Mechanical damage can occur during various stages of the catalyst lifecycle, including manufacturing, handling, transportation, and during the catalytic process itself. Factors contributing to mechanical damage include:
- Abrasion: Repeated frictional contact between catalyst particles or with reactor walls. - Attrition: Chipping or breaking off of small pieces from the catalyst surface. - Crushing: High-pressure conditions causing deformation or breakage. - Thermal Stress: Rapid temperature changes leading to expansion and contraction, which can cause cracking.
