Naphtha reforming on mono and bimetallic catalysts
Applied Catalysis, 1987Abstract Catalytic activity, selectivity and stability in the reforming of several naphtha cuts on Pt/Al 2 O 3 , Pt-Re-S/Al 2 O 3 and Pt-Ge/Al 2 O 3 were studied by carrying out activity-deactivation tests which consist of three periods. During the first and third periods, industrial conditions were reproduced, and during the second one, pressure ...

Kinetic Modeling of Naphtha Catalytic Reforming Reactions
Energy & Fuels, 2000In this work a kinetic model for the naphtha catalytic reforming process is presented. The model utilizes lumped mathematical representation of the reactions that take place, which are written in terms of isomers of the same nature. These groups range from 1 to 11 atoms of carbon for paraffins, and from 6 to 11 carbon atoms for naphthenes and aromatics.

A dynamic model for naphtha catalytic reformers
Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005A kinetics-based dynamic model for commercial naphtha fixed-bed catalytic reformers is developed in this paper. The dynamic model is composed of the reforming reaction model, the heater model and the separator model, which is capable to capture the major dynamics that occur in this process system.

XPS studies of Pt—Sn naphtha reforming catalysts
Applied Catalysis, 1990Abstract Pt—Sn has been supported on a nonporous (110 m2/g) alumina, a higher surface area (250 m2/g) porous alumina and a silica (700 m2/g). Both Sn (O) and Pt (O) have been observed in the reduced samples. Sn(O), and presumably alloy formation, occurs to a greater extent when platinum and tin are added as a complex dissolved in acetone as compared ...

Kinetic of Naphtha Catalytic Reforming. Influence of Space Velocity on Naphtha Composition Changes
Oil, gas (Hamburg), 1996In 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.
