Thermoosmosis of ternary mixtures of oxygen, nitrogen, and carbon dioxide across a porous unglazed membrane has been studied, The thermoosmotic pressure difference, ΔP, created by a temperature difference, ΔT, has been measured at various mean temperatures and pressures. Experimental data have been interpreted in the light of non-equilibrium thermodynamics of irreversible processes and the dusty gas model of Mason. Heats of transport for the mixtures, Q, filled, have been estimated from the measured values of pressure difference and temperature difference. It is found that the heat of transport of mixtures is independent of the mean temperature and temperature difference as was found in earlier studies on multicomponent mixtures.
