The present invention relates to a process for denitrogenating a distillate stream by contacting an organic nitrogen-containing petroleum distillate feed in the presence of an aqueous base selected from Group IA and IIA hydroxides and ammonium hydroxide and mixtures thereof, a phase transfer agent at a temperature and pressure effective to produce a treated petroleum feed having a decreased organic nitrogen content.
La présente invention concerne un procédé de dénitrogénation d'un courant de distillat, consistant à mettre un distillat de pétrole contenant de l'azote organique en présence d'une base aqueuse sélectionnée parmi les hydroxydes des groupes IA et IIA et de l'hydroxyde d'ammonium et des mélanges de ces produits, et un agent de transfère de phase à une température et à une pression permettant de produire un pétrole traité appauvri en azote organique.
