Abstract
The invention relates to an oil product decolorizing agent which is composed of sulfuric acid (with a concentration no lower than 98%), anhydrous ethanol, and oleic acid. According to the invention, preparation is operated under normal temperature and normal pressure according to a certain ratio and a certain sequence. The decolorizing agent has the advantages of no three-waste pollution, low cost, easy-to-purchase raw materials, simple process, and convenient application. With the decolorizing agent, oxidized black diesel oil produced during catalytic cracking coking and waste oil and waste rubber oil refining can be decolorized, and a chromaticity can reach a national standard.
Description
Technical field
The present invention relates to a kind of oil product discoloring agent, belong to petrochemicals.
Background technology
At present, because the diesel oil that middle-size and small-size refinery is produced through methods such as catalytic cracking coking, contain a large amount of sulphur, nitrogen, the heterogeneous ring compound of oxygen, olefin(e) compound and aldehydes matter, make the poor stability of diesel oil, place after several days, that have even be variable color in one day, muddy, and produce a large amount of colloids and sediment, non-hydrocarbons is nonbasic oxide particularly, such as pyroles, the character such as four oxygen carbazoles are very unstable, easily are oxidized to superoxide and cause hydrocarbon oxidation, and quinoline beautiful jade class has the oxidation catalysis effect when nonbasic oxide coexists, can generate and hydrocarbon oxidation by the accelerated oxidation thing, above-mentioned these reactions not only make the color and luster of diesel oil deepen, and affect the use value of oil product, and also can supervene the insoluble gluey settling of a large amount of black in oil product, cause the obstruction of oil supply line, affect normal fuel injection, this fuel combustion thing forms carbon distribution at engine nozzle, and the aggravation engine scuffing also causes spray nozzle clogging.
The method that prior art solves oxidation blackening diesel decoloration is to adopt to add industrial sulphuric acid and stir, behind the reaction precipitation, add again the sodium hydroxide neutralization or add atlapulgite absorption, but these techniques decolourings complicated, slag tap many, stationary phase is short, easy reduction.Present published CN1058038A, CN1279269A only can process catalytic diesel oil, and can not process other diesel oil such as coker gas oil, thermally splitting diesel oil and the finished diesel fuel that contains more oxidation insolubles and colloid.These published patented methods are not enough: 1. only adapt to catalytic diesel oil, to coker gas oil, washing oil, thermally splitting diesel oil, the black diesel oil of used oil, waste rubber oil refining time institute's oxidation is invalid.2. decoloration process is complicated, and addition is large, and cost is high.3. slag tap many, reach 5～10%, unstable, easily reduction.So in fact above-mentioned patent can not be applied.According to this phenomenon, in person field trip, through for many years with great concentration development, developed a kind of new oil product discoloring agent, combine with sanitising agent sulfuric acid (content 〉=98%), solubility promoter dehydrated alcohol, properties-correcting agent oleic acid, applied widely, the black diesel oil that adapts to catalytic thermal cracking coker gas oil, washing oil and damaged tire, waste rubber, used oil oil refining time institute's oxidation all adapts to, easy to operate, consumption is little, slag yield is low, stationary phase is long, do not reduce, as clear as crystal.
Summary of the invention
Purpose of the present invention just provides and a kind ofly overcomes weak point of the prior art, and provides a kind of Recipe simple, can operate at normal temperatures and pressures, does not have the oil product discoloring agent that pollutes.Its characteristics: technique is simple, easy to use, and consumption is little, cost is low, raw material is easily purchased wide accommodation.
Oil product discoloring agent of the present invention is comprised of sanitising agent sulfuric acid (content 〉=98%), solubility promoter dehydrated alcohol, properties-correcting agent oleic acid, produces efficient diesel decoloring agent by stirring at normal temperatures and pressures.
Content of the present invention is a kind of oil product discoloring agent, and purpose of the present invention can be finished in the following manner.
The component proportioning of oil product discoloring agent of the present invention is weight percentage:
Sulfuric acid (〉=98%) 60～75%
Dehydrated alcohol 20～30%
Oleic acid 5～15%
The component proportioning of oil product discoloring agent of the present invention can also be weight percentage:
Sulfuric acid (〉=98%) 65～70%
Dehydrated alcohol 22～26%
Oleic acid 4～12%
Compound method of the present invention be with above-mentioned various raw materials by proportioning, be sequentially added into and stir 5～15 minutes in the container, namely can be made into the oil product discoloring agent.
Oil product discoloring agent of the present invention is through practical application in recent years, in Chengdu, ground 20 many enterprises such as Dongguan, Puyang, Maoming have used its characteristics of proof, reach its application target (consumption proportion: black diesel oil 98%, discoloring agent 2%).
First: oil loss is few, and smell is pure, its slag yield≤2%, and colourity reaches GB, grows stationary phase, does not reduce, as clear as crystal.
Second: applied widely, the black diesel oil that adapts to catalytic thermal cracking coker gas oil, washing oil and damaged tire, waste rubber, used oil oil refining time institute's oxidation all adapts to.
The 3rd: cost is low, consumption is little, few worker, save time, laborsaving, convenient to operation.
The 4th: solved the difficult problem of processing of waste, the waste residue with this agent washes out, do not lump, non-caked, do not solidify, but utilization of waste material has solved environmental issue.
Embodiment
Embodiment 1
Sulfuric acid (〉=98%) 66%
Dehydrated alcohol 26%
Oleic acid 8%
Embodiment 2
Sulfuric acid (〉=98%) 68%
Dehydrated alcohol 22%
Oleic acid 10%
Operating process and the condition of above two kinds of embodiment are identical, and both at normal temperatures and pressures operation was selected in the rear adding stirred vessel by any embodiment, stirred 5～15 minutes, can obtain the oil product discoloring agent.
The coker gas oil that one refinery is produced in the Puyang, i.e. the diesel oil of already oxidised mistake (black diesel oil), the discoloring agent that adopts the embodiment of the invention 1 to provide, adding dosage is 2%, and normal temperature and pressure stirring reaction 2 hours is emitted sediment, and slag yield only is 2%.Press ASTM D1500 standard testing colourity, the result is 2.0, and colourity namely reaches GB.
Subordinate list (colourity is pressed ASTM D1500 standard testing)
| Date | June 1 | June 11 | June 21 | July 1 | July 11 | July 21 |
| Project | Colourity | Colourity | Colourity | Colourity | Colourity | Colourity |
| Blank oil | 2.0 | 3.4 | 4.0 | 4.5 | 5.0 | ＜6.0 |
| Embodiment 1 | 2.0 | 2.0 | 2.0 | 2.0 | 2.0 | ＜2.0 |
As can be seen from the table, added the coker gas oil of this agent, the effect of reached nondiscoloration, not reducing.
