Measuring the Soret coefficient of binary hydrocarbon mixtures in packed thermogravitational columns (contribution of Toulouse University to the benchmark test)

Within the framework of an international benchmark test, our group which researches packed thermogravitational columns has measured the porous medium thermodiffusion coefficient D-T(*) of two hydrocarbon binary mixtures: tetrahydronaphthalene-dodecane and tetrahydronaphthalene-isobutylbenzene. The weight fraction of each component was near 50 wt%.
