Abstract:
1. Isomerization device for a hydrocarbonic charge that contains a substantial quantity of paraffin base hydrocarbons with 5 or 6 carbon atoms and whose benzene content is greater than or equal to 2% by weight, said device contains at least one reactor ( 5 ) charged with a fixed-bed catalyst ( 6 ), an incoming line ( 33 ) to the reactor ( 5 ) for the reaction mixture consisting of the charge mixed with a gas that is rich in hydrogen, at least one heating system ( 3 , 4 ) of said reaction mixture upstream from the factor ( 5 ), and an evacuation line ( 10 ) from the reactor ( 5 ) for the charge enriched with isoparaffins, said device being wherein, in the upstream section of the reaction zone, emerges at least one means ( 11 ) of introduction of an adjunctive fluid, that is in a gaseous phase at 40° C., under atmospheric pressure (1.0134.10 5 Pa).
