Description
Technical field
The present invention relates to a kind of handling process of softening oil, belongs to chemical products field, product is mainly used in rubber system
In the industries such as product such as tire.
Background technology
Residual oil or heavy oil are the remaining mink cell focuses after crude oil extracts gasoline, diesel oil, and its elementary cell is low molecular monocyclic
Aromatic hydrocarbons, polycyclic aromatic hydrocarbon (polycyclic aromatic hydrocarbons, abbreviation PAHs) and polycyclic aromatic hydrocarbon.And 4-6
The polycyclic aromatic hydrocarbon of ring has strong carcinogenecity, and most representational is 3,4- benzopyrene (BaP).Its mechanism of carcinogenesis is multi-ring
Aromatic hydrocarbon enters internal, generates various intermediate products and end-product with function oxidase metabolism, and some of them metabolite can be with
DNA covalent bond forms PAH-DNA adducts, causes DNA damage, induced gene mutation, or even induced tumor to be formed.For this purpose,
The western countries such as Germany and Poland have had been switched off most of softening oil processing factories, while specifying to soften polycyclic aromatic hydrocarbon in oil product
Content is less than 50mg/kg, which limits application of the oil product in many fields, and China is also in developing country, rubber
It is also quite big to the dependence of rubber softening oil and demand in field, polycyclic aromatic hydrocarbon content in oil product how is effectively reduced, is subtracted
Few environmental pollution becomes the important topic of current research.
The method for reducing polycyclic aromatic hydrocarbon in the softening oil product such as residual oil or heavy oil at present mainly has Ozonation, vacuum distilling
Method, ultraviolet irradiation, low boiling point solvent extract method and chemic modified method etc., most economical most convenient is most expected in these methods
Realize that industrialized is exactly chemical modification, according to similar compatibility principle, the cross-linking agent of selection should be dissolved each other with polycyclic aromatic hydrocarbon in oil product,
Contain active group simultaneously (such as electron-donating group).
Chemic modified method generally using the cross-linking agent such as Polyethylene Glycol, polystyrene, furan resin, paraformaldehyde and heavy oil or
Polycyclic aromatic hydrocarbon reaction (PAHs) in residual oil, generates condensation polycyclic aromatic hydrocarbon resin.But, heavy oil or residual oil composition are more multiple
It is miscellaneous, along with polycyclic aromatic hydrocarbon reactivity differs, and cross-linking agent factor such as dissolubility in oil product so that the extent of reaction
It is low, the detoxification treatment effect on driving birds is not good of polycyclic aromatic hydrocarbon (PAHs).
Based on previous karyotype studies, present invention seek to address that chemic modified method polycyclic aromatic hydrocarbon (PAHs) detoxification treatment is low,
The extent of reaction is low, and gained softening oil is because the problems such as in mixed process, heterogeneity causes poor-performing.The present invention is proposed using micro-
Channel reactor as reaction vessel, to solving the above problems.Micro passage reaction is size between 10 to 300 microns
A kind of duct type microreactor of continuous flowing, microreactor have great specific surface area, up to stirred tank specific surface area
Even thousands of times of hundred times, the basic advantage thus brought is great heat exchange efficiency and mixing efficiency, can be anti-with precise control
Answer temperature and reaction mass instantaneously to mix by accurate proportioning, greatly improve reaction efficiency.Exactly these features so that in microchannel
Reactor serves good effect in terms of polycyclic aromatic hydrocarbon (PAHs) detoxification is processed, and greatly improves the extent of reaction, so as to have
Effect solves the problems such as detoxification efficiency is low, and the extent of reaction is low, oil product mixes heterogeneity.
The content of the invention
The present invention relates to a kind of handling process of softening oil, its preparation method is comprised the following steps：After taking Petroleum refining
Byproduct residual oil or heavy oil, add the catalyst of the 5-50% cross-linking agent and raw material oil quality 1-10% of raw material oil quality, in nitrogen
Under the conditions of gas shielded, 70-200 DEG C is heated to, is stirred, after milled processed, Jing mass flow pumps squeeze into micro passage reaction
In, 70-200 DEG C is heated to, 0.5-6h is processed, modified oil product is obtained.Method equipment requirements involved in the present invention are simple, oil product
Rapidly and efficiently, gained oil product is a kind of softening agent of function admirable to handling process, and in oil product, polycyclic aromatic content is low, product ring
Border close friend is pollution-free, applies in rubber, can effectively improve glue bond, with preferable economic benefit.
Byproduct residual oil or heavy oil that described raw oil is selected after taking Petroleum refining.Can be subdivided into according to viscosity and density
The mixing of high viscosity, low-viscosity, big density, little density oil product or above-mentioned four kinds of oil products.
Described cross-linking agent, it is characterised in that：Cross-linking agent selects Polyethylene Glycol, polystyrene, furane resins, polyethylene tree
The derivant of fat, 5 resin of carbon, aldehydes, aromatic alcohol, aromatic aldehydes and above compound, or the mixing of above-mentioned cross-linking agent.

The Bronsted acids such as acid；Or it is sour from Lewis such as boron chloride, aluminum chlorides, or the mixing of above-mentioned catalyst.
Described micro passage reaction, it is characterised in that：Micro passage reaction is -100～400 DEG C using temperature range,
Pipe diameter is 10～1000 microns.
Containing the polycyclic aromatic hydrocarbon that concentration is higher in oil product selected by the present invention, usual content in 35-55%, in order to process
Fall the polycyclic aromatic hydrocarbon in oil product, obtain a kind of environmentally friendly, of good performance rubber softening oil, add Polyethylene Glycol, paraformaldehyde
Deng polymer as chemical modification cross-linking agent, it is heated to be condensed to yield condensation polycyclic aromatic hydrocarbon resin, change many in oil product
Aromatic hydrocarbon ring structure, reduces which to environmental hazard toxicity, while during using as rubber softening oil, Ji Nengti
For bating effect, can play a part of again to improve sizing material autohension.
The reactor that the present invention is adopted is different from traditional heated and stirred kettle, but selects more several than stirred tank specific surface area
The micro passage reaction that even thousands of times of Radix Achyranthis Bidentatae, its great heat exchange efficiency and mixing efficiency, can be with precise control reaction temperature
Instantaneously mix by accurate proportioning with reaction mass, greatly improve reaction efficiency and speed, obtain the high modified softening of the extent of reaction
Oil, it is to avoid in course of reaction because steric effect, material composition is complicated, react insufficient the problems such as occur, reduce reaction used time
So as to reduce production cost.
The technique that the application is proposed has following some beneficial effect：
