Description

Vegetable oil lubricant comprising all-hydroprocessed synthetic oils

The present invention relates to a lubricating oil composition. In particular, the present invention relates to vegetable oil-based lubricants comprising synthetic oils prepared by pre-hydrogenation routes. More specifically, the present invention relates to lubricants that provide improved properties including viscosity index, pour point, low temperature pumpability, low volatility, oxidative stability, electrical insulation value, ability to form different viscosity and microbial biodegradability.

It is generally known that vegetable oil-based lubricants can be formed using additives comprising non-lubricating oil portions of natural vacuum gas oil raw materials. Historically, base oil manufacturers have often used traditional chemical-solvent purification processes to remove undesirable non-lubricating oil molecules from the gas oil portion of crude oil. This purification process is considered a subtraction in that the solvent does not alter the molecular structure of the desired product. In order to further enhance the characteristics of solvent purified base oils, hydrogenation (ie, hydrogen processing) can sometimes be used to saturate the molecules, making them less susceptible to oxidative degradation when used as lubricating oil. Hydroprocessing associated with solvent processing is useful but typically very mild, resulting in less variation in the primary, secondary and tertiary structures of the processed product.

Viscosity index (VI) measures the resistance of oil to viscosity change with temperature change. The higher the VI, the more stable the viscosity over the wide temperature range. That is, the higher the VI, the less oil will thicken as the temperature cools and less dilute at high temperatures, providing good lubrication at both temperature extremes.

Hydrocracking and hydroisomerization are refining processes that produce advanced lubricant base oils using catalysts and hydrogen at high temperatures. Hydrocracking is used to enhance VI and remove impurities, while hydroisomerization converts wax molecules into higher lubricating oil components.

Groups I, II, and III are a broad class of base oil raw materials developed by the American Petroleum Institute (API) to create guidelines for engine oil licensing. Typically, solvent-purified base oils belong to group I, while the hydrotreated base oil raw materials belong to group II. The new concept of base oil (UCBO) or ultrahigh viscosity index raw materials is usually classified in Group III.

Although not an official API representation, Group II + is an increasingly used term to describe Group II raw materials that are higher than VI (110-119) but less volatile than typical Group II raw materials.

Group I oils contain large amounts of sulfur and aromatics, compounds that can reduce performance. Hydrotreated Group II and III oils have lower impurity content resulting in improved oxidation performance in fully formulated lubricating oils.

Recent refining treatments have formed a new class of synthetic oils. For example, a paper published by Chevron Products Company, titled "The Synthetic Nature of Group III Base Oils" on November 11-12 at the 1999 Lubricants & Waxes Meeting (National Petrochemical & Refiners Association), Houston, TX, USA An all-hydroprocessing manufacturing route is disclosed that combines three catalytic processes that significantly and selectively alter the size, shape and heteroatom content of molecules to improve properties. Hydrogen is added at high temperature and pressure in a total of three steps to make the oil extremely stable. Impurities such as sulfur and nitrogen are necessarily completely removed. For group III production, the raw material is converted to saturated material, which is concentrated in isoparaffin. Reactive species such as aromatics, sulfur, and nitrogen-containing substances are substantially eliminated, and species that are problematic in relation to low temperature performance, usually paraffin, are also removed. Finally, the paper found that raw material molecules in the production of commercially available Group III compounds showed that the majority of raw material molecules were synthesized by three catalytic processes used to produce modern, pre-hydrogenated Group III base oils. Shows the change. These results show that modern Group III base oils made using pre-hydrogenation pathways are inherently man-made or synthetic and have advantages over hydrocracked base oils made by old techniques. In addition, their high performance in lubricating oil applications allows them to be formulated by traditional synthesis such as polyalphaolefins (PAO) and used in high performance products. This reference does not suggest the use of pre-hydrogenated Group III base oils as raw materials for the preparation of biodegradable vegetable oil-based lubricants.

The references do not disclose lubricating oil formulations containing combinations of vegetable oils and hydrotreated base oils (Group III) and therefore do not suggest or suggest any benefits associated with such formulations. Since pre-hydrogenated Group III base oils are prepared without a solvent purification step, when it comes to purity, they are far superior to Group II or Group III base oils produced in “hybrid” plants that maintain some solvent treatment. In fact, they contain the lowest levels of impurities present in mineral oils, which offer significant performance advantages.

Pre-hydrogenation involves three steps: hydrocracking, hydroisomerization, and hydrogenation reforming. In the first step, hydrocracking, most of the sulfur, nitrogen and substantially all other non-hydrocarbon impurities are removed and most aromatics are saturated by hydrogenation. Molecular remodeling of the remaining saturated species occurs as ring opening and redistribution of the paraffin isomers are carried out by thermodynamics with reaction rates promoted by the catalyst. Clean fuel is a byproduct of this process and the next process step. In the second step, hydroisomerization, the other molecules with n-paraffins and waxy side chains are isomerized into side chain molecules with much lower pour points. Most of the remaining aromatics are saturated and most of the remaining sulfur and nitrogen species are removed. In the last step, hydrogenation, the remaining non-isoparaffin impurities (sulfur species, nitrogen species, aromatics, and olefins) are removed to trace levels.

Environmental issues related to the waste and / or spent lubricants should also be solved. For example, improper disposal of non-biodegradable lubricants or accidental release to the environment can stress the ecosystem. The aggressive and persistent nature of these materials can be a health problem in water and land environments. To address this problem, research continues to provide new raw materials and / or combinations of new raw materials to provide improved lubricants with high microbial biodegradability.
