Abstract
A procedure for the alkylation of isobutane by olefinic hydrocarbons, in which a first hydrocarbon charge ( ) rich in isobutane is put in contact with a second hydrocarbon charge rich in light olefins ( ), under conditions that will provoke the alkylation of the isobutane by the light olefins, the effluents that emanate from the reaction area in a fractionation column ( ) are treated in order to extract therefrom at least a first cut rich in alkylate ( ), a second cut rich in normal butane ( ) and a third cut rich in isobutane ( ), said third cut ( ) is then recycled at the entry of the alkylation reaction area. The second cut ( ) rich in normal butane is purified ( ) so as to lower its content in compounds with 5 or more carbon atoms to a value that is less than or equal to 5% by weight, the cut thus purified ( ) is treated in an isomerization reactor ( ) of normal butane to isobutane, this cut is then recycled ( ) at the entry of the alkylation effluents fractionation column ( ).
