Naphtha Mid-Continent

The C7 rate coefficients were determined from a C6- 372 K Mid-Continent naphtha which contained only C6 and C7 components. 

KINPTR simulations of commercial reforming (Table XVIII) will be used in this section to demonstrate process sensitivity. In the base case, a full-range Mid-Continent naphtha (55 wt. % paraffins) is reformed to a constant octane of 90 R + 0 over the entire cycle. With a reactor pressure of 1695 kPa and a 7.2 H2 recycle ratio, the start-of-cycle reactor inlet temperature to achieve target octane is predicted to be 759 K. The deactivation simulation shows that it would take about 1 year to reach the end-of-cycle temperature of about 798 K. The start-of-cycle C5+ yield for this case is 86 vol %. The model predicts that the yield would decline by 4.8 vol % over the cycle.
