    Abstract: A process for separating multibranched paraffins comprised in a hydrocarbon feed comprising hydrocarbons containing 5 to 8 carbon atoms per molecule comprises a separation unit functioning by adsorption and contains at least one zeolitic adsorbent with a mixed structure with principal channels with openings defined by a ring containing 10 oxygen atoms and secondary channels with openings defined by a ring of at least 12 oxygen atoms, the secondary channels only being accessible to the feed to be separated via the principal channels. Particular zeolitic adsorbents of the invention are zeolites with structure types EUO, NES and MWW. NU-85 and NU-86 zeolites are also particularly suitable for carrying out the process of the invention.

    Abstract: The invention relates to a method of isomerising a charge comprising hydrocarbons containing between 5 and 8 carbon atoms per molecule. According to the invention, said charge is separated into at least two fractions: fraction A mostly comprising hydrocarbons containing 5 or 6 carbon atoms and fraction B mostly comprising hydrocarbons containing 7 or 8 carbon atoms. Subsequently, said fractions A and B are treated separately under specific conditions in different isomerisation reaction zones.

    Abstract: The liquid hydrocarbon stream including COS is introduced via line 1 into membrane contactor CM to be placed in contact, through membrane M, with the aqueous alkanolamine solution arriving via line 3. The COS contained in the hydrocarbon stream is absorbed by the aqueous alkanolamine solution. The liquid hydrocarbons from which the COS has been removed are evacuated from CM via line 2. The aqueous solution containing COS is sent via line 4 to zone R to be regenerated. The compounds released during regeneration, particularly COS and COS-derived products, are evacuated from zone R via line 5. The regenerated aqueous alkanolamine solution is recycled via line 3 into membrane contactor CM.
