The hydrocracking can be carried out at 650-875‹F. with a hydrogen partial pressure of 500-10,000 p.s.i. using a catalyst comprising at least one oxide or sulphide of Ni, W, Co or Mo on an alumina carrier. The catalyst can be used in two or more beds so that the feed can be fractionated and fed so that the heavier fractions can undergo more severe cracking.

Lubricating oils with a viscosity index of at least 125 are prepared from petroleum feedstocks with a viscosity index of at least 90 by solvent extracting the feedstock to give a raffinate with a content of carbon in the form of aromatic rings of less than 5%, treating the raffinate so obtained in the presence of hydrogen and a hydrogenation catalyst at 200-800 DEG F. and 1000-2000 p.s.i.g., and recovering a product having an increased viscosity index of at least 125. This product may then be fractionated to remove lower-boiling material and dewaxed. Finally clay treatment of hydrofinishing may be carried out. The hydrocatalytic treatment may be effected in a single stage in the presence of a sulphur insensitive catalyst such as tungsten-nickel sulphide, or in two stages, first with a sulphur-insensitive catalyst to effect desulphurization, and then with a sulphur-sensitive catalyst. The finished oil may have oxidation inhibitors added, for example, antimony diamyl dithiocarbamate blended ...

Naphthenic type lubricating oils are obtained by subjecting a mixed base lubricating oil distillate fraction to a solvent extraction and dewaxing treatment, the solvent extraction including the steps of extracting with an aromatic-selective solvent, for example, phenol, furfural, liquid SO2, nitrobenzene, and nitroparaffins, in a first stage to obtain a first extract phase, which extract phase is then separated into a second extract phase and a second raffinate phase, from which raffinate phase most of the paraffinic and aromatic compounds have been excluded, and hydrogenating the dewaxed second raffinate in the presence of a catalyst. The dewaxing step may either precede or preferably follow the solvent extraction. The separation of the first extract phase may be effected by at least one of the steps of cooling and injection of anti-solvent, for example water, if desired with concomitant extraction with an aromatic-selective solvent. The dewaxing may be effected by means of a solvent, ...

Methods are provided for processing deasphalted gas oils derived from thermally cracked resid fractions to form Group I, Group II, and/or Group III lubricant base oils. The yield of lubricant base oils (optionally also referred to as base stocks) can be increased by thermally cracking a resid fraction at an intermediate level of single pass severity relative to conventional methods. By performing thermal cracking to a partial level of conversion, compounds within a resid fraction that are beneficial for increasing both the viscosity and the viscosity index of a lubricant base oil can be retained, thus allowing for an improved yield of higher viscosity lubricant base oils from a thermally cracked resid fraction.

Performing hydrofinishing after fractionation can allow the high hydrogen pressure for hydrofinishing to be used on one or more lubricant base oil fractions that are desirable for high pressure hydrofinishing. This can allow for improved aromatic saturation of a lubricant base oil product while reducing or minimizing the hydrogen consumption. The high pressure hydrofinishing can be performed at a hydrogen partial pressure of at least about 2500 psig (˜17.2 Mpa), or at least about 2600 psig (˜18.0 Mpa), or at least about 3000 psig (˜20.6 MPa). The high pressure hydrofinishing can allow for formation of a lubricant base oil product with a reduced or minimized aromatics content, a reduced or minimized 3-ring aromatics content, or a combination thereof.
