Thermal expansion can lead to several issues in catalytic processes:
Structural Integrity: Changes in volume can cause mechanical stress, potentially leading to the cracking or breaking of catalyst supports. Altered Pore Structure: The pores within a catalyst may expand or contract, affecting the diffusion of reactants and products. Thermal Stability: Catalysts that are not thermally stable may experience sintering, where particles agglomerate, reducing the active surface area.
