Thermal conductivity of pure gases were correlated by means of an extended form of the modified Enskog theory together with a modified volume-translated Peng-Robinson equation of state at low temperatures and at pressures up to 370 bar. Two different approaches were used in the correlation. A substance and temperature dependent parameter was introduced in both correlations. The pure-component parameters thus obtained were used to predict the thermal conductivity of five binary mixtures (Ar-He, Ar-N2, Ar-Ne, He-N2 and N2-Ne) without using any binary adjustable parameters with various degrees of success.
