In some embodiments, bio-derived fatty acid moieties are reacted with Fischer-Tropsch/gas-to-liquids reaction products and/or by-products (e.g., gas-to-liquids-produced α-olefins) to yield bio-derived diester species that can then be selectively blended with base oil and one or more additive species to yield an application-specific finished lubricant product having a biomass-derived component.

APPLICATION-SPECIFIC FINISHED LUBRICANT
COMPOSITIONS COMPRISING A BIO-DERIVED ESTER
COMPONENT AND METHODS OF MAKING SAME
{30611 This mvention relates to finished lubricant compositions and ther manufacture, and specifically to application-specific finished lubricant compositions comprising a diester component—particularly wherein the diester component is at least partially derived from biomass.
10862] Hsters have been used as lubricating oils for over 50 years. They arc used na variety of applications ranging from jet engines to refrigeration. In fact, esters were the first synthetic crankcase motor oils in automotive applications. However, esters have largely given way to polvalphaolefins (PAQOs) due to the lower cost of PAQs and their formulation sirailarities fo moineral oils. To fully synthetic motor oils, however, esters are almost always used in combination with PAOs fo balance the effect on seals, additive solobility, volatility reduction, and energy efficiency improvement by enhanced hubricity.
[0883] Ester-based hibricants, in general, have excellent hubrication properties due to the polarity of the ester molecules of which they are comprised. Due to the polarity of the ester functionality, esters have a stronger affinity for metal surfaces than PAUs and mineral oils. As a result, they are very effective in establishing protective fibus on metal surfaces, such protective films serving to mitigate the wear of such metals. Such lubricants arc less volatile than the traditional lubricants and tend to have much higher flash points and much lower vapor pressures. Ester lubricants are excelent solvents and dispersants, and can readily solvate and disperse the degradation by-products of oils, i.e, they greatly reduce sludge buildup. While ester lubricants are relatively stable to thermal and oxidative processes, the ester functionalities give microbes a handle with which to do their biodegrading more efficiently and more effectively than their mineral oil-based analogues——therehby rendering them more environmmentally-friendly. However, as previously alluded to, the preparation of esters is more involved and more costly than that of their PAO counterparts.
[0804] Recently, novel diester-based lubricant compositions and ther corresponding mamifacture have been described in Miller et al, United States Patent Application
Publication No. 20080194444 Al, published Aug. 14, 2008; and m Miller et al, United
States Patent Publication No. 20090198075 Al, published Aung. 6, 2009. The diester syntheses described in these patent applications render the economics of diester lubricant fornnddations more favorable.
[0885] In view of the foregoing, and not withstanding such above-described advances, further integration of such diester-based lubricant synthesis with one or more other processes, particularly those further involving the conversion of low value by-products nto application-specific finished lubricant compositions, can further shift the economies of ester-based lubricant manufacture in a favorable direction.
[0806] The present invention is generally directed to methods of making apphication- specific finished lubricant compositions comprising bio-derived diester species. In sore embodiments, bio-derived fatty acid moicties are reacted with Fischer-Tropsch (FTV gas-to-liquids (GTL) reaction products and/or by-products (i.e., w-oleting) to yield bio-derived diester species that can then be selectively blended with base stock (oil) and one or more additive species to yield an application-specific fimished lubricant product having a biomass-derived component.
[3807] In some embodiments, the present invention is direcled to processes for making such above-mentioned finished lubricant compositions, said processes generally comprising the steps oft (a) preparing a quantity of epoxidized olefins, wherein said step of preparing comprises the sub-steps oft (i) isolating alpha-olefins (v-olefins} made from a gas-to-Hquids process to yield isolated o-olefing; (it) isomerizing at least a majority of the isolated a-olefins to yield a quantity of internalized clefing; and (11) epoxidizing at least a majority of the internalized olefins to form a quantity of epoxidized olefins comprising an epoxide ring; and (b) obtaining a quantity of esterification agents, the

esterification agents being derived from triglyceride-borne fatty acid moieties, whereby said derivation vields esterification agents selected from the group consisting of carboxylic acids, acyl halides, acyl anhydrides, and combinations thereof; wherein the step of obtaining comprises the sub-steps ofr (3) selecting a biomass source comprising triglycerides, said triglycerides comprising fatty acid moieties of appropriate length; (317) liberating a majority of the fatty acid moieties from the triglyceride molecules of which they are a component so as to yield esterification agents; {¢} esterifving at least a majority of the epoxidized olefins with the esterification agents so as to yield a quantity of diester species; and {d) combining the quantity of diester species with a quantity of base oil and an additive component comprising at least one additive selected from the group consisting of antioxidants, detergents, anti-wear agents, metal deactivators, corrosion inhibitors, rast inhibitors, friction modifiers, anti-foaming agents, viscosity index improvers, demulsifying agents, emulsifying agents, tackifiers, complexing agents, extreme pressure additives, pour point depressants, and combinations thereof, wherein selection of the at least one additive is directed largely by the end-use of the lubricant composition being made, wherein said lubricant composition can be of a type selected from the group consisting of turbine oils, metalworking fluids, hydraulic fluids, compressor oils, chain oils, farm equipment engine oils, tractor hydraulic fluids, marine oils, paper machine oils, spmdle and textile oils, trailer wheel bearing greases, and combinations thereof.
[0838] Typically, the finished lubricant compositions produced by the above-mentioned processes comprise, together with a base oil (base stock) and one or more additive species, a quantity of at least one diester species, the diester species generally baving the following structure: 0

I. Introduction
[3618] As mentioned m a preceding section, the present mvention is directed to methods of making application-specific lubricant compositions having a bilomass-derived component. In some embodiments, bio-derived (i.e., derived from a renewable biomass source} fatty {carboxylic} acid moieties are reacted with Fischer-Tropsch (FT) gas-to- hguids (GTL} reaction products and/or by-products (i.e., a-clefins) to vicld bio-derived diester species that can then be selectively blended with base stock {oil} and one or more additive species to yield an apphication-specific finished lubricant product having a biomass-derived component.
[0819] Because biolubricants and biofuels are increasingly capturing the publics attention and becoming topics of focus for many to the oil industry, the use of biomass in the making of such above-mentioned finished lubricants could be attractive from several different perspectives (e.g., renewability, regulatory, cconomic, ¢ic.). As biomass is utilized in the making of the diester component of the finished lubricants described herem, such lubricants are deemed to be biolibricants—or at the very least, they are deemed to comprise a bio-derived component. 2. Definitions
[3620] “Lubricants,” as defined herein, are substances (usually a fluid under operating conditions) mtroduced between two moving surfaces so io reduce the friction and wear between them. This definition is intended to include greases, whose viscosity drops dramatically upon application of shear.
[0821] Herem, “base oil” will be understood to mean the single largest component (by weighty of a lubricant composition. Base oils are categorized into five groups (I-V) by the American Petroleum fnstitute (AP). See API Publication Number 1509. The API
S55.
Base Gil Category, as shown in the following table {Table 1), is used to define the compositional nature and/or origin of the base oil.
Table 1.
Base Oil Category Suifur {%) Saturates {%) ¥iscosity index
Group | >{3.03 and/or <0 8G to 120
Group fi <0.03 : and >40 80 to 120
Group II | <003 | and >a0 >120
Group IV All polyalphaolefins (PAOs)
Group V All others not included in Groups | I}, Hor IV {e.q., esters) 10022] “Mineral base oils,” as defined herein, are those base oils produced by the refining of a crude oil.
J3323] “Pour point,” as defined herein, represents the lowest temperature at which a fluid will pour or flow. See, e.g., ASTM international Standard Test Method D 5950-02 (R 20067). 10024] “Cloud point,” as defined herein, represents the temperature al which a fhnd begins to phase separate due to crystal formation. See, c.g, ASTM Standard Test
Method D 5771-05.
[0825] “Centistoke,” abbreviated “cSt,” is a unit for kinematic viscosity of a fluid (e.g. a lubricant), wherein 1 centistoke equals 1 millimeter squared per second (1 ¢5t = mm/s). See, e.g., ASTM Standard Guide and Test Method D 2270-04. Herein, the units ¢St and mm/s are used interchangeably.
[6526] With respect to describing molecules and/or molecular fragments herein, “Ru,” where “m” is an index, refers to a hydrocarbon group, wherein the molecules and/or molecular fragments can be linear and/or branched. - 6H -
00271 As defined herein, “C,” where “n” is an integer, describes a hydrocarbon molecule or fragment (e.g, an alkyl group) wherein “n” denotes the number of carbon atoros in the fragment or molecule,
[0028] The term “carbon number” is used herein in a manner analogous io that of “C,.”
A difference, however, is that carbon mumber refers to the total number of carbon atoms m a molecule (or molecular fragment) regardless of whether or not tis purely hydrocarbon in nature. Linoleic acid, for example, has a carbon number of 18. 10029] The term “internal olefin,” as used herein, refers to an olefin (ie., an alkene) having a non-terminal carbon-carbon double bond (C=C). This is in contrast to “o- olefins” which do bear a terminal carbon-carbon double bond.
[8030] The term “vicinal,” as used herein, refers fo the attachment of two functional groups (substituents) to adjacent carbons in a hydrocarbon-based molecule, e.g., vicinal digesters.
[3631] The term “fatty acid moiety,” as used herein, refers to any roolecular species and/or molecular fragment comprising the acyl component of a fatty (carboxylic) acid. {3032 The prefix “bin,” as used herein, refers to an association with a renewable resource of biological origin, such as resource generally being exclusive of fossil fuels.
Such an association is typically that of derivation, i.c., a bio-ester derived from a biomass precursor roaterial.
[0033] “Fischer-Tropsch products,” as defined herein, refer to molecular species derived from a catalytically-driven reaction between CO and H; (i.e, “syngas™). See, e.g, Dry, “The Fischer-Tropsch process: 1950-2000,” vol. 71(3-4), pp. 227-241, 2002; Schulz, “Short history and present trends of Fischer-Tropsch synthesis,” Applied Catalysis A, vol. 186, pp. 3-12, 1999; Claeys and Van Steen, “Fischer-Tropsch Technology,” Chapter 8, pp. 623-665, 2004.
[0034] “Gas-to-liquads,” as used herein, refers to Fischer-Tropsch processes for generating liquid hydrocarbons and hydrocarbon-based species (e.g., oxygenates).
[0835] “Apphcation-specific finished lubricant compositions,” as described herein, refers to lubricant compositions formulated for a specific end-use.

(201c) epoxidizing at least a majority of the internalized olefins to form a quantity of epoxidized olefins comprising an cpoxide ring: and (202) obtaining a quantity of esterification agents, the esterification agents being derived from triglyceride-borme fatty acid moieties, whereby said derivation yields esterification agents selected from the group consisting of carboxylic acids, acyl halides, acyl anhydrides, and combinations thereof; wherein the step of obtaining comprises the sub-steps oft (202a) sclecting a biomass source comprising trigiveerides, said triglycerides comprising fatty acid moieties of appropriate length (being proportional to carbon number); (202b) liberating a majority of the fatty acid moigtics from the triglyceride molecules of which they arc a component so as fo yickd esterification agents; (203) esterifying at least a majority of the epoxidized olefins with the esterification agents so as to yield a quantity of diester species; and (204) combining the quantity of diester species with a quantity of base oil and an additive component comprising at least one additive selected from the group consisting of antioxidants, detergents, anti-wear agents, metal deactivators, corrosion mhibitors, rust inhibitors, {friction modifiers, anti-foaming agents, viscosity index improvers, denwlsifying agents, emulsifying agents, tackifiers, complexing agents, extreme pressure additives, pour point depressants, and combinations thereof; wherein selection of the at least one additive 1s directed largely by the end-use of the lubricant composition being made, wherein said labricant composition can be of a type selected from the group consisting of turbine oils, metalworking fluids, hydraulic fhuds, compressor oils, chain oils, farm equipment engine oils, tractor hydraulic fluids, marine oils, paper machine oils, spindle and lextile oils, trailer wheel bearing greases, and combinations thereof.
[36342] The GTL process by which the c-olefins are produced can be a low-temperature (200-300°C) Fischer-Tropsch (LTFT)} process, a high-temperature Fischer-Tropsch (HTFT} process (>300°C), or some combination of the two. In addition, in some such erobodiments, the GTL process may further chide one or more additional processes subsequent to the initial Fischer-Tropsch synthesis. 0843] In some such above-described processes, the sub-step of isolating the a-olefios comprises their separation from a largely paraffinic GTL product. Such separation can be effected via a variety of techniques inchuding, but not hited to, distillation, fractionation, membrane separation, phase separation, and combinations thereof.
0044] In some such above-described processes, the sub-siep of isomerizing involves use of an olefin isomerization catalyst such as, but not limited to, crystalline aluminosilicate and like materials and aluminophosphates. See, e.g., Schaad, United States Patent No. 2,537,283, issued fan. 9, 1951; Holm et al, United States Patent No. 3,211,801, issued
Oct. 12, 1965; Noddings of al, United States Patent No. 3,270,085, issued Aug. 30, 1966; Noddings, United States Patent No. 3,327,014, issued Jun. 20, 1967; Miisutani ot al., United States Patent No. 3,304,343, issued Feb. 14, 1967; Holm et al., United States
Patent No. 3,448,164, issued Jun. 3, 1969; Johnson et al, United States Patent No. 4,593,146, issued Jun. 3, 1986; Tidwell ¢t al, United States Patent No. 3,723,564, issued
Mar, 27, 1973; and Miller, United States Patent No. 6,281,404, issued Aug. 28, 2001; the last of which claims a crystalline aluminophosphate-based catalyst with |-dimensional pores of size between 3.8 A and 5 A. 0845] Regarding the above-mentioned sub-step of epoxidizing (ie, the epoxidation step), In some embodiments, the above-described olefin (having been internalized from an o-olefin) can be reacted with a peroxide (e.g, HO: or a peroxy acid (c.g. peroxyacetic acid} to generate an epoxide. See, ¢.g., Swern ct al, “Epoxidation of Oleic
Actd, Methyl Oleate and Oley! Alcohol with Perbenzoic Acid,” I. Am. Chem. Soc., vol. 66(11}, pp. 1925-1927, 1944. 0846] Tn some such above-described processes, the sub-step of liberating triglyceride- borne fatty acid moieties comprises hydrolyzing the triglycerides to yield glycerol and carboxylic acids, the latfer being operable for use as esterification agents (see, c.g.
Huber et al., “Synthesis of Transportation Fuels from Biomass: Chenusiry, Catalysts, and
Engineering,” Chem. Rev., vol. 106, pp. 4044-4098, 2006). In some such embodiments, there further comprises a sub-siep of substantially separating the carboxylic acids on the basis of their degree of unsaturation so that the esterification agents used in the subsequent step of esterifying are substantially homogeneous in terms of their degree of unsaturation. See Miller, United States Patent Application Publication No. 20090285728
Al, published Nov. 19, 2009. {0047} In some such above-described processes, the step of esterifving the epoxidized olefins proceeds through a diol mtermediate (see Miller et al, United States Patent
Application Publication No. 20080194444 Al, published Aug. 14, 2008}. Such a diol mterroediate can be generated via epoxide ring opening to yield the corresponding diol,
wherein this ring opening 18 effected via acid-catalyzed or based-catalyzed hydrolysis.
Exeraplary acid catalysts include, bul are not limited to, mineral-based Brénsted acids {e.g., HCI, HyS04, HsPOy, perhalogenates, etc.), Lewis acids (e.g., TiCly and AICh) solid acids such as acidic aluminas and silicas or their mixtures, and the hike. See, e.g., Parker et al, “Mechanisms of Epoxide Reactions,” Chem. Rev., vol. S94), pp. 737-799, 1959; and Paterson ef al., “meso Epoxides in Asynumetric Synthesis: Enantioselective Opening by Nucleophiles in the Presence of Chiral Lewis Acids,” Angew. Chem. Int. Ed, vol. 319), pp. 1179-1180, 1992. Based-catalyzed hydrolysis typically involves the use of bases such as aqueous sofutions of sodium or potassium hydroxide.
[8848] In some such embodiments, the diol intermediate 18 reacted with the esterification agent in the presence of an acid catalyst. Shown in Scheme 1 (Fig. 3), is an exemplary such pathway that proceeds through a diol species en route to a diester species, wherein mn some such embodiments the diester species so formed can subsequently be meorporated, as the diester component or a portion thereof, into a finished lubricant composition.
[3649] In some such above-described processes, the step of esterifying the epoxidized olefins is carried directly via reaction between the epoxidized olefin and the esterification agent {sce Miller et al, United States Patent Application Publication No. 20090198075
Al, published Aug. 6, 2009). In some such embodiments, the step of esterifying the epoxidized olefins is carried out in the presence of an acid catalyst, wherein the acid catalyst can be selected from the group consisting of HaPQO,, Ha80,, sulfonic acid, Lewis acids, silica and alumina-based solid acids, amberlyst, tungsten oxide, and combinations thereof. In some embodiments, during the step of directly esterifying, efforts are made to remove water produced as a result of the esterifying process. Such efforts can positively irapact the diester yield. Shown in Scheme 2 (Fig. 4) is an excraplary such pathway that procecds via direct esterification of the epoxide species en route to a diester species.
[08580] In some such above-described processes, the sub-step of cpoxidizing is enzymatically-facilitated (see Miller ot al, United States Patent Application Serial No. 12/276,235, filed Nov. 13, 2008). Shown in Scheme 3 (Fig. 5) is an exemplary such pathway, wherein the epoxidation of the internalized olefin is enzymatically-facilitated or mediated. While Scheme 3 depicts an exemplary pathway that procceds via direct esterification of the epoxide species {en route to a diester species), such epoxidation could alternatively proceed through a diol species.
[3051] In some such above-described processes, the diester species formed is selected from the group consisting of decanoic acid 2-decanoyloxy-1-hexyl-octyl ester and its isomers, tetradecanoic acid-1-hexyl-2-tetradecanoylioxy-octyl esters and its isomers, dodecanoic acid 2-dodecanoyloxy- I-hexyl-octy] ester and is isomers, hexanoie acid 2- hexanoyloxy-1-hexyl-octyl ester and its isomers, octanoic acid 2-octanoyloxy-1-hexyl- octyl ester and its isomers, hexanocic acid 2-hexancyloxy-i-pentyl-heptyl ester and isomers, octanoic acid 2-octanoyloxy-1-pentyl-heptyl ester and isomers, decanoic acid 2- decanoyloxy-1-pentyl-hepty! ester and isomers, decanoie acid-2-decanoyloxy- 1 -pentyi- heptyl ester and its isomers, dodecanoic acid 2-dodecanoylony-1-pentyl-heptyl ester and isomers, tctradecanocic acid 1-pentyi-2-tetradecanoyloxy-heptyl ester and isomers, tetradecanoic acid 1-butyl-2-tetradecanoyloxy-hexyl ester and isomers, dodecanoic acid -butyi-2-dodecanoyloxy-hexyl ester and isomers, decanoie acid 1-butyl-2-decanoyioxy- hexyl ester and isomers, octancic acid i-butyl-Z-octanoyloxy-hexyl ester and isomers, hexanoie acid 1-butyl-2-hexanoyloxy-hexyl ester and isomers, tetradecanocic acid 1- propyl-2-tetradecanoyloxy-pentyl ester and isomers, dodecanoic acid 2-dodecanoyloxy-
I-propyl-pentyl ester and isomers, decanoic acid 2-decanoyloxy-1-propyl-pentyl ester and isomers, octancic acid 2-octanoyioxy-1-propyl-pentyl ester and isomers, hexanoic acid 2-hexanovloxy-1-propyi-pentyl ester and isomers, and mixtures thereof. 10052] In some such above-described processes, wherein, in the step of combining, the base oil is selected from the group consisting of GTL base oils, mineral base oils, diester- based base oils, and mixtures thereof In some such embodiments, the base thud is a
GTL base oil or a diester-based base oil.
[0853] To some embodiments, all or part of the additive component is provided as an additive package. In some or other embodiments, some or all of the diester component is combined with some or all of the additive component to collectively from an additive package. In some embodiments, the quantity of diester component, or a portion thereof, serves to facilitate dispersion of all or part of the additive component into the base oil,
For more on the variety of lubricant additives that exist, and on the properties they impart, see, e.g., Rudnick, LR. Lubricant Additives: Chemistry and Applications, 2" ed. (CRC Press, Boca Raton, 2009,
[3884] In some such above-described processes, the sob-step of selecting a biomass source comprising triglycerides is based on identification and sufficient content of triglyceride molecules bearing fatty acid rooicties of length more desirably suitable for use as a particular lubricant composition. For example, tno its hydrolyzed form, palm oil comprises approximately 44 percent palmitic acid, a saturated fatty acid with a carbon number of 16.
[3855] In some such above-described processes, the lubricant composition is a hydraulic fluid having a pour point of from about -80°C to about 0°C.
[3056] In some such above-described processes, the lubricant composition is a turbine oil having a viscosity index (VI) of from at least 90 to at most 130, and having an
RPVOT oxidative stability of from at least 250 min. to ai most 2300 min, See ASTM
Standard Guide and Test Method 13 2272-02
I0057] In some such above-described processes, the lubricant composition is a metalworking fluid having a pour point of from about 206°C to about 0°C. Such metalworking fhads typically have a viscosity m the range of from about 32 centistokes {cSt} to about 220 cSt—measured at 46°C.
[0058] In some such above-described processes, the lubricant composition is a compressor oil having a VI of from at least 90 to at most 130, and having a pour point of from at least -60°C fo at most 80°C. Such compressor oil typically has a viscosity in the range of from about 32 ¢St to about 220 cSt—measured at 40°C.
[0059] In some such above-described processes, the fubricant compesition 1s a chain oil having a VI in the range of from at feast 50 to at most 130, and having an aniline point in the range of from at least 0°C to at most 130°C, 5. Variations
[3068] Vanations (i.e., alternate embodiments} on the above-described methods of making apphication-specific lubricant compositions include, but are not hmited to, integrating such methods with one or more other processes to produce one or more other related or different products, and/or to enhance the products being made by one or more of the above-described method embodiments.
[3061] As an example of such an above-described vanational embodiment, Scheme 4 (Fig. 6} illustrates an exemplary method embodiment of the present invention, wherein diester synthesis proceeds via a direct esterification of an epoxide species. In this scheme, a fractional crystallization process 1s used to separate saturated fatty acids from unsaturated fatly acids, whereby the saturated fatty acids are used in the direct esterification (sec Miller, United States Patent Application Publication No. Z00%028572¢
Al, published Nov. 19, 2009). In some such contemplated variational embodiments, the unsaturated fatty acids can be hydroprocessed to yield saturated fatty acids that are subsequently recycled back into the direct esterification sub-process. Additionally or alternatively, the unsaturated fatty acids can be reacted to form triester and/or diester species that are used in other compositions or in the finished lubricant coropositions described herein (see, e.g., Elomart et al, United States Patent Application Serial No. 12/480,032, filed June 8, 2009; and Elomari ¢t al, United States Patent Application
Serial No. 12/498,663, filed July 7, 2009).
[0062] Naturally, the above-described variational embodiment could be modified such that the esterification proceeds through a diol species, as is depicted in Scheme 5 (Fig. 7. Additionally, either of these variational embodiments depicted in Schemes 4 and 5 could utilize enzymes to facilitate the epoxidation of the internalized olefins. 10063] Additionally or alternatively, in some variational embodiments the FU/GTL process can be tuned or otherwise tailored to produce a-olefins as the primary product stream, and/or with high yields of o-olefing of specific cham length/carbon number.
Separation sub-processes can be employed fo further refine the g-olefin type that is vitimately epoxidized en route to diester formation, in accordance with some ernbodiments of the present mvention. 6. Examples
