Title (EN) BLOCKED OPERATION FOR GROUP II AND GROUP III LUBRICANT PRODUCTION
(FR) OPÉRATION BLOQUÉE POUR LA PRODUCTION DE LUBRIFIANTS DE GROUPE II ET DE GROUPE III
Abstract:
(EN) Systems and methods are provided for block processing of a feedstock to produce multiple viscosity grades of lubricant base stocks with substantially different viscosity index values. The systems and methods can involve the use of a sweet stage hydrocracking catalyst that can maintain good aromatic saturation activity under conditions that produce substantially different levels of viscosity index uplift. Optionally, the reactor including the sweet stage hydrocracking catalyst can include additional aromatic saturation catalyst. The systems and methods can further involve using a combination of aromatic saturation catalyst and dewaxing catalyst in a second sweet stage reactor, so that additional aromatic saturation activity is available for saturation of aromatics for products that undergo lower amounts of conversion in the sweet hydrocracking stage. The systems and methods can also allow for increased control over the relative temperatures of reactors within a reaction system.
(FR) L'invention concerne des systèmes et des procédés pour le traitement par blocs d'une charge d'alimentation pour produire de multiples grades de viscosité d'huiles de base lubrifiantes ayant des valeurs d'indice de viscosité sensiblement différentes. Les systèmes et les procédés peuvent impliquer l'utilisation d'un catalyseur d'hydrocraquage en phase douce qui peut maintenir une bonne activité de saturation aromatique dans des conditions qui produisent des niveaux sensiblement différents d'élévation d'indice de viscosité. Le réacteur contenant le catalyseur d'hydrocraquage en phase douce peut éventuellement contenir un catalyseur de saturation aromatique supplémentaire. Les systèmes et les procédés peuvent en outre comprendre l'utilisation d'une combinaison de catalyseur de saturation aromatique et de catalyseur de déparaffinage dans un second réacteur en phase douce, de façon qu'une activité de saturation aromatique supplémentaire soit disponible pour la saturation des composés aromatiques des produits qui subissent des quantités inférieures de conversion dans l'étape d'hydrocraquage doux. Les systèmes et les procédés peuvent également permettre un contrôle accru des températures relatives des réacteurs au sein d'un système de réaction.
