Several factors can influence the bulk crush strength of a catalyst:
1. Material Composition: The chemical composition and phase structure of the catalyst material can significantly impact its mechanical strength. 2. Particle Size and Shape: Uniformity in particle size and shape often leads to more consistent crush strength. 3. Manufacturing Process: The methods used in forming and calcining the catalyst can affect the porosity and density, thereby influencing crush strength. 4. Aging and Degradation: Exposure to reactive environments and thermal cycling can weaken the catalyst over time, reducing its crush strength.
