Abstract in another language

The activity of heterogeneous catalysts in refinery processes is substantially influenced by formation of coke deposits. This study expands an in-situ method for direct determination of the coke loading in fixed bed catalysts by utilizing suspension balance techniques. Here, it is investigated whether it is possible to measure the coke content during coking and regeneration. Applied to a technical relevant Al2O3-based Cr2O3-catalyst, it is shown that the electrical impedance of a catalyst pellet is strongly correlated with its degree of coke loading.
