Breakthrough curves on carbon molecular sieves – experiment and modeling using 3P mixSorb

The dynamic method for the measurement of gas adsorption breakthrough curves is necessary to esti­mate kinetically controlled sorption processes which cannot be predicted by thermodynamic simulation. The 3P Instruments mixSorb L can be used for such practical investigations to obtain relevant data for kinetically controlled pure and mixed gas sorption dependent on temperature, pressure and gas flow. The 3P sim simulation software is able to provide the cor­rect thermodynamic prediction of the breakthrough curves by use of equilibrium isotherms of the compo­nents.
