Technical Field

The invention relates to a formula for improving the wear resistance of diesel by utilizing biodiesel, in particular to a method for using the biodiesel as an anti-wear agent or replacing a fatty acid ester type anti-wear agent, solving the problems of diesel emulsification and filter element blockage caused by the fatty acid ester type anti-wear agent, or replacing the fatty acid type anti-wear agent, being used in high-acid-value diesel, preventing the acid value of a diesel product from exceeding the standard, or using the biodiesel and the fatty acid ester type anti-wear agent or compounding the biodiesel and the fatty acid type anti-wear agent, reducing the blending cost of the diesel, increasing the additional value of the biodiesel and improving the economic benefit.

Background

With the increasing strictness of environmental requirements, the upgrading speed of the quality of the vehicle diesel oil is accelerated, the vehicle emission standard is improved, the contents of components such as sulfur, polycyclic aromatic hydrocarbon and the like are strictly regulated in the five national standards of the vehicle diesel oil in China, but the lubricating property of the low-sulfur low-aromatic diesel oil is poor, and a lubricity improver is required to be added into the upgraded vehicle diesel oil to improve the lubricating property of the diesel oil.

Diesel engine wear is primarily due to adhesive wear and fretting wear. The adhesive wear is the main wear mode of the fuel pump, and an anti-adhesion lubricity improver can be added to increase the thickness of a protective oil film and reduce the adhesive wear of the fuel pump. The diesel antiwear agent improves the lubricating performance of diesel oil mainly through the adsorption of surface active molecules on the surface of friction metal. The two top ends of the antiwear agent molecules are respectively provided with a polar group and a nonpolar group, after encountering metal, the polar group of the molecules is adsorbed to the metal surface to form an oil film, and the nonpolar group at the other end enters the diesel oil, so that the antiwear agent can provide boundary lubrication between the metal surfaces, form a protective layer on the metal surfaces, effectively prevent the metal surfaces which are rubbed by relative motion from directly contacting, and further effectively reduce mechanical wear.

Common diesel antiwear agents currently used in production include alcohols and ethers, fatty amines and amides, and fatty acids and fatty acid esters.

Alcohol and ether compounds have higher polarity because of molecules, the lubricity of the low-sulfur diesel oil can be remarkably improved when the alcohol and ether compounds are added into the low-sulfur diesel oil, but the required dosage is larger to meet the national standard requirements, and a large amount of additives can change some physicochemical properties of the diesel oil and do not meet the addition standard of the additives. The fatty amine and the amide antiwear agent can effectively improve the lubricating property of diesel oil, but the substances are nitrogen-containing compounds, and when the concentration is too high, the emission of tail gas pollutants can be increased. The fatty amine and amide compounds are mostly synthesized from fatty acid and polyamine compounds, have higher acid value, have corrosion effect on diesel engines, and are easy to generate insoluble particulate matters by reacting with alkaline substances in lubricating oil, thereby increasing the abrasion of cylinders. At present, the diesel antiwear agent mainly comprises two products of fatty acids and fatty acid esters.

Unsaturated fatty acid of C16-C18 is an effective component of the antiwear agent, and saturated fatty acid such as stearic acid and abietic acid, metal elements such as sodium, magnesium, calcium, zinc and iron, and nonmetal elements such as phosphorus, boron, silicon and chlorine are non-ideal components of the antiwear agent and need strict control. The acid type antiwear agent has a high acid value (185-210 mgKOH/g), the acidity (KOH) of diesel oil can be increased by 3.2-3.6 mg/100mL according to the addition of 200mg/kg, and the condensation point of the acid type antiwear agent is higher than that of the ester type antiwear agent, so that the fatty acid type antiwear agent is only suitable for low-acidity diesel oil, and the excessive acidity of the diesel oil can be caused by adding the acid type antiwear agent into high-acidity diesel oil.

The fatty acid ester type antiwear agent is prepared with long chain unsaturated fatty acid and glycerin and other polyol as material and through esterification reaction in the presence of catalyst to produce fatty acid polyol monoester. The 'fine petrochemical product' reported in 6.2006 examines the carbon chain length of fatty acid and the influence of polyol, polyene polyamine, alcohol amine and the like which react with the fatty acid on the additive effect, and the results show that the antiwear agent effect is enhanced along with the increase of the carbon chain of the fatty acid, the effect of oleic acid, linoleic acid and ricinoleic acid is better than that of stearic acid in the fatty acid with the carbon number of 18, the preferred polyol is propylene glycol, the acid value of the product is 2.5-5.0 KOH mg/g, and when the additive mass fraction of the antiwear agent is more than 300mg/g, the requirement of the diesel oil for vehicles on lubricity can be met, but the acid value is higher, the additive amount is large, and the diesel oil blending cost is increased. The reports of comprehensive utilization of oil in 5 months in 2015, wherein 4 long-chain-ester polyol monoester fatty acid ester antiwear agents are synthesized by reacting glycol, 1, 3-propanediol, glycerol, 1, 3-butanediol, pentaerythritol and cottonseed oil biodiesel in the petrochemical engineering research institute, such as blush, and the like, meet the technical requirements of fatty acid ester antiwear agents, but the polyol monoester fatty acid ester antiwear agents simultaneously have hydrophilic lipophilic groups and belong to surfactants, so that emulsification is easy to occur in use, remaining metal ions and unsaturated fatty acids are easy to form saponification products such as sodium fatty acid and the like, and the filterability of diesel oil is influencedCan cause the problem of filter clogging, and the acid (H) used in the preparation of the product is washed, neutralized and rectified₂SO₄) Or an alkali (NaOH) catalyst is removed, so that the residual metal ions and unsaturated fatty acid are prevented from forming saponified substances such as sodium fatty acid and the like, and the cost of the fatty acid ester type antiwear agent is relatively high.

The biodiesel refers to Fatty Acid Methyl Ester (FAME) obtained by transesterification of oil crops such as soybean, rape, cotton and palm, aquatic plant oil such as wild oil plants and engineering microalgae, animal oil and food waste oil, and glycerin as a byproduct. The catalytic methods used for transesterification are mainly: chemical methods (alkali catalysis method and acid catalysis method), biological enzyme methods and supercritical methods, and the preparation method of the industrial biodiesel mainly comprises the chemical method and the biological enzyme method.

The biodiesel is mainly used for blending vehicle diesel and fine chemical application. The blended vehicle diesel comprises B5 biodiesel, B10 biodiesel and B20 biodiesel, and is mainly B5 biodiesel at present in China. However, the price of the biodiesel is lower than that of the diesel, the benefit is influenced, the temperature is low in winter in the north, and the biodiesel cannot be used in winter, so that the popularization and the application of the biodiesel are not satisfactory except that the biodiesel is well popularized and applied due to the fact that the policy is supported in place in the Shanghai. The biodiesel also needs to find a way with high added value and relatively simple and convenient application method.

The biodiesel oil has better polarity due to oxygen atoms, can be adsorbed on a friction surface to form a protective film to play a better lubricating role, has no hydrophilic hydroxyl group compared with a polyol monoester type antiwear agent, is not easy to emulsify during use, is low in metal ion content, meets the requirement that the metal mass fraction of the antiwear agent is less than or equal to 50 mu g/g, does not block a filter, has higher unsaturated fatty acid methyl ester, and meets the requirement that the acid value of the ester type antiwear agent is less than 1 mgKOH/g.

According to the application, the biodiesel is used as an anti-wear agent, or the polyol monoester fatty acid ester anti-wear agent is replaced, the problems of diesel emulsification and filter element blockage caused by the fatty acid ester anti-wear agent are solved, or the fatty acid type anti-wear agent is replaced, the biodiesel is used for high-acid-value diesel, the acid value of a diesel product is prevented from exceeding the standard, or the biodiesel and the fatty acid ester anti-wear agent or the fatty acid type anti-wear agent are compounded for use, the diesel blending cost is reduced, the additional value of the biodiesel is increased, and the economic benefit is improved.
