Heat capacity of coal liquids

Abstract

The experimental procedure and techniques are described for using differential scanning calorimetry to obtain accurate liquid heat capacities of organic materials, particularly coal liquids, at high temperatures. The heat capacity of coal liquids produced by the Exxon Donor Solvent process was determined at temperatures up to 404 F. Measurements were also made up to 530 F on the heat capacity of defined compounds found in coal liquids. These results were used to develop correlations for predicting the liquid heat capacity of coal liquids.
