The thermal shock resistance of a catalyst can be tested using various methods. Some of the most common techniques include:
Quenching Tests: This involves rapidly heating the catalyst to a specific temperature and then quickly cooling it by immersion in a cold fluid, such as water or air. The number of cycles the catalyst can endure before showing signs of damage indicates its thermal shock resistance. Thermal Cycling: This method subjects the catalyst to repeated cycles of heating and cooling. The temperature range and the number of cycles can be adjusted to simulate real-world operating conditions. Mechanical Testing: After thermal cycling or quenching, the catalyst's mechanical properties, such as tensile strength and hardness, are measured to assess any degradation due to thermal shock.
