Experimental Measurements of Molecular Force Parameter for Ar-CO2 Gas Mixture

A binary mixture of Ar-CO2 with equal percentage was used in the thermal diffusion column. A set of different temperature and pressures were applied. Through the operation of separation, the separation factor and the thermal diffusion factor were calculated. The molecular force parameter was calculated through a special computer program using the well known Lennard-Jones (12-6) molecular model. The results are in agreement with those extracted from viscosity measurement.
