Abstract

We developed a surrogate mixture model to represent the physical properties of a coal-derived liquid fuel using only information obtained from a gas-chromatography-mass spectrometry analysis of the fuel and a recently developed ¿advanced distillation curve¿. We then predicted the density, speed of sound and viscosity of the fuel and compared with limited experimental data. The surrogate contains five components (propylcyclohexane, trans-decalin, ¿-methyldecalin, bicyclohexane and n-hexadecane) yet comparisons with limited experimental data demonstrate the model is able to represent the density, sound speed and viscosity to within 1 %, 4 %, and 5 %, respectively.
