Several factors can induce mechanical stress in catalytic systems:
- Thermal Expansion: Rapid temperature changes can cause the catalyst material to expand or contract, leading to internal stresses. - Pressure Fluctuations: Changes in pressure, especially in gas-phase reactions, can exert stress on the catalyst. - Mechanical Vibrations: Equipment vibrations can transfer mechanical energy to the catalyst, causing wear and tear. - Chemical Reactions: Some reactions can generate by-products that exert physical stress on the catalyst material.
