Excuse my ignorance, I am neither a chemist nor an engineer. I am actually in finance trying to figure out product properties.
I am having hard time understanding how is it possible to have a >10psi RVP naphtha feed go into a catalytic reformer, and have a <4psi RVP reformate come out the other end?
My logic dictates the following:
1) The lighter the molecule (shorted hydrocarbon chain) the higher the RVP and lower the Octane (and vice versa)
2) Unsaturated molecules are more reactive and therefore will have higher RVP compared to saturated chains of equal carbon atoms.
The questions driving me nuts:
1) Why does alkylate which has more saturated content have higher RVP than reformate?
2) Is the reason for akly having lower RON than reformate the fact that its molecules are lighter than in reformate?
