As mentioned, another important characteristic of gasoline produced in addition to octane number is the amount of benzene in it. The maximum permitted benzene level is ۱% vol. in accordance with the European standard of ۲۰۰۵ in gasoline. Of course, for ۲۰۱۱, the United States has lowered benzene levels to ۰.۶۲%. Therefore, in optimizing the gasoline product, the parameters affecting the reduction of benzene production should be considered. In this research, we tried to study the changes in the distillation curve of the refined heavy naphtha catalytic converter unit, the results of the octane number and the benzene volume percentage contained in the final gasoline product. In order to carry out this study, changes in the Reboiler thermal bar of the naphtha hydrogen purifier separator tower should be made in response to the low temperature variations of the tower and, consequently, the value of the product distillation curve at the bottom of the tower, which is essentially the feed of the catalytic converter unit. This study was carried out under nominal capacity of ۱۵۰ ton/hr, heavy catalytic converter and flow of ۲۲ ton per circulating gas with ۹۲ percent purity of hydrogen and ۸۰۰ kg/h of catalyst and ۵۲۵ °C reactors input.
