What are the Common Signs that a Catalyst Needs Updating?
Common indicators that a catalyst needs to be updated include:
1. Decreased Activity: A significant drop in reaction rates can suggest catalyst deactivation. 2. Lower Selectivity: An increase in undesired by-products may indicate changes in the catalyst's active sites. 3. Physical Changes: Observations of sintering, agglomeration, or structural breakdown can signal the need for replacement. 4. Increased Pressure Drop: In packed bed reactors, an increase in pressure drop might indicate catalyst fouling or clogging.
