Abstract: The paper presents new, absolute measurements of the viscosity and thermal conductivity of mixtures of hydrogen with carbon monoxide, carbon dioxide and methane near room temperature. The viscosity measurements have been performed at a pressure of 0.1 MPa and have an estimated accuracy of ±0.1%. The data have been employed to evaluate quantities characteristic of the unlike interaction, including the binary diffusion coefficient. These results allow the thermal conductivity to be calculated with the aid of the appropriate kinetic-theory expressions. The calculations have been performed for both the zero-density limit and over the range of pressures encompassed by the measurements (0.8–12 MPa). It has not proved possible to represent the experimental thermal conductivity data within their uncertainty of ±0.3% by means of the available kinetic-theory equations. This finding is attributed to the fact that the equations employed are not as accurate as the experimental data for systems in which the mass ratio of the species differs substantially from unity.
