Heat dissipation is vital for several reasons: 1. Catalyst Stability: Excessive heat can degrade the catalyst, reducing its effectiveness and lifespan. 2. Reaction Control: Many catalytic reactions are exothermic. Without proper heat management, runaway reactions might occur, leading to safety hazards. 3. Selectivity and Yield: Temperature fluctuations can affect the selectivity and yield of the desired product, making heat dissipation essential for optimal performance.
