Abstract:
Method for the isomerization of a hydrocarbonic charge containing 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 10Ã—105 Pa (10 bars) and at an average temperature ranging between 100 and 200Â° C., through at least one reactor (5) containing an isomerization catalyst for the treatment of paraffin base hydrocarbons, wherein an adjunctive fluid is introduced in the upstream section of the reaction zone at a flow rate of from 5 to 150 Nm3 per m3 of charge; the adjunctive fluid consisting essentially of hydrocarbons that contain from one to four carbon atoms.
