    • Process to prepare simultaneously two or more base oil grades and middle distillates from a mineral crude derived feed, in particular a de-asphalted oil or a vacuum distillate feed or their mixtures, by performing the following steps: (a) hydrocracking the mineral crude derived feed, thereby obtaining an effluent; (b) distillation of the effluent as obtained in step (a) into one or more middle distillates and a full range residue boiling substantially above 340 ‹C, (c) catalytically dewaxing the full range residue by contacting the residue with a dewaxing catalyst comprising a zeolite of the MTW type and a Group VIII metal, thereby obtaining a dewaxed oil; (d) isolating by means of distillation two or more base oil grades from the dewaxed oil obtained in step (c); and (e) isolating a dewaxed gas oil from the dewaxed-oil obtained in step (c); wherein the dewaxed oil as obtained in step (c) comprises between 10 and 40 wt% of a dewaxed heavy gas oil boiling for more than 70 wt% between 370 and 400 ‹C. ® KIPO & WIPO 2007
    • 通过进行以下步骤同时制备来自矿物原油衍生的原料,特别是脱沥青油或真空馏分进料或其混合物的两种或更多种基础油级和中间馏分的方法:(a)加氢裂化衍生的矿物粗品 进料,从而获得流出物; (b)将步骤(a)中获得的流出物蒸馏成一个或多个中间馏分和大致高于340℃沸点的全范围残余物,(c)通过使残余物与脱蜡催化剂进行催化脱蜡,所述脱蜡催化剂包含 MTW型沸石和VIII族金属,得到脱蜡油; (d)通过蒸馏从步骤(c)中获得的脱蜡油中分离出两种或更多种基础油级; 和(e)从步骤(c)中获得的脱蜡油中分离脱蜡瓦斯油; 其中在步骤(c)中获得的脱蜡油包含10-40重量%的在370和400℃之间沸腾超过70重量%的脱蜡重质瓦斯油。 ®KIPO&WIPO 2007
