A study of the kinetics of catalyst decay in the presence of a wax‐free and of a waxy feed has shown that the wax‐free feed causes decay by the poisoning of one site at a time whereas the waxy feed shows that wax poisons catalyst activity by competing one and two site mechanisms. In all these mechanism decay proceeds partly and perhaps totally by reactions involving two molecules of poison per deactivation event.
