What Are the Common Types of Catalyst Deactivation?
There are several types of catalyst deactivation, including:
- Poisoning: This occurs when impurities in the feedstock bind to the active sites of the catalyst, rendering them inactive. - Fouling: Accumulation of carbonaceous deposits or other materials on the surface of the catalyst can block active sites. - Sintering: High temperatures can cause the active metal particles to agglomerate, reducing the surface area available for the reaction. - Thermal Degradation: Prolonged exposure to high temperatures can lead to a breakdown of the catalyst structure.
