Abstract
(EN) A distillate super/subcritical fluid enhanced hydrogenation method, comprising: preheating a mixture of a distillate raw material, a solvent and hydrogen, then introducing the mixture into a first-stage fixed bed reactor, carrying out first-stage catalytic hydrogenation in a supercritical or subcritical fluid state, separating a reaction effluent, collecting a hydrogenated oil product therein and obtaining a hydrogen-containing gas and a solvent-containing light fraction; and returning the solvent-containing light fraction to the first-stage fixed bed reactor for recycling. The method improves the solubility and diffusion mass transfer performance of hydrogen in a distillate hydrogenation reaction system, and improves the hydrogenation reaction efficiency of the distillate.
(FR) L'invention concerne un procédé d'hydrogénation de distillat amélioré par fluide supercritique/sous-critique, consistant à : préchauffer un mélange d'une matière première de distillat, un solvant et de l'hydrogène, puis introduire le mélange dans un réacteur à lit fixe de premier étage, effectuer une hydrogénation catalytique de premier étage dans un état fluide supercritique ou sous-critique, séparer un effluent de réaction, collecter un produit huileux hydrogéné en son sein et obtenir un gaz contenant de l'hydrogène et une fraction légère contenant un solvant ; et renvoyer la fraction légère contenant un solvant au réacteur à lit fixe de premier étage pour le recyclage. Le procédé améliore la solubilité et la performance de transfert de masse par diffusion de l'hydrogène dans un système de réaction d'hydrogénation de distillat et améliore l'efficacité de la réaction d'hydrogénation du distillat.
(ZH) 一种馏分油超/亚临界流体强化加氢方法,包括:将馏分油原料、溶剂和氢气的混合物料预热后通入第一段固定床反应器中,在超临界或亚临界流体状态下进行第一段催化加氢,对反应流出物进行分离,收集其中的加氢油品并获得含氢气体以及含溶剂轻馏分;将含溶剂轻馏分返回第一段固定床反应器中循环使用。该方法改善了氢气在馏分油加氢反应体系中的溶解性能和扩散传质性能,提高馏分油的加氢反应效率。
