How Do Spatial Temperature Variations Affect Catalytic Performance?
Temperature variations can have several impacts on catalytic performance:
Reaction Rates: Catalytic reaction rates are temperature-dependent. Variations can lead to uneven reaction rates, impacting overall efficiency. Selectivity: Different temperatures can favor different reaction pathways, affecting the selectivity of the desired product. Catalyst Deactivation: Hot spots can cause thermal degradation or sintering of the catalyst, leading to deactivation. Safety: Extreme temperature variations can pose safety risks, such as thermal runaway reactions.
