Abstract. The paper describes the results of mathematical modelling of diesel fuel catalytic dewaxing process, performed taking into account the factors of process nonstationarity driven by changes in process technological parameters, feedstock composition and catalyst deactivation. The error of hydrocarbon contents calculation via the use of the developed model does not exceed 1.6 wt.%. This makes it possible to apply the model for solution to optimization and forecasting problems occurred in catalytic systems under industrial conditions. It was shown through the model calculation that temperature in the dewaxing reactor without catalyst deactivation is lower by 19 o C than actual and catalyst deactivation degree accounts for 32 %.

“…Chuzlov and colleagues − have developed a rigorous mathematical basis for both extracting kinetic information from experiments and also using kinetics information in the simulation of isomerization processes. Chuzlov et al summarized the catalytic reaction mechanism, the associated active centers, and the derived molecular transformations of the isomerization reactions over a Pt over sulfated zirconia catalyst in the context of a full set of material and energy balance equations.…”

Catalytic Upgrading of Light Naphtha to Gasoline Blending Components: A Mini Review

et al. 2019

The upgrading of light naphtha (C5–C6 stream) to gasoline blending components has been the subject of intensive research at both academic and industrial laboratories. The combination of high volatility and low-octane number has made this stream surplus at many refineries worldwide. This review presents the latest developments in selected catalytic upgrading processes and a brief discussion on the reaction mechanism and reactor models. A majority of the review falls within the development of catalysts for n-hexane isomerization to hydrocarbon isomers with a high octane number. There are three types of isomerization catalysts that include Pt/Al2O3–Cl, Pt/SO4–ZrO2, and Pt/zeolite. Efforts are ongoing to improve the catalyst performance for higher selectivity and catalyst lifetime. Very little work has been published on the conversion of n-pentane mainly as a result of its low activity and the limited options available for its transformation to gasoline blending components. Other approaches discussed in the review include dimerization and oligomerization of C5–C6 alkenes and methylative homologation. The review covers literature published during the period of 2000–2018.

“…It should be noted that the accuracy of calculations and the adequacy of the mathematical model to the actual process directly depend on the degree of detail of chemical transformations. Therefore, the transformation scheme should sufficiently reflect the physico-chemical nature of the process [6,7]. In this article there was an attempt to make more detailed analysis of the scheme of reaction networks proceeding from the mechanism.…”

The article examines main schemes of reaction networks of the catalytic isomerization of the pentane-hexane fraction. The selection of the kinetic model for the most complete description of the basic chemical processes based on the mechanism of the reactions proceeding is substantiated. The mathematical model is constructed on the basis of kinetic model. The foundations for the subsequent modeling of the entire chemical-technological process system are laid.
