← ScienceWhich risk increases when molecular sieve beds overheat?
A)Exothermic polymerisation reactions occur✓
B)Increased bed pressure drop forms
C)Adsorbent water capacity increases
D)Selective component adsorption reduces
💡 Explanation
Overheating can cause exothermic polymerisation reactions because thermal energy overcomes activation barriers, accelerating propagation, therefore runaway reactions occur rather than controlled sieving or adsorption changes within design parameters.
