Title (EN) PROCESS FOR PREPARING BASESTOCKS HAVING HIGH VI USING OXYGENATED DEWAXING CATALYST
(FR) PROCEDE DE PREPARATION D'HUILES DE BASE AYANT UN INDICE DE VISCOSITE ELEVE FAISANT APPEL A UN CATALYSEUR DE DEPARAFFINAGE OXYGENE
Abstract: front page image
(EN)A process for preparing high VI lubricating oil basestocks comprising hydrotreating, hydrodewaxing and optionally hydrofinishing. The hydrotreated feedstock is hydrodewaxed using a dewaxing catalyst that has been selectively activated by oxygenate treatment. The hydrodewaxed product may then be hydrofinished.
(FR)L'invention concerne un procédé de préparation d'huiles de base lubrifiantes à indice de viscosité élevé comprenant l'hydrotraitement, l'hydrodéparaffinage et éventuellement l'hydrofinition. La charge d'alimentation hydrotraitée est hydrodéparaffinée au moyen d'un catalyseur de déparaffinage qui a été activé de manière sélective par un traitement au composé oxygéné. Le produit hydrodéparaffiné peut alors être hydrofini.
