Abstract in another language

The aim of this work is to develop a sensor concept that detects in-situ the sulfur poisoning level of a fixed bed catalyst during deactivation by sulfur compounds. Therefore, single catalyst pellets are contacted and their electrical impedance is measured directly in the reactor. Since sensor pellets and catalyst particles in the fixed bed are identical, it can be assumed that the sulfur affects the sensor and the catalyst particles the same way at equal test conditions. The impedance of the sensors in the unloaded state is in the range of some M and decreases continuously by decades as soon as hydrogen sulfide is added to the gas stream. Using a product gas analysis, the sorbed sulfur mass can be calculated through a mass balance. In order to verify the data, also weighing experiments are conducted with the fixed bed. In addition to these techniques, XRD and EDX measurement are used to analyze the exact way of sulfur poisoning.
