Diffusion in CO2–CH4 Mixtures to 225 Atmospheres Pressure

摘要: Diffusion coefficients have been measured in two mixtures of CO2 and CH4. (1) 50 mole percent CO2—50 CH4; (2) 75 CO2—25 C14 tagged was used, so that no gradient chemical composition necessary. For the first mixture results agreed with Enskog's dense gas theory at all temperatures pressures. 25°C there a positive deviation from theory, corresponding to increased importance glancing collisions for near saturation. The are consistent our previous data self‐diffusion pure gases.
