Definitions
- New hydrocarbon base oil for lubricants with very high viscosity index is a hydrocarbon base oil for lubricants with very high viscosity index.
- the invention relates to a new hydrocarbon base oil for high-end lubricants, obtained from hydrocarbon cuts from various sources. More specifically, the invention relates to an oil of this type, having a viscosity index VI, calculated according to standard NF T 60-136, greater than 130, for a kinematic viscosity measured at 100 ° C (Vk @ 100 ° C) , measured according to standard NF T 60-100, between 3.5 and 4.5 mm / s (or cSt).
- This new base oil finds a preferential application in the formulations of lubricants for engines, in particular in the automobile industry, as well as for industrial uses.
- Base oils are currently classified according to the API classification into five groups, according to characteristics defined in the following Table 1:
- viscosity index or VI of petroleum products is calculated from their kinematic viscosities at 40 ° C and 100 ° C, according to standard NF T 60-136.
- Such bases obtained from hydrocracking residues subjected to a dewaxing with solvent and forming part of group III according to the API classification described above, are currently produced, in particular by the Applicant, under the name NHC5 (“Neutral HydroCracked ”), with a Vk @ 100 ° C of 4.5 to 5 mm 2 / s (4.5 to 5 cSt).
- Patent application FR 2 194 767 A describes, in particular, a process for the preparation of a high VI lubricating oil, comprising a catalytic hydrocracking treatment of a fraction of mineral oil with high boiling point, a effluent fractionation, dewaxing of the boiling residue above 350 ° C. and catalytic hydroisomerization of the paraffin obtained.
- Another known route for obtaining high VI base oils consists in using highly paraffinic hydrocarbon charges, in particular composed of n-paraffins or waxes obtained by Fischer-Tropsch synthesis or slack wax.
- EP 0 323 092 A describes a process for producing high VI oil, comprising hydrotreatment, catalytic hydroisomerization and dewaxing stages
- WO 97/21788 A describes a process for the production of biodegradable lubricating base oil, comprising a step of hydroisomerization and catalytic hydrocracking of a fraction of boiling point above 370 ° C.
- the object of the present invention is therefore to obtain a new base oil for high-end lubricants, obtained from hydrocarbon cuts from various sources, having a high viscosity index and improved cold properties, in particular a pour point below -18 ° C, ensuring satisfactory rheological properties to the finished lubricating oils formulated from this base oil, in a wide range of temperatures (from -30 to + 100 ° C), thanks to a particular branching structure of the paraffinic molecules composing it.
- the base oil according to the invention is much better in performance than bases currently available on the market, derived from hydrocracked products and having undergone solvent dewaxing (oils of the NHC5 type), or dewaxing catalytic, and which belong to group III according to the API classification described above.
- it can also replace known synthetic bases such as poly- ⁇ -olefins (PAO), belonging to group IV, whose performances are well known for increasing the VI, but which have the major drawback of have a cost much higher than mineral bases.
- PAO poly- ⁇ -olefins
- the subject of the invention is a new hydrocarbon base oil for lubricants, having a viscosity index or VI greater than or equal to 130, mainly comprising long, isoparaffinic hydrocarbon chains, branched on several carbon atoms, characterized in that these chains comprise a number of carbon atoms greater than 25 and have a ratio of the number of substituents composed of at least two carbon atoms to the number of substituents of methyl type, greater than or equal to 0.9.
- said hydrocarbon chains have a ratio of the number of substituents composed of at least two carbon atoms, to the number of CH 2 of long chain, expressed in%, greater than or equal to 23%.
- the base oil in accordance with the invention has a ratio of the viscosity index cold (VIF) to the viscosity index (VI) (measured according to standard NF T 60-136) greater than or equal at 1.
- the base oil has a content of naphthenic molecules less than or equal to 10%.
- the base oil has a Noack volatility value of less than 13% by weight (calculated according to standard CEC-L-40-A 95), as well as a pour point (calculated according to standard NFT 60- 105) below -18 ° C.
- it has a Saybolt color value of + 30 (measured according to the ASTM D 156 method).
- the base oil has a cold viscosity index (VIF) greater than 125.
- the base oil has a dynamic CCS viscosity at -30 ° C of less than 1200 mPa.s (calculated according to standard ASTM D 5293), for a kinematic viscosity Vk at 100 ° C of 4 mm 2 / s.
- the base oil according to the invention has a viscosity index VI greater than 130 and less than or equal to 135, for a kinematic viscosity Vk at 100 ° C of between 3.5 and 4.5 mm 2 / s or cSt.
- this base oil has a viscosity index VI greater than 135 for a kinematic viscosity Vk at 100 ° C of between 4.5 and 5 mm 2 / s.
- a second object of the invention relates to the use of the base oil defined above, in the formulation of lubricants for engines, in particular for automobiles, with a view in particular to formulating a grade 0W30.
- a third subject of the invention relates to a process for the preparation of the base oil of the invention successively comprising the steps of hydrotreating, hydrodewaxing, fractionation and hydrofinishing of sections of residues resulting from hydrocracking.
- the new base oil exhibits advantageous properties when cold, characterized, on the one hand, by a pour point of less than - 18 ° C and, on the other hand , by a new so-called cold viscosity index (VIF) such that the oil has a cold viscosity index (VIF) / viscosity index (VI) ratio, greater than or equal to 1.
- the cold viscosity index VIF is calculated in using the usual formula for calculating the VI (according to standard NF T 60-136), which integrates the values of kinematic viscosity at 100 ° C and 40 ° C of the product to be measured, but by substituting the value of kinematic viscosity for 40 ° C, the kinematic viscosity value at -30 ° C. The latter is obtained by dividing the dynamic viscosity at - 30 ° C (which is measurable) by the density at - 30 ° C of the product, calculated from the density at 15 ° C, by temperature correction.
- base oil A base oil A
- competing products :
- - base oil B obtained from a very paraffinic filler, for example slack wax, hydrocracked and hydrodewaxed,
- All these oils have a kinematic viscosity Vk @ 100 ° C of between 4 and 5 mm 2 / s (4 and 5 cSt).
- Mass spectrometry made it possible to evaluate the content of naphthenic molecules in the various base oils: there are approximately 10% for oil A, as well as for oil B, against 30% for oil C, 40% for oil D and 60% for oil E.
- Paraffinic carbons the spectrum of these carbons is generally a spectrum of peaks in the region of saturated carbons (65-5 ppm). These peaks correspond to paraffinic carbons in particular environments. Most of these peaks are identified and attributed to known structures. In particular, we can distinguish: - the “long chain CH 2 ” peak characteristic of CH 2 units located at more than three carbon atoms from a chain end or a substitution; we note (see Table 2 below) that the height of this peak is significantly greater for base oil B than for other base oils, which indicates the presence of pieces of straight chains without substitution on average more long in this oil than in the others; oil D and oil A have lower values;
- the Applicant has implemented the following sequence of steps, from sections (of
- fillers can advantageously be used, in mixture with the previous fillers, for doping them, or in their replacement, in particular paraffins or synthetic waxes Fischer-Tropsch, waxes or slack waxes, and atmospheric or vacuum distillates.
- the lubricating base oil according to the invention by oligomerization of olefins, in particular of light alpha-olefins present in particular in the heavy petrol of visbreaking units or in l essence of FCC (cracker catalytic).
- This oligomerization is carried out in the presence of a catalyst of the phosphoric acid or aluminum chloride type, at temperatures of between approximately 190 ° C. and 340 ° C. and it leads to hydrocarbon products with very branched long chains.
- the base oils thus obtained having a VI greater than 130 and a VIF greater than 125, can replace synthetic lubricating bases of the PAO type, with an advantageous economic advantage, in formulations for oils for automobile engines and in particular in grades such as OW30, for which the requirements of cold properties are the most severe: kinematic viscosity Vk @ 100 ° C between 9.3 and 12.5 mm 2 / s and dynamic viscosity CCS at -30 ° C less than 3250 mPa.s.
- the Applicant has thus formulated a motor oil of grade 0W30 of composition, in% by weight: - base oil A: 80, 1
- This oil has the following characteristics: - kinematic viscosity Vk @ 100 ° C: 9.65 mm 2 / s
