  The present invention relates to a lubricant composition. Specifically, the present invention relates to a vegetable oil-based lubricant comprising a synthetic oil produced from a Fischer-Tropsch gas by a liquid (FTGTL: Fischer Tropsch Gas to Liquids) process. More specifically, the present invention provides enhancements including viscosity index, pour point, cold pumpability, low volatility, oxidation stability, electrical insulation value, ability to formulate various viscosities and biodegradability by microorganisms. The present invention relates to a lubricant that provides improved properties.

  In general, it is well known that vegetable oil lubricants can be formed using additives that include the non-lubricating oil portion of the 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 purification is considered a subtractive process in that the solvent does not change the molecular structure of the desired product. Hydrogenation (ie, hydrorefining) to further enhance the properties of solvent-refined base oils by saturating molecules and reducing the impact on oxidative degradation when used as a lubricant ) May be used. In general, hydrorefining with solvent processes is useful but generally recognized to be very mild and result in minor changes in the primary, secondary and tertiary structure of the finished product.

  The viscosity index (VI) is a measure of the resistance of the oil to changes in viscosity as the temperature changes. As VI increases, the viscosity becomes more stable over a wide temperature range. In other words, as VI increases, the oil does not thicken as it cools and does not become less viscous at higher temperatures, providing good lubricant performance at both extreme 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, and hydroisomerization converts wax molecules into high quality lubricant components.

  Groups I, II and III are broad classifications of base oil feedstocks created by the American Petroleum Institute to create guidelines for authorizing engine oils. Typically, solvent refined base oils are classified as Class I, and hydrotreated base oil feedstocks are classified as Class II. Unconventional base oils (UCBO) or ultra-high VI feeds are usually classified as class III.

  Class II + is not an official API designation, but is increasingly used to represent a Class II ingredient that is higher in VI (110-119) and less volatile than a typical Class II ingredient. It is a term that has become.

  Group I oils contain high levels of sulfur and aromatics, which are compounds that can reduce performance. Hydrotreated Group II and Group III oils have lower levels of these impurities, resulting in increased oxidation performance of the fully formulated lubricant.

  Recent refinement processes have resulted in new types of synthetic oils. For example, submitted at the 1999 Lubricants & Wax Meeting, November 11-12, Houston, Texas (National Petrochemical & Refiners Association). In a technical paper by Chevron Products Company entitled "The Synthetic Nature Of Group III Base Oils", the size of the molecule was improved in order to improve the lubrication properties of the molecule. Total hydrogen combining three catalytic processes to significantly and selectively change shape and heteroatom content Production path processing is disclosed. In order to produce an oil with excellent stability, hydrogen is added at high temperatures and pressures in all three steps. Impurities such as sulfur and nitrogen are essentially completely removed. In the manufacture of Class III, the raw material is converted to a saturate rich in isoparaffins. Reactive species such as aromatics, sulfur and nitrogen containing species are substantially eliminated, and chemical species that cause problems with low temperature performance such as linear paraffins are also eliminated. Finally, this paper provides a conclusion on the analysis of raw materials and products from commercial Class III production, where most raw material molecules produce the latest all hydrotreated Group III base oils. It has been shown to be synthetically altered by the three catalytic processes used to do this. These results show that the latest Group III base oils produced using the full hydrotreating route are artificial or synthetic in nature and compared to prior art hydrocracked base oils. And support the claim that it is advantageous. Furthermore, due to their high performance in lubricant applications, they are used in traditional composites such as polyalphaolefins (PAO) and high performance products that are often formulated. Although all hydrotreated composites are known to be classified as conventional Group III base oils, due to the synthesis process they are improved to be superior to the scope of Class III (chemical and chemical). Physically).

  The 8th Annual Annual Fuel Lubricant Asian Conference and Exhibition (The 8th Annual Fuels & Loves Asia Conference and Exhibition), January 29-February 1, 2002, Shangri-La Hotel, Singapore "Dave Kramer" entitled "Base Oil Supply / Demand And Quality Issues", Chevron Texaco Global Lubricant, "7 years by Chevron Texaco Global Lubric, 7th year" In addition, Fischer-Tropsch base oil (FTBO) should emerge as the next breakthrough in base oil quality. It must have a higher VI than O, and in all respects should be superior to PAO and existing Class III, because the Fischer-Tropsch project is driven by environmental and crude oil production incentives FTBO's volume may well exceed the demand for Class III and PAO, Kline & Company says that FTBO supply will reach 10MM MT by 2015, about the entire base oil market It ’s estimated that it will increase to 30%, ”suggesting another process.

  The Fischer-Tropsch process is a catalytic chemical reaction in which carbon monoxide and hydrogen are converted into various forms of liquid hydrocarbons. Typical catalysts used are based on iron and cobalt. The main purpose of this process is to produce synthetic petroleum substitutes for use as synthetic lubricants or synthetic fuels.

The original Fischer-Tropsch process is illustrated by the following chemical equation:
CH ₄ + 1 / 2O ₂ → 2H ₂ + CO
(2n + 1) H ₂ + nCO → C _n H _{2n + 2} + nH ₂ O
A mixture of carbon monoxide and hydrogen is called synthesis gas or syngas. The resulting hydrocarbon product is refined to produce the desired synthetic fuel. Carbon dioxide and carbon monoxide are generated by partial oxidation of coal fuel and wood fuel. Non-oxidative pyrolysis of solid materials produces synthesis gas that can be used directly as fuel without Fischer-Tropsch conversion. When fuels such as mineral oil, lubricants or waxes are needed, the Fischer-Tropsch process can be applied. Finally, when maximizing hydrogen production, a water gas shift reaction can be performed, producing only carbon dioxide and hydrogen, leaving no hydrocarbons in the production line.

  Fischer-Tropsch gas to liquid (FTGTL) is a process for converting natural gas to synthetic oil, which can then be further processed into fuel and other hydrocarbon-based products. Briefly, the FTGTL process breaks up natural gas molecules and reassembles them into longer chain molecules as if they contained crude oil. However, this special conversion process results in a very pure synthetic crude oil that is substantially free of contaminants such as sulfur, aromatics and metals. This synthetic crude oil can then be refined into products or specialty products such as diesel fuel, naphtha, wax and other liquid petroleum.

  Lubricant base oil feedstock made by gas to oil conversion is called isoparaffin. Isoparaffins currently appear to be a viable alternative for use as a base oil for lubricants blended from API Group III and IV base stocks. The main demand for Group III and Group IV base stocks is from automobile manufacturers. Lubricant performance parameters are emphasized by the additional demands placed on internal combustion engine designers for emission reduction and increased energy efficiency. High-quality base materials are essential for formulating lubricants that meet new requirements.

  Isoparaffins appear to provide the performance types necessary for internal combustion engine operating conditions including good viscosity properties (viscommetrics), oxidation resistance and cold cranking conditions at low temperatures. The development of these raw materials into useful long-term lubricants can be employed as an alternative to crude oil-derived products.

  Industrial machines often require lubricant performance in the same general temperature and oil film strength range as crankcase engine oils.

The FTGTL process is based on two main steps:
1. Conversion of natural gas to synthesis gas—In the first step, natural gas is reacted with oxygen in a process that uses a unique catalytic partial oxidation to produce a synthesis gas composed primarily of carbon monoxide and hydrogen.
2. Conversion of Syngas to Synthetic Crude Oil-In a reaction based on Fischer-Tropsch (FT) chemistry, syngas is flowed into a reactor containing its own catalyst, which converts it into a viscous liquid hydrocarbon. This process can also be produced from other raw materials such as coal and biomass. Useful catalysts for this process include, but are not limited to, those listed in the following references.
