Abstract
The invention relates to a method for producing mixed higher fatty acids by utilizing drainage oil. The method comprises the following steps: 1, carrying out coarse filtration on the drainage oil, adding a sodium hydroxide solution, slowly adding aluminum sulfate, carrying out oil-water separation, washing the obtained oil layer with soft water, carrying out oil-water separation, adding atlapulgite, carrying out hot filtration, and discarding residues to obtain refined drainage oil; 2, adding an emulsifier, a catalyst and water, stir-heating to 85-100DEG C, and reacting for 15-20h; 3, carrying out thermal maintenance standing after ending the reaction, and carrying out oil-water separation to obtain crude fatty acids and glycerin water; and 4, washing the obtained crude fatty acids with water, rectifying through a routine reduced pressure rectification device to separate the finished fatty acids with different carbon chain lengths. The method which adopts the drainage oil as a raw material fully utilizes available values of the drainage oil, solves the outlet problem of the drainage oil, and is a method which changes wastes into valuables and accords a circular economy mode. Simultaneously, the conversion rate of the fatty acids produced according to the method of the invention is high.
Description
[technical field]
The present invention relates to the lipid acid that obtains in fat, oil or the wax; The lipid acid that fat, oil or glycerin fatty acid ester therefrom obtain through chemical modification refers to a kind of method of utilizing sewer oil production mixing higher fatty acid especially.
[background technology]
Lipid acid is the basic material of oil and fat chemical, is raw material deutero-derived product with lipid acid, is widely used in all trades and professions such as weaving, daily-use chemical industry, petrochemical complex, rubber and plastic, mining, communications and transportation, metal processing.
Lipid acid mainly is through hydrolysis, the smart slide from natural fats and oils; Paraffin oxidation; From the pine papermaking wastewater, reclaiming Yatall MA makes through several methods such as essence slides., countries in the world in short supply along with petroleum resources are cut down protection and the taboo of wildwood, make to descend from paraffin oxidation with from the smart ratio that obtains lipid acid of slipping of Yatall MA, at present, have become the main source of lipid acid from natural fats and oils through hydrolysis, the smart lipid acid that makes of slipping.
Because natural fats and oils also is the main source of edible oil, the contradiction that technical oils and edible oil are contended over raw materials also becomes increasingly conspicuous.
But then; The Along with people's growth in the living standard; The surplus greasy quantity in various kitchens is also more and more, and these comprise swill oil, animal meat inferior, internal organ, skin processing and the oil that refines the back output; Grease above the wet goods behind certain number of times during fried food product uses is referred to as sewer oil, and its quantity is more and more.Some illegal retailers in addition these depleted sewer oils are collected after, through simply processing, get back to people's dining table heavily again.If edible for a long time this grease will cause great harm to the health of human body.Therefore, how reasonably handling these sewer oils will be the direction that we study.
Sewer oil is because of using; And the animal-plant oil of a series of chemical transformation such as become sour in contaminated back, oxidation and decomposition; Indexs such as its heavy metal, harmful microorganism, acid number, nitrite seriously surpass the standard of edible oil; Even therefore handle, can not be used as edible oil again through dehydration, deodorization and decolouring.But its staple remains the natural animal-plant grease, therefore, can substitute natural fats and oils fully, is used for the higher fatty acid (production of C8～C20).
[summary of the invention]
The object of the present invention is to provide a kind of method of utilizing sewer oil production mixing higher fatty acid.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of utilizing sewer oil production mixing higher fatty acid is provided, it is characterized in that comprising the steps:
One, sewer oil is carried out coarse filtration with 20～30 mesh filter screens, remove the solid swimmer;
Two, in the 100 weight parts filtrating of step 1 gained, add the 5%NaOH solution of 30～40 weight parts, be heated with stirring to 70～80 ℃, reacted 30～45 minutes; Under agitation; 10% Tai-Ace S 150,10～15 weight parts that slow adding prepares in advance continue to stir 15 minutes, and insulation was left standstill 2～3 hours; Carry out oily water separation, discard water layer and floss;
Three, with 70～80 ℃ soft water 20～30 weight parts washing oil reservoir, oily water separation, so repetitive scrubbing is 3 times;
Four, in step 3 obtains filtrating 100 weight parts, add the atlapulgite of 20～30 weight parts, and be heated with stirring to 110～120 ℃, insulated and stirred 2～3 hours is carried out heat filtering then, discards residue, obtains refining sewer oil;
Five, get sewer oil 100 weight parts of step 4 gained, add 3～5 weight part emulsifying agents, 10～20 weight part catalyzer, water 150～200 weight parts, be heated with stirring to 85～100 ℃, reacted 15～20 hours;
Six, preserving heat after reaction ends left standstill 2～3 hours, carried out oily water separation, obtained croude fatty acids and glycerol liquor;
Seven, with the croude fatty acids that obtains after washing, carry out essence slide with the smart slip device of conventional decompression, with the finished products of fatty acid of separation different carbon chain lengths.
The relevant criterion that meets higher fatty acid through the lipid acid of checking present method to make.
Emulsifying agent in present method can be X 2073, and catalyzer can be the vitriol oil.
The invention has the beneficial effects as follows: the employing sewer oil is a raw material; Having made full use of its available value, solved the problem of outlet of sewer oil, is a kind of method that turns waste into wealth, meets the recycling economy pattern; Simultaneously; Because sewer oil has had new purposes, greatly reduces the possibility that flows back to dining table, has good social benefit.
Sewer oil was the thing that goes out of use originally, and cost of material is significantly less than natural finished product grease, with its manufacture higher fatty acid, can significantly reduce production costs, and had considerable economic.
The conversion rate of fatty acid of producing by the inventive method is high.
