Summary

A sophisticated perturbation chromatography technique has been used to study the vapor-liquid equilibrium behavior of six light gases in two hydrogen-coal liquid model compounds systems. Infinite-dilution K values are reported for methane, ethane, propane, n-butane, carbon dioxide and hydrogen sulfide in: (1) hydrogen-dibenzofuran system at 373.2 and 398.2/sup 0/K and up to 6 MPa; and (2) hydrogen-g-methylanthracene systems at 373.2, 398.2, 423.2, 448.2 and 473.2/sup 0/K and up to 21 M Pa. Henry's constants were determined for the light gases in 9-methylanthracene. Second cross virial coefficients and vapor-phase infinite-dilution fugacity coefficients were calculated for the hydrocarbon gases in hydrogen. The results were combined with the experimental K-value measurements to obtain Henry's constants in hydrogen-9-methylanthracene mixtures of fixed liquid composition. The constants thus obtained show a significant dependence of hydrogen solubility. 1 reference.
