Description
Technical fieldThe present invention relates to the method for production machinery lubricating oil, belong to technical field of lubricating oil.
Background technologyRosin mainly is made up of resinous acid and terpene hydrocarbon, contains small amount of impurities and moisture in addition.The content of resinous acid and terpene hydrocarbon is different because of seeds, the place of production, resin tapping method and storage period.Pinus massoniana Lamb rosin generally contains resinous acid and about 20% the terpene hydrocarbon about 75%, and all the other are moisture and impurity.Resinous acid has two types in the rosin: 1. abietic-type acid, comprise abietic acid, levopimaric acid, palustric acid, neoabietic acid, dehydrogenation abietic acid, and be the major portion in the resinous acid.2. pimaric-type acid comprises pimaric acid, isopimaric acid.Contain more levopimaric acid in the Pinus massoniana Lamb rosin, but the isomery that in the course of processing, is heated becomes other abietic-type acids, so be substantially free of levopimaric acid in the rosin, and contain other more abietic-type acids, particularly abietic acid.Pinus finlaysoniana rosin contains dicarboxyl resinous acid.Terpene hydrocarbon in the rosin mainly is a-firpene and beta-pinene.Both content change bigger with seeds and area etc.Also have β-phellandrene, amphene, myrcene, kautschin, longifolene, caryophyllene etc. in addition.In homemade rosin to contain carene very few.Rosin factory will isolate residue from the rosin that pine tree collects dissolution process, the pure rosin of 2 0-400/6 is also contained in the inside except that some barks, wood chip are arranged; Adding that some were stacked has little time to handle and dry rosin for a long time; The broken rosin that packing shop is scattered, inferior rosin etc., past; Processing to these waste residues, substandard products generally is its simple cracking to be obtained cracked oil make fuel for other factory; What have then abandons it, and this has not only wasted valuable natural resources, returns environment and has caused pollution.So,, be still the problem that many woods chemists are exploring at present how with the further comprehensive development and utilization of rosin waste residue.
Summary of the inventionThe purpose of this invention is to provide a kind of method that is fit to the machine oil that multiple machine such as lathe, automobile, agricultural machinery and implement and mechanical device instrument use of from the rosin waste residue, producing through cracking.
Another object of the present invention is the useful resources that makes full use of the Nature, for a new road is opened up in utilization of waste material, and can alleviate the environmental pollution that waste sludge discharge causes.
Realize that method of the present invention is earlier the rosin waste residue to be distilled at a lower temperature, isolates moisture content and light oil (light oil comprises a small amount of turps, is used for incendiary lower boiling rosin oil); Add catalyzer then; Under comparatively high temps, make the rosin cracking, the fraction of specified temp is collected in distillation in cracking process, as the base oil of machine oil; Remove imperfect knob branch with acid-base method or solvent method, absorption method then; Be in harmonious proportion base oil again, and in mediation, add oxidation inhibitor, dispersion agent, pour point depressant etc., just obtain the machine oil of different model.
Generally contain pure rosin 20-40% in the rosin waste residue; The main chemical of rosin is the high-molecular weight hydrocarbon polymer; Various kinds of resin acid is wherein arranged like abietic acid, levopimaric acid, palustric acid etc., cracking process generally are that the high-molecular weight hydrocarbon polymer is cracked into low-molecular-weight hydrocarbon polymer; Resinous acid carries out decarboxylic reaction, and its principal reaction formula is following:
Cracking rosin removes decarboxylate, also contains following compounds, cyclolefen 5-9%, aromatic hydrocarbon 8-12%, pseudocumol 1-3%, polynuclear aromatics 20-25%.
Cracking temperature of the present invention is chosen between 160-500 ℃, but the component proportion of distillation gained is lighter between 160-180 ℃, the general oil that acts as a fuel of collecting, and collected is the fraction between 180-400 ℃, as the base oil of machine oil.
Below describe working method of the present invention in detail.
One, cracking
Quantitative rosin waste residue is put into cracking still, be warming up to 135-150 ℃ earlier, open water coolant at the water cooler on still top; Steam light oil (comprising turps and oil fuel) and water, the amount of pressing leftover materials again adds the catalyzer of 2-4%, under 160 ℃-500 ℃ temperature cracking 9-10 hour; Through condenser condenses; Isolate component below the 180 ℃ oil that acts as a fuel, the cracked oil of collecting 185-395 ℃ is as the base oil of machine oil, and the catalyzer of being selected for use adopts oxide compound or acidic substance; Like Vanadium Pentoxide in FLAKES, zinc chloride or acidic white earth, the carclazyte of acidic white earth for soaking with hydrochloric acid, phosphoric acid, boric acid.
Two, refining
Collect the compound that obtains after the cracking and remove the nytron beyond the region of objective existence that contains required machine oil, also have materials such as cyclolefen, pseudocumol, aromatic hydrocarbon, polynuclear aromatics such as benzene, naphthalene, anthracene, colloid, these are undesirable components of lubricating oil; Must remove just and can obtain colory lube product; It is refining that the crack goes the process of undesirable components to be called, and the method for removing undesirable components can adopt three kinds, and the one, the acid-alkali treatment method; The 2nd, organic solvent method, the 3rd, absorption method.The acid-alkali treatment method is to be put into earlier in the cracking gained compound with hydrochloric acid or phosphoric acid, formic acid, propionic acid etc., and earlier that proportion is the bigger acid layer in thorough mixing contact back separates, and after adding caustic soda or soda ash, unslaked lime again and making pH reach neutrality, dephlegmate part gets final product then.Organic solvent method is that benzene, acetone or alcohol are added in the compound after the cracking, and fully the contact back steams organic solvent with distillation method.Absorption method is that zeyssatite, atlapulgite, molecular sieve or other polar material are added in the compound after the cracking, fully contacts the postprecipitation press filtration.
Three, be in harmonious proportion
The cracked oil made from extra care out can't directly become product to be used mechanically; Must be according to requirements such as the physicals of variant prodn such as viscosity, flash-point, zero pour, acid numbers; Add an amount of additive; So that obtain qualified lubricating oil, the additive that the present invention added mainly contains oxidation inhibitor such as T201 (alkylphenol sulphur phosphorus zinc salt), T202 (isopropylcarbinol sulphur phosphorus zinc salt), detergent-dispersant additive such as T105; (alkylphenol barium), T102 (mahogany acid
Calcium), T109 (alkyl sodium salicylate), pour point depressant such as T801 (alkylnaphthalene), T803 (2-alkene copolymer) etc.Advantage with rosin waste residue production machinery lubricating oil is:
1. can make full use of the useful resources of the Nature; Particularly continually developing of oil and coal resources petered out natural resource, but people can be through the plantation pine tree; Produce machine oil and replace the part petroleum oil, the chemistry of forest product raw material will be following important chemical feedstocks.So the development and use of rosin waste residue have crucial meaning.
2. alleviated environmental pollution, because the rosin waste residue directly discharges, polluted the soil, hindered plant-growth, the polluted water resource has been destroyed the eubiosis of the Nature.
3. when obtaining machine oil with the production of rosin waste residue; Can also obtain part turps and oil fuel; General per 6 tons of rosin waste residues cracking can obtain 0.9 ton of base oil; 1 ton of light oil (comprising turps and oil fuel), the cost of producing 1 ton of lubricating oil is identical basically with the lubricating oil of from oil, producing.
4. the cracking of rosin waste residue is after refining, and the machine oil that mediation obtains is identical with the machine oil physicochemical property from petroleum refining, and result of use is also identical.
5. production technique is simple, and equipment is uncomplicated, easily operation.
