“…Dr. Haensel proposed the use of small platinum metal particles on the alumina surface acid base to conduct chemical reactions in order to optimize and gasoline octane number improvement after much research in 1947 [14]. Subsequently, in 1949, Dr. Hansel's process has become commercial on industrial scale by UOP Company to produce gasoline with a high octane number from Naphtha and this process of UOP Company is known as plat forming process in the world [15]. The first plat forming unit of Naphtha was built in 1949 at the old Dutch oil refinery, Michigan, United States and in this way, the catalyst conversion reforming process was functionally and industrially introduced and developed during 1947 to 1949 [16][17][18][19].…”

“…These catalysts have good resistance to sulphur compounds but it is difficult to restore them and they do not have a good thermal stability, especially in the temperature range of 80 to 190 °C [26,27]. MoO3 restoration with hydrogen gas at 350 °C improves the activity and selectivity of the catalyst for Gasoline process.…”

The aim of this study is to investigate naphtha Gasoline unit catalysts. In twofactor catalysts, platinum or palladium was used as the active metal on the base alumina chloride, zirconia, and zeolite. Considering the fact that refining and gasoline processes are expanding and refineries in Iran are required to produce cleaner fuels that meet environmental standards, investigating different kinds of light naphtha gasoline unit catalysts can greatly help to promote production of clean fuel and make production process more efficient. Light naphtha gasoline is normally conversion of normal pentane and normal hexane compounds to its branched compounds. Also Light naphtha its derivatives and it is done by chlorinated ammonia or zeolite catalysts in one or some fixed bed reactors. Activity of two-factor catalysts strongly depends on acidic and metal sites. For example, in catalyst Pt./HY, which is a kind of zeolite catalyst for Gasoline Units, the optimal ratio of strong acidic sites to metal sites in n-heptane Gasoline is determined to be less than 6. In this work, various kinds of catalysts used in isomerization unit were identified and considered.

Nowadays, computational tools for analyzing and collecting data in the operation of petroleum units are essential. One of the methods is the classification or regression is to step in the overall process of knowledge extraction. In this study, one of specific type of decision called the conditional contract arrangement, is used to extract the relevant knowledge in Catalytic Reforming Units (CRU) for 4 factors: Density, PH, total iron ions in vessels (S.FE) and H2S. All of these factors are related to corrosion in CRU and this paper aims to optimize some conditions to eliminate it. In this regard, using ammonium water with a specific range and PH can be helpful. According to the obtained results the best range of density (in Feed) is less than 0.515 kg/m 3 , PH (water in vessels) is more than 6.7, S.FE is less than 1.5 ppm and H2S in recycle gas is less than 700 ppm. The outcomes also show how this approach can be used to gain insight into some refineries and how to deliver results in a comprehensible and user-friendly way.
