Samenvatting

Volatile Organic Compounds (VOCs) are one of the most widespread causes of environmental pollution. Despite their low concentration in the surroundings, these compounds are often associated with severe health issues and represent a threat against environmental sustainability. Hence, the development of efficient VOCs removal systems has become a priority in the field of chemical engineering. Physical adsorption of VOCs from gas phase comes with great ambitions in the context of pollutants removal and gas cleaning processes, as it provides analogous results to traditional methods with considerable gain in terms of energy consumption. However, due to the very low concentration of those compounds, the study of adsorption dynamics of such system suffers serious problems concerning the limits of the detection system, especially for the mixtures. This comes with the necessity of developing new strategies to achieve higher experimental sensitivity, allowing for traces gas adsorption experiments in such extreme conditions. In this work, we propose an innovative methodology to perform vapor phase adsorption breakthrough experiments at ppm and sub-ppm concentration, by coupling Selected Ions Flow Tube Mass Spectrometry (SIFT-MS) with a custom vapor phase adsorption experimental apparatus. Multi-component adsorption breakthrough profiles of quaternary vapor phase mixtures (ethanol, ethyl acetate, 2-butanone and 2,3-butanedione) were studied on two different adsorbent materials (ZIF-8 and UiO-66), selected form the group of Metal-Organic-Frameworks (MOFs). The proposed experimental system not only outclasses conventional detection apparatus limits, but also bears significant advantages as the adsorbed species into the stream undergoes both separation and quantification in real-time, opening to novel attractive opportunities in the ground if the adsorption research.
