Abstract
Procédé pour traiter les huiles obtenues en sous-produits dans les craquages thermiques d'hydrocarbures pétroliers, en vue d'en éliminer les composants insaturés. On sépare d'abord de ces huiles un distillat bouillant entre 75 et 198 degrés C et contenant de 5 à 100 moles % d'oléfines aromatiques, par rapport aux hydrocarbures aromatiques totaux, à l'exclusion des oléfines aromatiques, qu'on traite en phase liquide sur un catalyseur acide à une température de 0 à 200 degrés C en une durée de 6 mn à 5 h, avec une teneur maximale de 5 % en poids d'oléfines aromatiques dans le mélange de réaction. Le traitement selon l'invention donne un distillat qui ne contient plus de composants insaturés parce que les xylènes et le styrène contenus dans la fraction de départ se sont condensés avec formation de composés aromatiques di- et tricycliques non condensés, donnant une huile lourde possédant des applications industrielles variées.
