During an inspection, several key components should be evaluated:
1. Physical Condition: Check for any physical damage to the catalyst bed or reactor. 2. Activity Level: Measure the activity of the catalyst to ensure it is performing as expected. 3. Selectivity: Analyze the selectivity to ensure the catalyst is producing the desired products. 4. Pressure Drop: Monitor the pressure drop across the catalyst bed to detect any blockages or fouling. 5. Temperature Profile: Ensure the temperature profile is consistent with the expected performance.
