Description
Technical field
The present invention relates to a kind of emulsifying agent, particularly a kind of environmental protection type diesel fuel emulsifier.
Background technology
Energy and environment are two large problems that human society faces, and existence has great importance to human society for energy shortage, environmental pollution, and the obnoxious flavour that discharges after oil inflame is an important factor of environmental pollution.Therefore, how to solve energy shortage, problem of environmental pollution with regard to the problem that become society scientific circles and pay close attention to most, save energy, environmental contamination reduction have caused the mankind's great attention.
As far back as just just existing people's proposition of eighties of last century, water is mixed in oil fuel and improved this imagination of burning, the U.S., USSR (Union of Soviet Socialist Republics) and some industrial countries of Europe, start the applied research of emulsification water blending fuel oil, due under condition at that time, the emulsified fuel state of the art is lower, energy problem is not outstanding, and the Emulsified Fuel Technology at Power development is in low state more slowly.
Later stage nineteen fifties; environment and development contradiction is day by day obvious; oil crisis starts to occur; the oil fuel technology for mixing water that possesses the dual function of energy-saving and pollution-reducing obtains to pay attention to; the U.S., USSR (Union of Soviet Socialist Republics), Japan etc. all classify this technology as national main project and develop research; and obtaining positive application achievements, in first annual meeting of the world of holding in July, 1981 burning association, the Emulsification of Fuel Oil emulsifying combustion is listed in one of three large conservation measuress.China from the fifties end, also carries out active research in this field, and obtains certain achievement.Early eighties, in view of China's energy shortage, State Planning Commission, State Scientific and Technological Commission, the Chinese Academy of Sciences dispatch a joint document, fabric study's Emulsified Fuel Technology at Power, the numerous and confused input research of national correlative study mechanism and individual, obtained certain practical achievement.
Water is polar compound as everybody knows, petroleum products is by the non-polar compound hydrocarbon composition, water and oil are immiscible, make and both become the mixed solution that dissolves each other, need by external force or add tensio-active agent, wherein a kind of uniform liquid is dispersed in another kind of liquid, become metastable mixed solution, in fine chemistry, this mixed solution is referred to as emulsion, and the emulsion that is comprised of oil fuel (kerosene, gasoline, diesel oil, heavy oil, residual oil) and water just is called as emulsion fuel.The diesel oil emulsification technology is by certain processing compound with diesel oil, water and emulsifying agent, in mechanical means by certain technological process of production, form a kind of " water-in-oil " type diesel oil emulsification through Over emulsfication, comprising the development of emulsification mechanical means and the synthetic and screening of emulsifying additive.
Emulsified fuel oil is the same with common emulsion, also be divided into water-in-oil-type (W/O) and oil-in-water-type (O/W), in water-in-oil type emulsion fuel oil, water is to be suspended in equably in oil with disperse phase, be called as disperse phase or interior phase, oil fuel wraps in the skin of the globule, becomes external phase or foreign minister.Our present being seen most of emulsified fuel oils are all water-in-oil type emulsified fuels.Oil-in-water type emulsion oil fuel is just in time opposite with water-in-oil-type.
Emulsified fuel oil belongs to thermodynamic unstable system, under the effect of external force field (gravity etc.), emulsified fuel oil is layering gradually, its minute, interval velocity became quadratic relationship with the radius of drop, not only do not play the energy-saving and pollution-reducing effect after emulsified fuel oil generation layering, serious meeting causes burning to interrupt, and this must select suitable emulsifying device, suitable particle diameter will be distributed to mutually, so that emulsified fuel oil reaches the relatively stable period of service requirements in emulsified fuel oil.
The unsettled major cause of emulsion fuel oil systems is that water oil is immiscible, and their surface tension separately form the interfacial tension of intersection, and interfacial tension is shunk the water-oil interface liquid phase gradually, causes finally agglomeration separation separately.Emulsifying agent is tensio-active agent, and its Main Function is to reduce interfacial tension.
Tensio-active agent; generally all polar group and nonpolar group two portions, consist of on chemical structure, polar group is soluble in water has hydrophilic nmature, therefore be called hydrophilic group; nonpolar group is soluble in oil; therefore be called oleophilic group, add emulsifying agent in oil-water system after, hydrophilic group is soluble in water; oleophilic group is dissolved in oil; so just form the interfacial film of one deck densification between oil-water two-phase, reduced interfacial tension, simultaneously drop is shielded.On the other hand, because absorption and the effect such as friction make liquid droplet charged, charged drop forms double electrical layers in the both sides at interface, because the repulsive interaction of electrostatic double layer makes drop be difficult to gathering, thereby has improved the stability of emulsified fuel oil.
Kinds of surfactants is very many, but generally by following formal classification:
(1) divide by solvability: water-soluble and oil soluble.
(2) divide by the decomposable ions in water: ionic and non-ionic type.
(3) divide by the ionic in water: anionic, cationic and amphoteric ion type.
At present more in emulsifier for fuel oil is to adopt the tensio-active agent of several different activities such as anionic, cationic, nonionic surface active agent to carry out composite use, to reach comparatively ideal stabilising effect.
During different oil product preparation oil in water emulsion, their emulsifying agent hydrophile-lipophile balance values used (HLB value) are not identical, and this all must be by series of experiments and goes in actual use concrete allotment.Present diesel oil emulsifier on the market is large in the variety, but great majority are in order to consider cost and emulsifying effectiveness, sodium alkyl benzene sulfonate (ABS) and alkylphenol polyoxyethylene (APEO) have been adopted in a large number in formula, although the emulsifying agent emulsifying effectiveness of these structures is good, but biological degradation is bad or harmful to water body, belongs to environment harmful.
