← ScienceWhich consequence results when a catalytic converter's porous support structure becomes heavily fouled by silicone?
A)Reduced exhaust gas contact time✓
B)Increased catalyst surface area occurs
C)Lower activation energy is required
D)Increased precious metal dispersion occurs
💡 Explanation
Fouling reduces flow through the catalyst, because pore blockage reduces the surface area available for reaction; therefore the gases have less contact time with the catalyst, rather than enabling increased precious metal dispersion.
