ABSTRACT

An experimental study of temperature dependence of binary diffusion coefficients was conducted for five binary mixtures of gases: H2-N2, H2-CO, H2-CH4, H2-C2H6, H2-C3H8 in the range of temperatures 250 / 900 K and pressures 0,1 / 15 MPa. The measurements were made by a steady flow method. The experimental data were compared with the results of calculations by the proposed formula. It is shown in the paper that the calculations obtained within the framework of the elementary kinetic theory have considerably good agreement with the experiment within the experimental error.
