Title (EN) PROCESS FOR THE SELECTIVE HYDRODESULFURIZATION OF OLEFINIC NAPHTHA STREAMS
(FR) PROCEDE D'HYDRODESULFURATION SELECTIVE DE FLUX DE NAPHTA
Abstract: front page image
(EN)A process for the hydrodesulfurization of cracked olefin streams is described, the process aiming at reducing the sulfur content while at the same time minimizing degree of said olefins. In order to dilute the added reaction hydrogen, the process makes use of non-reactive compounds such as N2, CH4, C2H6, C3H8, C4H10, CO2, group VIII noble gases as well as admixtures of same in any amount, in gas or vapor phase.
(FR)L'invention concerne un procédé d'hydrodésulfuration de flux d'oléfines craquées, ce procédé ayant pour but de réduire la teneur en soufre tout en minimisant en même temps le degré d'hydrogénation des oléfines. De façon à diluer l'hydrogène ajouté pendant la réaction, le procédé utilise des composés non réactifs tels que N2, CH4, C2H6, C3H8, C4H10, CO2, des gaz rares du groupe VIII ainsi que des mélanges de ces composés en une quelconque quantité, en phase gazeuse ou en phase vapeur.
