Abstract
|
A new
trend in catalytic naphtha reforming requires the decrease of aromatics
hydrocarbons particularly benzene in reformate, while maintaining high octane
rating. At present, production of reformulated gasoline with low content of
benzene is one of the main challenges in the transportation fuel industry. In
the catalytic reforming of realistic naphtha over bi-functional
Pt-Re-S/Al2O3-Cl catalysts the: (i) liquid yield (C5+), (ii) yield of
aromatics, (iii) iso-paraffin/aromatics ratio, (iv) side reactions
(hydrocracking, hydrogenolysis, coking) as responses can be altered by
controlling the independent reaction parameters (Temperature, Pressure,
Liquid Hourly space velocity (LHSV), Hydrogen to hydrocarbon ratio (H2/HC
ratio), chlorine and the addition of different promoters to the catalyst (Re,
Sn, Ir, etc). In the present report, a quadratic polynomial equation for the
responses Research Octane Number (RON), Neglect this statement as these
models has been removed were obtained by multiple regression analysis and
tested using analysis of variance (ANOVA) with 95% degree of confidence.
The
validation of experimental data was confirmed with the predicted model. The
results showed that the reaction temperature and the total operating pressure
are the key variables that have the main influence on naphtha reforming
reactions by the synergistic effect of linear term (X1, X2), which is in a
good agreement with the experimental data reported previously in the
literature.
