Several factors can contribute to the reduced lifespan of a catalyst:
Poisoning: This occurs when impurities in the reactants or environment bind to the active sites of the catalyst, rendering it inactive. Sintering: High temperatures can cause catalyst particles to agglomerate, reducing the surface area available for reactions. Coking: The buildup of carbon deposits on the catalyst surface can block active sites and reduce effectiveness. Leaching: In liquid-phase reactions, the active components of the catalyst can dissolve into the solution, leading to loss of activity. Thermal Degradation: Prolonged exposure to high temperatures can change the physical and chemical properties of the catalyst.
