JP4625456B2 - Vegetable oil lubricant containing all hydrotreated synthetic oil - Google Patents

Description

  This application claims the priority of provisional application 60 / 502,669 filed on September 12, 2003.

  The present invention is directed to a lubricating oil composition. Specifically, the present invention relates to a vegetable oil-based lubricant containing a synthetic oil produced by a total hydroprocessing route. More specifically, the present invention has improved properties including viscosity index, pour point, cold pumpability, low volatility, oxidation stability, electrical insulation value, ability to formulate various viscosities and microbial biodegradability. It relates to the lubricant to be provided.

  In general, it is known that vegetable oil-based lubricants can be formed using an additive containing a non-lubricating oil component of a natural vacuum gas oil feedstock. Historically, base oil manufacturers have often used traditional chemical solvent refining processes to remove unwanted non-lubricating oil molecules from the gas oil portion of crude oil. Such a purification process is considered a subtraction process in that the solvent does not change the molecular structure of the desired product. In order to further improve the properties of solvent refined base oils, hydrogenation (ie hydrorefining) is sometimes used to saturate the molecules and make them less susceptible to oxidative degradation when used as a lubricant. In general, hydrorefining combined with solvent processes, while useful, is generally recognized as being very benign and hardly alters the primary, secondary and tertiary structure of the treated product.

  The viscosity index (VI) is a measure of the resistance of the oil to changes in viscosity as the temperature changes. The greater the VI, the less the viscosity changes over a wide temperature range. In other words, the higher the VI, the better the oil will provide better lubricant performance at both extreme temperatures without becoming viscous at low temperatures or low viscosity at high temperatures.

  Hydrocracking and hydroisomerization are refining processes that produce high quality lubricant base oils using catalyst and hydrogen at high pressure. Hydrocracking is used to improve VI and remove impurities, while hydroisomerization converts wax molecules into high quality lubricant components.

  Groups I, II and III are broad base oil feedstock categories developed by the American Petroleum Institute to create guidelines for authorizing engine oils. Usually, solvent refined base oils are classified as Class I, while hydrotreated base oil feeds belong to Class II. Special base oils (UCBOS) or ultra-high VI feeds are usually classified as class III.

  Although II + is not an official API (American Petroleum Institute) designation, it is increasingly being used to describe higher VI (110-119) and lower volatility II feeds than normal Class II feeds. It is a certain term.

  Group I oils contain high levels of sulfur and aromatics. Sulfur and aromatic compounds are compounds that can reduce performance. Hydrotreated Group II and Group III oils have low levels of these impurities, improving the oxidation performance of the final formulated lubricant.

  Recent synthetic processes have led to the emergence of new synthetic oil types. For example, titled “Synthetic Properties of Group III Base Oils” reported at the 1999 Lubricating Oil and Wax Conference, November 11-12, Houston, TX (National Petrochemical and Petroleum Refining Association) The technical paper of Chevron Products Company combines three catalytic processes to significantly and selectively change molecular size, shape and heteroatom content to improve the lubricating properties of the molecule A total hydrotreating manufacturing path is disclosed. In order to produce a very stable oil, hydrogen is added at high temperature and pressure in all three steps. Impurities such as sulfur and nitrogen are virtually completely removed. In the production of Class III, the raw material is converted to a saturated compound with increased isoparaffins. Reactive species such as aromatics, sulfur and nitrogen containing species are substantially completely removed, and species that cause problems with low temperature performance such as normal paraffins are also removed. This paper finally describes the conclusions of raw material and product analysis from commercial Class III production operations, according to which most raw molecules produce the latest all hydrotreated Group III base oils. Has been synthetically altered by the three catalytic processes used to achieve this. These results suggest that the latest Group III base oils produced using the full hydrotreating route are, in effect, artificial or synthetic, superior to the hydrocracking base oils of the prior art. To support. In addition, the latest Group III base oils have high performance in lubricant applications and should be used in high performance products that are often formulated using traditional synthetics such as polyalphaolefins (PAO). Can do. This document does not teach the use of all hydrotreated Group III base oils as a feedstock for the preparation of biodegradable vegetable oil-based lubricants.

  Patents that generally disclose lubricants that can be formed using vegetable oils and Group III oils include all US Pat. No. 6,103 from Lubrizol Corporation (Wicklife, Ohio). , 673, US Pat. No. 6,251,840, US Pat. No. 6,451,745 and US Pat. No. 6,528,458. Other patents include US Pat. No. 6,303,547 and US Pat. No. 6,444,622, both from Ethyl Corporation (Richmond, VA).

  US Pat. No. 6,528,458 includes (a) an oil of lubricating viscosity, (b) 2,5-dimercapto-1,3,4-thiadiazole (DMTD), a derivative of DMTD or a mixture thereof, A composition comprising (c) a friction modifier, and (d) a dispersing agent undergoes gear shifting by a process including synchronization of engaged and disengaged partial transmission shafts and engagement of a wet clutch. It is disclosed that it is useful for lubricating a transmission having a plurality of wet clutches and a plurality of partial transmission shafts.

  US Pat. No. 6,451,745 provides a continuously variable transmission with a composition comprising (a) an oil of lubricating viscosity, (b) a dispersant, and (c) a detergent. It is disclosed that the continuously variable transmission can be lubricated. At least one of the dispersant (b) and the detergent (c) is a borate species and the amount of boron present in the composition provides improved friction and anti-seizure properties when used in the transmission. Sufficient to apply to the composition.

U.S. Patent No. 6,444,622, and at least one _C 5 _{-C 60} carboxylic acids, guanidine, and at least one amine selected from the group comprising aminoguanidine, urea, thiourea, and salts thereof It is disclosed that a mixture of the above reaction product and a phosphorus-containing dispersant is useful as a gear oil additive.

US Pat. No. 6,303,547 includes at least one C _{5 to} C ₆₀ carboxylic acid and at least one amine selected from the group comprising guanidine, aminoguanidine, urea, thiourea and salts thereof. Of the reaction product is useful as a gear oil additive.

  US Pat. No. 6,251,840 discloses a lubricating / functional fluid composition that exhibits improved antiwear and antifoam properties in use. The improvement results from the combined use of 2,5-dimercapto-1,3,4-thiadiazole and its derivatives with silicone and / or fluorosilicone antifoam agents.

  US Pat. No. 6,103,673 describes a lubricant viscosity oil, a shear stable viscosity modifier, at least 0.1 weight percent base excess metal salt, at least 0.1 weight percent at least one phosphorus. Compositions composed of a compound and a combination of 0.1 to 0.25 weight percent of at least two friction modifiers are disclosed to provide improved fluids for continuously variable transmissions. At least one of the friction modifiers is selected from the group comprising zinc salts of fatty acids having at least 10 carbon atoms, hydrocarbyl imidazolines containing at least 12 carbon atoms in the hydrocarbyl group and borated epoxides. The total amount of friction modifier is limited to an amount that provides a metal-to-metal coefficient of friction of at least about 0.120 as measured by ASTM-G-77 at 110 ° C.

  The literature does not disclose that it allows lubricant formulations (Class III) containing a combination of vegetable oil and hydrotreated base oil, and therefore does not provide the advantages associated with such formulations. . Because all hydrotreated Group III feedstocks are produced without a solvent refining step, the purity is far above that of Class II or Group III base oils produced in “hybrid” plants that adhere to the solvent process process. Yes. In fact, all hydrotreated Group III feedstocks contain the lowest levels of impurities available today in mineral oils, thereby receiving significant performance advantages.

  The total hydrotreatment includes three steps of hydrocracking, hydroisomerization and hydrorefining as follows. In the first stage hydrocracking, most of the sulfur, nitrogen, and all other non-hydrocarbon impurities are effectively removed, and most aromatics are saturated by hydrogenation. As the ring is opened and the paraffin isomers are redistributed as driven by thermodynamics and accelerated by the catalyst, molecular remodeling of the remaining saturated species takes place. Low-contamination fuel is a byproduct of this step and the next step of the process. In the second stage hydroisomerization, n-paraffins and other molecules with wax side chains are isomerized into branched molecules with much lower pour points. Most of the remaining aromatic compounds are saturated and most of the remaining sulfur and nitrogen species are removed. The final hydrotreating removes any remaining non-isoparaffin impurities (sulfur species, nitrogen species, aromatics and olefins) to trace levels.

  Environmental problems associated with waste lubricants and / or used lubricants are also problems that need to be addressed. For example, biodegradable resistant lubricants can stress ecosystems if they are improperly discarded or accidentally released into the environment. The invasiveness and persistence of such materials continues to be a health problem in aquatic and landfill environments. To overcome these problems, research efforts continue to search for new raw materials and / or new raw material combinations that provide improved lubricants with a higher degree of microbial degradability.

  All patents teaching biodegradable lubricants are from Renewable Lubricants, Inc. (Hartville, Ohio), the contents of which are incorporated herein by reference. US Pat. No. 5,736,493, US Pat.
