Abstract
A method for the isomerization of a hydrocarbonic charge containing a substantial quantity of paraffin base hydrocarbons with 5 or 6 carbon atoms and a benzene content that is greater than or equal to 2% by weight, in which the charge to be treated passes, in the presence of hydrogen, at a total pressure greater than or equal to 10.105 Pa (10 bars) and at an average temperature ranging between 100 and 200° C., through at least one reactor (5) containing a catalyst. An adjunctive fluid is introduced in the upstream section of the reaction zone; a fluid that at 40° C. and under atmospheric pressure (1.0134.105 Pa), is in a gaseous phase and has a density that is less than or equal to that of the normal-pentane taken into account under the same conditions.
