The active lifetime of a catalyst in a reactor is critical to running a process. The authors studied the deactivation of a commercial palladium‐supported catalyst by hydrogen sulfide (H 2 S) and were particularly interested in the mechanism of the deactivation. Measuring the adsorption of the H 2 S gravimetrically and using XPS, the authors propose various types of sulfur containing compounds on the deactivated surface.
