Understanding bulk heterogeneity is essential because it affects the overall performance of a catalyst in several ways:
Mass Transfer: Non-uniformities can create areas with different mass transfer rates, impacting the availability of reactants and removal of products. Thermal Conductivity: Variations in thermal properties can lead to hot spots or cold spots, affecting reaction kinetics and catalyst life. Mechanical Stability: Inhomogeneities may lead to mechanical stresses and eventual degradation or deactivation of the catalyst.
