Equilibrium and volumetric data and model development for coal fluids. [Quarterly report], April 15, 1991--July 15, 1991
During the present reporting period, experimental measurements were obtained on the solubility of carbon monoxide (CO) in selected hydrocarbons using our static type equilibrium cell. Binary mixtures involving CO + n-eicosane (n-C{sub 20}), n-octacosane (n-C{sub 28}), and n-hexatricontane (n-C{sub 36}) were studied at temperatures from 323.2 to 423.2 K and pressures to 104 bar. These data were analyzed using the Soave-Redlich-Kwong and Peng-Robinson equations of state. While a single interaction parameter, C{sub ij}, describes the n-C{sub 20} and n-C{sub 28} measurements within 0.004 in mole fraction over the full temperature range, temperature dependent parameters are required to adequately fit the n-C{sub 36} data. The present data are in reasonable agreement with the earlier measurements of Huang and coworkers in general, deviations within 0.004 in mole fraction are observed.
