Web2.16.2.4.1 Poisoning. The fundamental reason for catalyst poisoning is the interaction between a component existing within the feed or product and the active sites of the catalyst. In this respect, poisoning is a chemical phenomenon, whose severity is positively correlated with time (Fig. 10 ). Palladium belongs to group 10 in the periodic table, but the configuration in the outermost electrons is in accordance with Hund's rule. Electrons that by the Madelung rule would be expected to occupy the 5s instead fill the 4d orbitals, as it is more energetically favorable to have a completely filled 4d shell instead of the 5s 4d configuration. This 5s configuration, unique in period 5, makes palladium the heaviest element having only on…
