Vanadium leaching can be caused by several factors:
1. Chemical Interaction: The reaction medium, particularly if it is acidic or basic, can dissolve vanadium species from the catalyst. 2. High Temperatures: Elevated temperatures can accelerate the leaching process by increasing the solubility of vanadium compounds. 3. Mechanical Stress: Physical wear and tear on the catalyst can expose more vanadium to the reaction environment, enhancing leaching.
