بهينه سازي پارامترها و شرايط عملياتي در فرايند كاتاليستي ايزومري شدن برش نفتاي سبك LSRG به منظور ارتقاي ارزش افزوده

The octane number of most light naphtha cuts can be increased by hydro-isomerization process. This process can be considerably beneficial, when accompanied by processes whose goals are reduction of sulfur and benzene contents of the gasoline. Alanv of such processes have undesirable effects on the octane number. In addition the unreliability ofA TBE rules in the future, dictates the use of isomerization processes, which produce non-aromatic and sulfur free compositions without any expected environmental hazard. One of the most important methods, which is used .for the production of iso-alkane, is naphtha isomerization. In this catalytic process, under suitable temperature and pressure conditions, paraffin chain is re-arranged to multi branched isomers. In literatures special attention has been paid to the isomerization of one or two components in the reaction, while this paper analyses an isomerization mechanism on a specific cut of distillation column, and illustrates the influence of other components and parameters on the base components finally. The most suitable operational conditions and parameter values, which influence the quality and efficiency of the process, have been estimated.
