In order to study the sulfidation of a catalyst fixed bed, an in operando single pellet sensor was designed. A catalyst pellet from the fixed bed was electrically contacted and its electrical response was correlated with the catalyst behavior. For th

Recently, it has been shown that the degree of loading of several types of automotive exhaust aftertreatment devices can be directly monitored in situ and in a contactless way by a microwave-based method. The goal of this study was to clarify whether

This study reports on a sensor concept to measure in situ sulfur poisoning (sulfidation) of refinery catalysts, in this case, of commercial silica pellets loaded with highly dispersed nickel. Catalyst pellets were poisoned in diluted H2S between 100

The aim of this work is to study whether a contactless radio frequency-based method is suitable to monitor both coking and regeneration (coke burn-off) of industrial fixed-bed catalysts directly and in operando . The tubular steel reactor serves as a

Coke formation affects the activity of catalysts and the product spectra in refinery and petrochemical processes. In previous works, it was shown that the coke content in heterogeneous catalysts can be monitored in-situ by measuring the electrical im

The aim of this work is to investigate a novel contactless in-operando microwave-based measurement technique for the detection of coke deposits in industrial fixed-bed catalysts. Their steel reactors serve as cavity resonators for microwaves. Due to
