Solvent Refined Coal (SRC) process. Selected physical, chemical, and thermodynamic properties of narrow boiling range coal liquids for the SRC-II process. Interim report, March 1980-February 1981
Physical, chemical, and thermodynamic properties of coal liquids as a function of boiling range via the pseudocomponent approach are needed for process design now that various direct coal liquefaction processes are being scaled to semi-commercial size. Products from the SRC-II processing of a high volatile bituminous coal were distilled into narrow boiling fractions with average boiling points ranging up to 969/sup 0/F. Fractions boiling below 750/sup 0/F typically spanned a 50/sup 0/F interval, while the others were slightly wider boiling and overlapped somewhat. Liquid density, thermal conductivity and viscosity were measured at temperatures to 450/sup 0/F, and specific heat was determined at temperatures near the boiling point of each fraction. Other property determinations included molecular weight, pour point, elemental analyses, water content and solubility and hydrocarbon types. Both organic oxygen content and water solubility showed a pronounced maximum for the fraction having an average boiling point of 384/sup 0/F. This fraction showed anamolous density and thermal conductivity behavior. A secondary distillation on six different fractions spaced over the entire boiling range yielded heart cuts spanning 8 to 46/sup 0/F that were used for measurement of surface tension, heat of vaporization and vapor pressure at temperatures to 900/sup 0/F. Property data for all the fractions are compared with other published data and existing property correlations.
