Thermodynamic and rheological properties of solid-liquid systems in coal processing
Abstract
None of the models available in the literature are known to work very well for aromatic compounds such as the ones that occur in coal derived materials. Two models - one by Van Velzen et al. (Ind Eng. Chem. Fundam. Vol 11, 1972, pp. 20-25) using a group contribution method and the other by Hwang et al (Ind. Eng. Chem. Process Des. Dev., Vol. 21, 1982, pp. 127-134) using a corresponding states method - were tested for some typical compounds that occur in coal liquids. These methods give errors ranging from 10 to 50% for viscosities of such compounds. These errors are too high and considering further errors in extension of these models to coal liquids, these models were considered unacceptable in our work. We have therefore set out to develop a new model for viscosities of aromatic compounds. We plan to base the model on the procedure similar to that of Van Velzen, however developed for just aromatic compounds. Our model, once developed will therefore be a group contribution method centered around the benzene ring structure.
