“…Isomerization processes consist of three types: (1) low-temperature reactions (120°C-180°C) are utilized for chlorinated alumina, (2) medium reactions temperature range (250°C-300°C) have been informed by using zeolites, and (3) high reaction temperature between (360°C-440°C) are promoted generally by fluorinated alumina [27]. The catalysts used in this work are employed widely in industrial operations at 130°C-180°C because these catalysts are based on chlorinated alumina [31]. Chlorinated alumina catalysts are the most active and provide the greatest yield of iso-alkanes, thus producing the highest octane number isomers Because of the gradual reduction of the acidity in the isomerization catalyst during the process (which decreases the isomerization activity), these reactions require the addition of alkyl chlorides to the feed.…”

Recently, the isomerization of light naphtha has been increasingly significant in assisting refiners in meeting sternness specifications for gasoline. Isomerization process provides refiners with the advantage of reducing sulfur, olefin, and benzene in the gasoline basin without significantly victimizing the octane. The mathematical modeling of a chemical reaction is a critical tool due to it can used to optimize the experimental data to estimate the optimum operating conditions for industrial reactors. This paper describes light naphtha isomerization reactions over a Pt/Al 2 O 3 -Cl catalyst at the Al-Dura Oil Refinery (Baghdad, Iraq) using a newly developed universal mathematical model. The proposed kinetic model involves 117 isomerization reactions and 90 cracking reactions to describe 52 real components graded from methane to n-octane. A Genetic Algorithm stochastic optimization technique applied in MATLAB R2020a software was employed to estimate the optimal set of kinetic parameters. The calculated activation energies for hydrocracking reactions was found to be higher than the other reactions because of hydrocracking reactions occur at higher range of temperatures. By benchmarking between the experimental and theoretical results for all 117 data sets, the mean absolute error was obtained to be 0.00360 for all 52 components. Also, a positive effect of increasing reaction temperatures was recognized on enhancing the research octane number (RON).
