How Does Shear Sensitivity Affect Catalyst Performance?
Shear sensitivity can impact catalyst performance in several ways:
1. Structural Integrity: High shear forces can lead to the physical breakdown of catalyst particles, resulting in loss of surface area and active sites. 2. Dispersion Stability: Shear forces can affect the dispersion stability of supported catalysts, causing aggregation or settling of the active phase. 3. Mass Transfer: Changes in the microstructure of the catalyst due to shear forces can alter mass transfer properties, affecting reaction kinetics. 4. Deactivation: Mechanical degradation can expose the catalyst to poisons or result in the leaching of active components, leading to deactivation.
