Material loss can be attributed to several factors, including:
Thermal Degradation: High temperatures can cause structural changes in catalyst materials, leading to their breakdown. Mechanical Attrition: Physical wear and tear due to stirring, mixing, or fluid flow can erode catalyst particles. Poisoning: Impurities or by-products in the reaction mixture can bind to the active sites of the catalyst, rendering them inactive. Sintering: At elevated temperatures, catalyst particles can agglomerate, reducing the active surface area. Leaching: Soluble catalyst components can dissolve into the reaction medium, leading to material loss.
