Title (EN) PROCESS AND CATALYSTS FOR THE OPENING OF NAPHTHENE RINGS
(FR) PROCEDE ET CATALYSEURS DESTINES A L'OUVERTURE DE CYCLES DE NAPHTALENE
Abstract: front page image
(EN)A process is described for the upgrading of distil­ lates having a boiling point ranging from 100 to 450°C, which comprises the opening of the ring of the naphthene compounds contained in these distillates to obtain paraf­finic compounds, rich in branched paraffins, having for the most part the same number of carbon atoms as the starting naphthene. The process is carried out in the presence of a bifunctional catalytic system comprising one or more metals selected from Pt, Pd, Ir, Ru, Rh and Re, and a silico­aluminate of an acidic nature, selected from a micro­mesoporous silico-alumina and a zeolite belonging to the MTW group.
(FR)L'invention concerne un procédé permettant de valoriser des distillats possédant un point d'ébullition compris entre 100 et 450 °C et consistant à ouvrir le cycle des composés de naphtalène renfermés dans ces distillats, aux fins d'obtention de composés paraffiniques, riches en paraffines ramifiées, la majorité possédant le même nombre d'atomes de carbone comme naphtalène de départ. Le procédé est effectué en présence d'un système catalytique bifonctionnel comprenant un ou plusieurs métaux sélectionnés dans Pt, Pd, Ir, Ru, Rh et Re et un silico-aluminate d'une nature acide, sélectionné parmi une silico-alumine micro-mésoporeuse et un zéolite appartenant au groupe MTW.
