Process for producing paraffinic hydrocarbons, the process comprising the following steps: (a) contacting hydrogen and a feedstock comprising triglycerides, diglycerides, monoglycerides and/or fatty acids with a hydrogenation catalyst under hydrodeoxygenation conditions; and (b) contacting the whole effluent of step (a) with a hydroprocessing catalyst comprising sulphided Ni and sulphided W or Mo as hydrogenation components on a carrier comprising amorphous silica-alumina and/or a zeolitic compound under hydro-isomerization conditions.

Process for producing paraffinic hydrocarbons

Process to prepare a water-white lubricating base oil having a saturates content of more than 90 wt %, a sulphur content of less than 0.03 wt % and a viscosity index of between 80-120 by subjecting a non-water-white hydrocarbon feed having a lower saturates content than the desired saturates content to a hydrogenation step, the hydrogenation step comprising contacting the feed with hydrogen in the presence of a hydrogenation catalyst, wherein the contacting is performed in two steps: (a) contacting the hydrocarbon feed with hydrogen in the presence of a hydrogenation catalyst at a temperature of above 300&#xb0; C. and at a WSHV of between 0.3 and 2 kg of oil per litre of catalyst per hour, and (b) contacting the intermediate product obtained in step (a) with hydrogen in the presence of a hydrogenation catalyst at a temperature of below 280&#xb0; C.

Process to prepare water-white lubricant base oil

Process to prepare a base oil having a viscosity index of between 80 and 140 starting from a distillate or a de-asphalted oil by (a) contacting the feedstock in the presence of hydrogen with a sulphided hydrodesulphurization catalyst comprising nickel and tungsten on an acid amorphous silica-alumina carrier and (b) performing a pour point reducing step on the effluent of step (a) to obtain the base oil.

Process to prepare a lubricant having a dynamic viscosity at &#x2212;35&#xb0; C. of below 5000 cP by performing the following steps: a) contacting a feed containing more than 50 wt % wax in the presence of hydrogen with a catalyst comprising a Group VIII metal component supported on a refractory oxide carrier, and b) contacting the effluent of step (a) with a catalyst composition comprising a noble Group VIII metal, a binder and zeolite crystallites of the MTW type to obtain a product having a lower pour point than the effluent of step (b) and having a viscosity index greater than 120, and (c) adding a pour point depressant additive to the base oil as obtained in step (b).

Process for the preparation of a lubricant

Process to prepare a lubricating base oil starting from a lubricating base oil which is obtained by first removing part of the aromatic compounds from a petroleum fraction boiling in the lubricating oil range by solvent extraction and subsequently dewaxing the solvent extracted product, wherein the following steps are performed, (a) contacting the lubricating base oil with a suitable sulphided hydrotreating catalyst in a first hydrotreating step; (b) separating the effluent of step (a) into a gaseous fraction and a liquid fraction; (c) contacting the liquid fraction of step (b) with a catalyst comprising a noble metal component supported on an amorphous refractory oxide carrier in the presence of hydrogen in a second hydrotreating step; and (d) recovering the lubricating base oil.
