In chemistry, isomerization or isomerisation is the process in which a molecule, polyatomic ion or molecular fragment is transformed into an isomer with a different chemical structure. [1] Enolization is an example of isomerization, as is tautomerization .

2018年9月1日 · Isomerization reactor is the heart of isomerization process (Fig. 1) in petroleum refineries to enhance research octane number (RON) of gasoline products. Isomerization is the rearrangement of straight-chain hydrocarbons components converting to branched hydrocarbons components with higher octane number ( Yasakova et al., 2010 ).

Isomerization, the chemical process by which a compound is transformed into any of its isomeric forms, i.e., forms with the same chemical composition but with different structure or configuration and, hence, generally with different physical and chemical properties.

2024年4月5日 · Numerical simulations of C 8 aromatics isomerization in radial reactors are important for understanding fluid flow, heat and mass transfer, complex reactions, and operational optimization. To investigate these aspects, we develop a three-dimensional porous media model integrated with modified reaction kinetics.

Isomerization is a degradation process in which a drug degrades to form a product with an identical chemical formula (i.e., isomers). Isomers have the same chemical composition but a different configuration or structure and possess different physicochemical properties.

The isomerization is the process whereby a molecule transform in another one, where the new compound had the same atoms than the first, however, they are organized in a different way [4].

2023年6月12日 · This study investigated mathematical modeling and optimization of the xylene isomerization reaction in a commercial adiabatic reactor. The proposed model, consisting of a set of algebraic and ordinary differential equations, is based on a heterogeneous one-dimensional steady-state formulation.

2023年12月11日 · Jarullah et al. introduced a new naphtha isomerization process, called AJAM, where the isomerization reactor model was validated using data from Baiji North Refinery (BNR). In their study, it is found that adding a de-isopentanizer “DIP” has a positive effect on the research octane number (RON), isomerate properties, and operation cost.

2019年9月30日 · In this article we present a multi-response optimization strategy for an industrial naphtha continuous isomerization process that aims to maximize RON, PIN and yield.
