Peng-Robinson equation of state was modified to represent vapor-liquid equilibria tor hydrogen-hydrocarbon binary systems. A new expression of the temperature dependent parameter for the supercritical gas hydrogen
and binary interaction parameters were introduced to improve description of vapor-liquid equilibria for 19 binary systems. Results show that this work is superior to previous researches
and to Mathias RKS and CCOR equation of state for heavy hydrocarbons
C6 to C16
in particular. Moreover
estimations of p-V-T relation and second virial coefficients of hydrogen from our modification are in good agreement with the experimental data.
