Title : The production of the gasoline with high quality with high octane number by the use of the bifunctional catalyst pt / re in the catalytic reforming process.


The original function of the process of platforming is to  develop heavy naphtha (HSRN), coming from the  atmospheric unit of distillation with a weak octane number (NO = 44),  to obtain a mixture of fuels â number octane raised by catalytically  supporting specific groups of chemical reactions.
The installation is divided into two sections: Section hydrobon. Section platforming.
The rafinat coming from the bottom of column 12C2 to feed  the section platforming, is divided into two parts whose flows are  controlled and mixed  with gas rich in hydrogen. Bottom of the column, we obtain stabilized reformat which  is aspired by there pump to ensure the heating of the column whereas a part  is sent towards storage after being cooled by the air cooler and the  condenser. In catalytic catalyst of reforming, there is voluntarily  associated a hydrogenating function - dehydrogenating, brought by  platinum deposited, with an acid function brought by the alumina  support (Al 2 0 3 .  The mechanism  of action of this bifunctionnal catalyst depends on the severity of the  operation, of the quality of the load and the type of catalyst. The catalyst used in the catalytic process of reforming is a  very elaborate bifunctional catalyst whose performances are constantly  improved thanks to the experimental research supported on an  increasingly large comprehension of the phenomena.The American company Universel 0i1 petroleum  (UOP) marketed several series of bimetallic catalysts such as  R16, R20, R30 and R62 consisted  Platinum / Rhenium on an acid support consisted the alumina added  with a halogenous compound (chlorine) .
