory. The apparatus was calibrated by benzene, the standard substance,the error of which was less than 0.7% at the temperature range from 350K to 700K.The vapor heat capacities at various temperatures for 14 petroleum fractions, the typical complicated hydrocarbon mixtures,were measured for the first time. The relationships for the capacity and temperature, the physical properties of fractions were discussed.The corresponding empirical equations were then given.The results estimated by the API method were also compared with the experimental data. |
