Two different reactors were used to gather information about the kinetics of promoted potassium carbonate solutions for CO2 capture from flue gas. A bubble reactor was used to enable the fast evaluation of a wide rang of different solutions under a defined variation of experimental parameters as temperature and gas flow rate. Apart from the documentation of the CO2 absorption rate the bubble reactor also provided the possibility of a simultaneous documentation of the pH-value of the evaluated solution during the absorption process. These experiments underlined that the pH-value can be used as an indicator for the loading of a known solution during a absorption process. Secondly a wetted wall column reactor was used to obtain kinetic data of gas molecules on a clearly defined liquid surface. A variation of the experimental parameters as pressure, temperature and composition of the phases enables a process -steering in and out of chemical equilibrium.
