Catalytic Reforming

The catalytic reforming one is procécé used in Raffinage to convert the naphtenic molecules into aromatic molecules having a Number octane as a basis high being used in manufacture of the Carburant S Automobile.

In this process, one uses a Catalyseur which makes it possible to initiate the chemical reactions. Starting from a heavy naphtha removed from Sulfur, one makes pass the product through a series of 3 engines which transform the naphtenic products into aromatic products by partially removing them from the Hydrogène. On the outlet side of the engines, after passage in the fractionator one a:

of the Hydrogen,
of the Fuel gas (Methane and ethane),
of propane,
of butane,
of the reformat.

The reaction is done under pressure and with high Température of about 500-550 °C.

hydrogen will be used in the hydro-treating and the Hydrodésulfuration,
fuel gas is directed towards the combustible network of Gaz,
propane and butane is directed towards the storage of these products,
finally the reformat will be mixed with light naphtha and butane in well defined proportions to give ordinary fuel and super fuel, or by a mode of fractionation of the reformat one aromatic obtien LMBO hydrocarbons BTX very research in petrochemical industry.

In a complex refinery, one adds also isomérats and ethanol to make fuel without Plomb.
