ENTHALPIES OF THE HYDROGEN-LIGHT HYDRO-CARBON BINARY MIXTURES AT ELEVATED PRESSURES AND LOW TEMPERATURES

[摘要] References(21)The enthalpies of hydrogen-methane, hydrogen-ethane, and hydrogen-propane mixtures were measured by flow calorimetry at several temperatures from 120 K to 210 K and 6.8 atm and 13.6 atm. The experimental data ranged in the vapor and vapor-liquid coexisting regions. By adopting the previously proposed estimation method of hypothetical liquid properties of hydrogen, the regular solution theory could be successfully applied to predict the enthalpies of hydrogen-light hydrocarbon mixtures in vapor-liquid coexisting region.
