In a fixed bed semi regen. bimetallic Pt Re reformer catalyst with a target severity 90 RONC for HOBC production, as the cycle proceeds and catalyst ages, what is impact of catalyst ageing on GC of platformer stabilizer column (Debutanizer) off gases?

With aging following happens:
1- Hydrogen purity of RG falls.
2-Quantity of Stabilizer off gas increases by about 1 to 1.5 % on Feed basis. 3- Vol % of Hydrocarbon gases like C3 and C4 increase slightly.
3- Major effect is seen in hydrogen purity of RG which may fall by 6 to 7 % vol at cycle end

The quantity of the stream increases due to more hydrocracking at constant RON, but I believe the composition changes very little.
