Summary:Title screen
Background: A new approach for the simulation of branched hydrocarbons synthesis on platinum catalysts is provided. The kinetic and thermodynamic laws of low-temperature pentane-hexane fraction isomerization were established and studied. According to the performed research, development of hydrocarbons conversion mechanism on Pt/SO4-ZrO2 catalyst was provided.Objective: The objective of this work is to design the comprehensive mathematical model of isomerization as a tool for real process optimization.Method: This method is based on reactivity of components while prone to changes in the feedstock composition. Validation of the mathematical model of industrial light naphtha isomerization unit was done with industrial data. The proposed model showed satisfactory prediction ability.Results: Changes in feedstock composition correspond to 1 – 1.5 RON change in product. Temperature rise at the inlet of first isomerization reactor above 150 °C leads to a shift of the equilibrium towards the hydrocracking side reactions. Increasing loading of feedstock for every 2500 m/h reduces RON of isomerate by 0.43-0.5 points depending on the feedstock composition.Conclusion: The formalized reaction scheme was developed on basis of thermodynamic analysis for isomerization of light gasoline fractions. The kinetic parameters for different types of isomerization catalysts: Pt/SO4-ZrO2, Pt/zeolite, Pt/Al2O3-CCl4 were determined by solving reverse kinetic problem. The developed model for isomerization reactor was validated with industrial data and has satisfactory accuracy.
