The biomass truck lubricating oil prepared by adopting the method has high biodegradability, is green and environment-friendly lubricating oil, and is simple in technique and low in cost.
Description
Technical field
The present invention relates to the lubricating oil preparation field, specifically a kind of preparation method of biomass truck lubricating oil.
Background technology
Lubricating oil is one of four large petroleum productss, is the important goods that involves the interests of the state and the people.At present, China is the second-biggest-in-the-world lubricating oil country of consumption that is only second to the U.S., and increase year by year, these lubricating oil derive from oil more than 95%, but oil is a kind of non-renewable rare energy, and the biological degradability of mineral lubricating oils is relatively poor, is lost in environment and can causes huge harm to the ecosystem.Therefore, development and exploitation have the environmentally friendly lubricant base of renewable resources, are significant.
The discarded food oils (sewer oil) in meal kitchen have viscosity-temperature characteristic and good lubricity preferably later through the special process processing treatment, has recyclability, nontoxic, free from environmental pollution, but owing to containing a large amount of two keys in its molecular structure, its range of application and work-ing life have been limited.
Summary of the invention
The invention provides a kind of preparation method of biomass truck lubricating oil, solve the environmental issue of existing lubricating oil.
The technical scheme that the preparation method of this biomass truck lubricating oil of the present invention adopts is: comprise the steps:
A, stock oil pre-treatment: the discarded food oils in the kitchen of eating carry out flash-evaporation dehydration, remove impurity;
B, esterification: the stock oil that pre-treatment is good adds methyl alcohol, and acid catalyst is warming up to 65 ℃～75 ℃ reactions, and reaction 2h～4h reclaims excessive methanol, removes the water of acid catalyst and generation, makes acid number≤2mgKOH/g;
C, transesterification reaction: the grease after esterification and ester are added methyl alcohol, and alkaline catalysts is warming up to 65 ℃～75 ℃ reactions, and reaction 0.5h～1h reclaims excessive methanol, obtains thick methyl esters after separation of glycerin;
D, slightly methyl ester distilled: thick methyl esters is sent into to distill in distillation tower make with extra care, obtain smart methyl esters;
E, epoxidation reaction: the smart methyl esters after distilling, hydrogen peroxide, formic acid add in reactor by weight 100: 30～50: 5～15, open and stir, when being heated to 40 ℃ of left and right, beginning slowly drips hydrogen peroxide, keeps rate of addition even, dropwise in 2h～3h, when dripping hydrogen peroxide, temperature should be controlled at 55 ℃～60 ℃, and after hydrogen peroxide dropwised, temperature of reaction should be controlled at 60 ℃ of left and right, insulation 6h～8h, the ester that obtains after reaction are epoxy aliphatic acid methyl ester mutually;
F, add additive: extreme-pressure anti-friction additive, pour point depressant are in harmonious proportion in epoxy aliphatic acid methyl ester, namely get biomass truck lubricating oil.
The preparation method of this biomass truck lubricating oil provided by the invention, by the epoxidation novel process, its unsaturated double-bond is reached capacity, improve its oxidation-stabilized performance, can prepare have high biodegradability, environmentally friendly lubricating oil, and technique is simple, environmental protection, cost are low.
