Description
Invention field
The invention belongs to the processing category of animal-plant oil, relate in particular to the preparation method of the refining oil of the raw plant oil, waste grease and the algae grease that squeeze or extract.
Background technology
Be accompanied by the development of world economy, the increase day by day of petroleum resources consumption, energy shortage has become the significant problem that affects the human society sustainable development.For national energy security is considered, renewable energy source is competitively sought to alleviate the nervous problem of oil in countries in the world.Bioenergy is because reserves are abundant, and there are environmental friendliness and reproducible characteristics, when meeting the Future Society energy demand, the theory that also meets the sustainable Scientific Outlook on Development and recycling economy, therefore exploitation and use bioenergy have become the important component part of world today developed country energy strategy.
Yet, process Raw in the biological boat of preparation coal/biofuel accounts for more than 60% of total cost, and therefore the supply of how acquisition scale, cheapness, the oil resource that can be used as energy purposes are core and the key issues that biological boat coal/Biodieselization must solve.Suitable raw material production biofuel is selected according to national conditions one after another in countries in the world at present, as the U.S. mainly utilizes the high-yield transgenic soybean, prepares biofuel; European Countries implant mass rape, utilize rapeseed oil production biofuel; Southeast Asian countries utilizes plam oil as the production of biodiesel raw material; Japan mainly adopts waste cooking oil to produce next life such as thing diesel oil etc.And China is vast in territory, available Vegetable oil lipoprotein is a lot, and wherein the herbaceous plant such as vegetable seed, soybean is current artificial growth class farm crop the most widely.But, because China is populous, the herbaceous plant grease yield still can not meet the market requirement of edible oil, therefore can not be by food oils for the scale operation biofuel.And the traditional oil tree fruits such as the little seeds of a tung oil tree, Wood of Shinyleaf Yellowhorn, wilson dogwood, Chinese pistache have that oleaginousness is high, wide accommodation, the drought-resistant characteristics such as barren, can be in mountain region, plateau, even sand ground plantation of knob, not only meet the development principle that China's biomass energy " is not striven grain with the people; with grain, do not strive ground ", and to improving the ecological environment, transform agricultural production, promote rural economic development, all tools such as increase farmers' income are of great significance.Simultaneously, China is as an edible oil consumption big country, the waste grease total amount that the approach such as annual foodstuff production, changing food waste produce reaches more than 6,500,000 tons, through further processing, the raw material that can become biological boat coal/biofuel is used, production cost that so not only can the decrease biofuel, and, to the rational utilization of waste grease, prevent that waste grease from again entering food chain and promoting that the development of biological boat coal/biofuel is all very favourable.
The oleaginousness of woody oleiferous plants seed is higher, and the grease that usually adopts mechanical expression or solvent extraction mode to produce is referred to as crude oil.It in the animals and plants crude oil, more than 95%, is triglyceride level, also have in addition the impurity such as a certain amount of free fatty acids, phosphatide, metal, pigment, sulfide, nitride, these impurity have very large impact to technique, catalyzer and the quality product of the biological boat of hydrogenation method preparation coal/biofuel.Therefore, no matter which kind of oil resource, all must can meet the requirement of biological boat coal/biodiesel processes to raw material through refining.
Chemical refining is a kind of traditional vegetable oil fine smelting method, generally comprises operations such as coming unstuck, neutralize (alkali refining), decolouring, deodorization.Come unstuck is mainly to remove the impurity such as phosphatide, protein and sugar fat; Neutralization be by alkali and grease in free fatty acids; Decolouring is the unsaponifiables such as pigment that utilize in the absorb oils such as carclazyte; Deodorization is that the method for wet distillation is removed the trace impurity in degrease.As in patent CN1147009A, CN1749380A, CN104021A, CN1147011A open with coming unstuck, the method for the chemical refinings such as neutralization carrys out the grease of production different standards.The operation of chemical refining is many, operational path long, energy consumption is also large.Neutralization (alkali refining) simultaneously not only can cause free fatty acids loss, and the Chinese honey locust produced can carry 20～50% triglyceride level secretly, causes the refining rate of loss to increase.Due to needs laundry soap compound, therefore also can produce waste water in addition, the COD value of these waste water is higher, difficult treatment.Although equipment and process is updated in recent years, but the chemical refining principle never changes over nearly 70 years, and adopt chemical refining technique to carry out the refining animal-plant oil, resulting refining oil can not reach the raw material index request (phosphorus content be less than 3ug/g, metal be less than 5ug/g, unsaponifiables be less than 0.5% etc.) of the biological boat of hydrogenation method preparation coal/biofuel fully.Therefore, can adopt a kind of raw oil refining technique, when removing the impurity such as phosphatide, metal, pigment, the free fatty acids in losing grease not, and meet the raw material index request of the biological boat of hydrogenation method preparation coal/biofuel, become the task of top priority of oil and fat refining industry.
Summary of the invention
The object of the present invention is to provide a kind of preparation method who is applicable to the non-edible crude oil refining oil of the biological boat of hydrogenation method preparation coal/biodiesel raw material requirement, utilize the method can remove efficiently the impurity such as phosphatide in different quality crude oils, metal, pigment and keep the acid number in grease constant.Little, the non-wastewater discharge of refining process grease loss simultaneously.
Preparation method's process of non-edible crude oil refining oil of the present invention is as follows.
(1) crude oil that will squeeze or extract filters, and removes solid particle polluter wherein, then is heated to 40～80 ℃;
(2) under the agitation condition of 100～1000 rev/mins, add respectively conversion-complexing agent that quality is crude oil 1～3%, constant temperature stirs 50～90min.Adopt centrifugation after reaction finishes, obtain degummed oil and You Jiao;
(3) degummed oil dewaters under vacuum tightness 0.07～0.09MPa, 95～105 ℃ of temperature, time 15～25min condition, removes the minor amount of water in grease;
(4) under the condition stirred, the grease after dehydration is heated to 90～110 ℃, then add 1～4% sorbent material, constant temperature stirs 10～30min, filters and obtains refining oil.
The crude oil used in above-mentioned refining process is one or more in the little seeds of a tung oil tree, Chinese pistache, Wood of Shinyleaf Yellowhorn, wilson dogwood, Aleurites montana, sea-buckthorn, oil tea, tung oil tree, Chinese tallow tree, sewer oil, butter, sheep oil, lard.
Conversion-complexing agent is one or more in hydrochloric acid, carbonic acid, phosphoric acid, sulfuric acid, citric acid, formic acid, oxalic acid, tartrate, maleic acid, diacetyl oxide, water.
Sorbent material is one or more in silica gel, gac, diatomite, silicon-dioxide, acidic white earth, ion exchange resin, carbon fiber, carbonaceous molecular sieve, active calcium oxide.
The present invention is applicable to the crude oil of different qualities, different acid numbers, and in the course of processing, the acid number in the maintenance grease is constant, thereby has reduced loss, has improved the refining yield; Omit washing and deodorising process simultaneously, therefore simplified the refinery practice flow process, reduced energy consumption and non-wastewater discharge, greatly saved production cost.Refining efficiency of the present invention and stability are high, can carry out large-scale operate continuously.
Gained refining oil quality reaches the raw material index request (phosphorus be less than 3ug/g, metal be less than 5ug/g, unsaponifiables be less than 0.5% etc.) of the biological boat of hydrogenation method preparation coal/biofuel fully.
