Definitions
- This invention relates to lubricant base oils and lubricant compositions and to methods for making them.
- Lubricant compositions generally comprise a base oil and one or more additives.
- base stocks which are used for base oils are defined as belonging to one of five Groups as set out in Table I below.
- Table I Group Saturated hydrocarbon content (wt%) Sulphur content (wt%) Viscosity Index I ⁇ 90 and/or > 0.03 and ⁇ 80 and ⁇ 120 II ⁇ 90 and ⁇ 0.03 and ⁇ 80 and ⁇ 120 III ⁇ 90 and ⁇ 0.03 and ⁇ 120 IV polyalpha olefins V all base stocks not in Groups I, II, III or IV
- Group I base stocks are generally preferred to Group II base stocks for the manufacture of lubricant compositions for marine 2-stroke and 4-stroke engines, particularly for engines operating on heavy fuel oil.
- Group II base stocks are becoming increasingly more readily available because older manufacturing capacity for Group I basestock is being closed and new manufacturing capacity tends to manufacture Group II base stock.
- Group II base stocks may have some performance disadvantages compared to Group I base stocks when used in some lubricant compositions, for example in marine lubricants. These disadvantages may include poorer dispersancy, poorer seal swell performance, poorer solubility of additives, lower compatibility with fuel oil in marine engine applications (which can lead to deposit formation, for example in cool parts of the engine) and/or in some aspects, poorer oxidative stability.
- Hydroprocessed base stocks may have advantages and disadvantages ( Deckman, D.E. et al., Hart's Lubricants World, July 1997, pages 46 - 50 ) when used in industrial lubricant applications ( Deckman D. E. et al., Hart's Lubricants World, Sept 1997, pages 20-26 ) and in commercial, personal vehicle and marine engine oils ( Deckman D. E. et al., Hart's Lubricants World, Sept 1997, pages 27 - 28 ).
- Base stocks which are made by hydroprocessing have lower aromatics content and lower sulphur content than Group I base stocks.
- GB2083494 , US4777307 , EP0709447 , US2003/100453 , GB1237291 , GB1237292 and DE2656652 relate to hydroprocessed oils. They disclose the addition of either aromatic extracts, aromatic fractions, multiring aromatic compounds or bright stock to these for improving their oxidation stability.
- EP0839891 discloses aromatic process oils for rubber extenders having polycyclic aromatics content less than 3 %.
- Base stocks derived from Fischer-Tropsch synthesised, waxy, paraffinic hydrocarbon materials also have a low aromatics content and so may also exhibit at least some of the poorer performance of Group II and Group III base stocks compared to Group I base stocks.
- WO 00/14187 and WO 2005/066314 relate to lubricant compositions comprising Fischer Tropsch derived base stock.
- a liquid marine lubricant base oil composition which method comprises blending: (i) a base stock comprising at least 95 % by weight saturated hydrocarbons, the base stockcomprising a hydroprocessed base stock and/or a base stock derived from Fischer-Tropsch synthesised, waxy, paraffinic hydrocarbon material, with (ii) 0.2 to 30 % by weight of an aromatic extract which has an aromatics content of 60 to 85% by weight as measured by ASTM D 2007 and a dimethyl sulphoxide extractable polycyclic aromatics content of less than 3 weight % as measured by IP 346, to make a liquid lubricant base oil composition.
- the present invention solves the problem defined above by the use of 0.2 to 30 % by weight of an aromatic extract which has a dimethyl sulphoxide extractable polycyclic aromatics content of less than 3 weight % in a liquid lubricant base oil composition which base oil comprises a base stock comprising at least 95 % by weight saturated hydrocarbons.
- This provides a lubricant base oil which overcomes or at least mitigates, at least some of the deficiencies which may be associated with such base stocks.
- the lubricant base oil composition prepared according to the method of the present invention comprises 0.2 to 30 % by weight of an aromatic extract.
- the lubricant base oil composition comprises 0.2 to 18 % or 1.0 to 30 % by weight of the aromatic extract. More preferably, the lubricant base oil composition comprises 1.0 to 18 % by weight aromatic extract.
- the base stock comprising at least 95 % by weight saturated hydrocarbons comprises a hydroprocessed base stock and/or a base stock derived from Fischer-Tropsch synthesised, waxy, paraffinic hydrocarbon material.
- the lubricant base oil composition prepared according to the method of the present invention overcomes or at least mitigates, at least one of the deficiencies which may be associated with such base stocks, for example those deficiencies selected from the group consisting of poor dispersancy (for example, of soot and/or deposits), poor seal swell performance, poor solubility of additives and low compatibility with fuel oil in marine engine applications (which can lead to deposit formation, for example in cool parts of the engine), and also in some aspects, poor oxidative stability.
