Breakthrough Curves of Propane at Different Relative Humidities

In many separation processes, the adsorption of different components takes place in the presence of water. In fact, the competitive adsorption of water can have a tremendous influence on the separation performance of the adsorbents. This is important for waste air and indoor air cleaning but also for health protection gas masks.
However, often also the preconditioning of the samples has a large effect. The adsorption of propane in the presence of water was investigated on an activated carbon at 298 K and 1 bar with a flow rate of 4000 mL min-1 with a dynaSorb BT coupled with a Pfeiffer ThermoStar mass spectrometer.
