Modelling and simulation of commercial catalytic naphtha reformers

The Canadian Journal of Chemical Engineering, 1997
AbstractA simulation model for catalytic reforming has been developed to monitor commercial plant performance. The model consists of various modules to predict temperature and concentration profiles, catalyst deactivation and cycle length, inter stage heater duties, recycle gas composition and octane number. The lumping details of the feed and reaction

Fractal aspects in the catalytic reforming of naphtha

Chemical Engineering Science, 1996
Abstract An industrial catalytic reforming unit was simulated, accounting for the fractal morphology of the internal surface of the porous PtRe/Al2O3 catalyst. The reaction network consists of 86 reactions, with Hougen-Watson kinetics between 29 lumps. Diffusion and reaction inside the catalyst particles was rigorously simulated, solving the complete

Catalytic Reforming of Heavy Naphtha- Modeling and Simulate

International Science and Technology Journal
Catalytic reforming is a chemical process used to convert low-octane naphtha's into high-octane gasoline blending components called reformates to be used either as a motor fuel blending stock or as a source for specific aromatics, such as benzene, toluene and xylene (BTX).

ADVANCES IN THE CHEMISTRY OF CATALYTIC REFORMING OF NAPHTHA

Fuel Science and Technology International, 1991
Catalytic reforming of naphtha remains the key process for production of high octane gasoline and aromatics (BTX) which are used as petrochemicals feedstocks. The increased demand for these products has led refiners to investigate ways for improving the performance of the reforming process and its catalysts.

Toward enhanced hydrogen production in a catalytic naphtha reforming process

International Journal of Hydrogen Energy, 2012
Abstract Environmental regulations imposed on transport fuels, especially specifications on sulfur and nitrogen content, generally boost hydrogen requirements in refining industries. The catalytic naphtha reformer (CNR) process is one of the major sources of hydrogen in naphtha refinery, thus improving its hydrogen production would be of great ...

Kinetic of Naphtha Catalytic Reforming. Influence of Space Velocity on Naphtha Composition Changes

Oil, gas (Hamburg), 1996
In order to develop a kinetic model of reforming reactions the influence of space velocities on the change in composition of whole naphtha was studied. The activity of two commercial Pt-Re/Al2O3 catalysts (R-16 G and R-62) was tested in a pilot plant at space velocities 2.5-5.4 h-1, hydrogen: hydrocarbon mol ratio 5:1 and temperature 505 C.
