“…A widely known classification distinguishes between low-, mid-, and high-temperature isomerization catalysts. The first applies to highly chlorinated alumina catalysts; the second applies to sulfated zirconia catalysts; and the third applies to zeolite–platinum catalysts …”

“…The key catalyst parameter is the strength of acid sites, because stronger acidity allows for operation at lower reaction temperatures, which is beneficial from the thermodynamic point of view. 19 Shakun et al 20 argued that the classification of various isomerization catalysts should be made based on their chemical composition and not based on the range of operating temperatures, as shown in Figure 1. A widely known classification distinguishes between low-, mid-, and high-temperature isomerization catalysts.…”

“…The first applies to highly chlorinated alumina catalysts; the second applies to sulfated zirconia catalysts; and the third applies to zeolite−platinum catalysts. 20 Upgrading of C 5 −C 6 alkanes may include the reactions of skeletal isomerization and alkylation of alkanes. The key steps of these reactions are activation of alkanes to form carbocations (carbenium ions), oligomerization, cracking, and coke formation.…”

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.

“…2). Isomerization catalysts based on sulfated metal oxides combines high activity and resistance to poisons and have ability to regeneration [1][2][3]. "One pass" isomerization technology is the simplest, has minimal capital and operation costs and provides the production of isomerate with 80-82 RON.…”

Abstract. An approach to simulation of hydrocarbons refining processes catalytic reactors. The kinetic and thermodynamic research of light naphtha isomerization process was conducted. The kinetic parameters of hydrocarbon feedstock chemical conversion on different types of platinumcontent catalysts was established. The estimation of efficiency of including different types of isomerization technologies in oil refinery flow diagram was performed.
