Title
(FR) SUPERCRITICAL/SUBCRITICAL FLUID ENHANCED HYDROGENATION METHOD OF DISTILLATE
Abstract
(FR) Procédé d’hydrogénation de distillat améliorée par fluide supercritique/subcritique. La présente invention propose un procédé d’hydrogénation de distillat améliorée par fluide supercritique/subcritique, incluant au moins : le préchauffage d’un mélange d’une charge de distillat, d’un solvant et d’hydrogène et leur introduction dans un réacteur à lit fixe de premier étage, la réalisation d’une hydrogénation catalytique de premier étage dans un état de fluide supercritique ou subcritique pour obtenir un effluent de réaction d’hydrogénation catalytique; la réalisation d’une séparation sur l’effluent de réaction d’hydrogénation catalytique, pour collecter un produit d’huile hydrogénée et obtenir un gaz contenant de l’hydrogène et un distillat léger contenant un solvant ; le renvoi du distillat léger contenant un solvant vers une matière mélangée du réacteur à lit fixe de premier étage pour remplacer le solvant pour recyclage. Dans le procédé de la présente invention, en réalisant la réaction par hydrogénation catalytique de distillat dans un état de fluide supercritique/subcritique, une performance de solubilité et une performance de diffusion et de transfert de masse d’hydrogène dans un système de réaction d’hydrogénation de distillat sont fortement améliorées, et les rendements d’hydrodésulfuration, d’hydrodénitrification, de saturation par hydrogénation oléfinique et aromatique, et d’hydrocraquage, etc., de distillat sont fortement améliorés de sorte à réaliser une conversion par hydrogénation économique et rentable de la charge de distillat.
