Catalytic Naphtha Reforming

Catalysis Reviews, 1972
Abstract During the past twenty years, the demand for high octane motor fuels has resulted in the installation of catalytic naphtha reforming capacity at a much higher rate than was forecasted by some of ...

Naphtha steam reforming for hydrogen production

Catalysis Today, 2005
A study based on hydrogen production by catalytic naphtha steam reforming is presented. Reaction product composition depends on process conditions, which govern the equilibrium of gas species. This study has been realized in a fixed-bed-type reactor with a commercial steam reforming nickel catalyst and with a series of catalysts obtained by thermal ...

Modelling of catalytic naphtha reformers

The Canadian Journal of Chemical Engineering, 1989
AbstractA simple kinetic model has been used to simulate catalytic naphtha reformers. The model idealises naphtha to three constituents, namely, paraffins, naphthenes and aromatics, with average properties assigned to each class. Out of the many reactions the mixture can undergo, four major reactions have been considered for which the kinetic ...

Chlorination ofPtReAl2O3 During Naphtha Reforming

Journal of Chemical Technology & Biotechnology, 1996
The reforming of a paraffinic naphtha was studied in order to determine the influence of chlorination during the run. Experiments were performed at 505°C, 15 kg cm -2 , WHSV = 4, H 2 : HC = 4, and with or without an 8 h initial period of deactivation at 1 kg cm -2 .

Catalytic Naphtha Reforming

2017
Catalytic naphtha reforming (CNR) process was pioneered by UOP in the late 1940s to meet the burgeoning demand for high-octane motor fuels and has been a pivotal unit in petroleum refineries all over the world since its inception. The CNR process is specifically designed to convert naphtha to high-octane gasoline blending components called reformate ...

Naphtha reforming kinetics—methane selectivity

Chemical Engineering Science, 1983
Abstract The production of methane by steam-reforming of naphtha involves both rate controlling formation of carbon monoxide and hydrogen, followed by near equilibrium reactions of carbon monoxide with steam and hydrogen. In this paper a model is proposed for predicting the composition of the product gas for a single, isothermal/catalyst particle ...

Accelerated deactivation tests in naphtha reforming

Applied Catalysis, 1986
Abstract The nature of coke obtained by means of an accelerated deactivation test and that produced in a plant during naphtha reforming are compared. The accelerated deactivation test includes three periods; different amounts of carbon, in the same order as those obtained in plant, can be produced if the pressure is decreased consistently during the ...

Prediction of catalyst stability in naphtha reforming

Journal of Chemical Technology and Biotechnology, 1982
AbstractA method to predict catalyst activity (RON) and selectivity (ηc5+, liquid yield) of naphtha‐reforming catalysts during normal operation is described. It involves performing experiments at normal operational conditions and testing accelerated deactivation. These last experiments have a severe intermediate period at lower pressure.

Reforming of Naphtha Cuts in Small Plants

Chemistry and Technology of Fuels and Oils, 2001
It is advantageous to construct small distillation plants and reforming units that operate on oxide catalysts (zeolite–aluminosilicate, zeolite, etc.) without circulation of hydrogen in the reaction system for production of high-octane naphthas from crude oil or gas condensates in the conditions of the Far North, Siberia, and the Far East.
