Abstract (en)
[origin: WO2014177424A2] The invention provides a process for preparing a heavy base oil comprising the steps of: (a) providing a hydrocarbonaceous feedstock which contains at least 50% by weight of hydrocarbons boiling above 460 °C, nitrogen in amount in the range of from 800-2500 ppmw, and sulphur in an amount in the range of from 1.5-4.0 %wt ppmw; (b) hydrotreating the hydrocarbonaceous feedstock with a hydrotreating catalyst in the presence of a hydrogen- containing gas under hydrotreating conditions to obtain a hydrotreated product which contains nitrogen in an amount in the range of from 30-80 ppmw and sulphur in an amount in the range of from 200-450 ppmw; (c) removing at least 50% of the N¾ and ¾S which is present in the hydrotreated product as obtained in step (b); (d) catalytically dewaxing at least part of the hydrotreated product as obtained in step (c) with a dewaxing catalyst in the presence of a hydrogen- containing gas under catalytic dewaxing conditions to obtain a dewaxed product, which dewaxing catalyst comprises a Group VIII metal hydrogenation component, dealuminated aluminosilicate zeolite crystallites and a low acidity refractory oxide binder material which is essentially free of alumina; (e) hydrofinishing at least part of the dewaxed product as obtained in step (d) with a hydrofinishing catalyst in the presence of a hydrogen-containing gas under hydrofinishing conditions to obtain a heavy base oil; and (f) recovering the heavy base oil.
