Description
Technical field
The invention belongs to technical field of petrochemical industry, relate to a kind of environment-friendly type energy-saving diesel oil for diesel oil substitute.
Background technology
Lack of energy and environmental pollution are the serious problems that the world faces.Along with increasing rapidly of vehicle guaranteeding organic quantity, not only in world wide, the imbalance between supply and demand of petroleum fuel becomes increasingly conspicuous, and exhaust gas emission more becomes one of main source of current topsoil.China's urban air starts the feature presenting coal smoke and motor-vehicle tail-gas combined pollution, directly affects health of the masses.Motor vehicle not only directly discharges PM2.5, and oxynitride, oxysulfide, ozone, the volatile organic matter of its discharge, become the secondary pollutant of PM2.5, endanger larger through chemical transformation.From the viewpoint of resource, environment, economic dispatch, the clean alternative fuel of research and development and the feasibility problem becoming and become increasingly conspicuous of making rational use of resources.
At present about the technology of diesel oil substitute is a lot, such as waste or used plastics refining diesel oil, alcohol ether diesel, diesel oil emulsification, biofuel, utilize Some Petrochemical Byproducts combined diesel oil etc., but the ubiquitous deficiency of existing production technology comprises: the mutual solubility between each raw material is poor, easily layering; Have intense stimulus smell, discharge not environmentally; Complex manufacturing, cost is high; Multinomial physical and chemical index defective (as flash-point, condensation point, cetane value etc.); Oil consumption is high, dynamic property is poor; Processed oil poor stability, can not be mixed with GB diesel oil etc.
Summary of the invention
The object of the invention is to differ for existing market diesel quality, insufficient, the soot emissions of burning exceeds standard problems such as causing PM2.5, provides a kind of clean energy-saving diesel oil of environmental protection.
Clean energy-saving diesel oil provided by the invention is made up of the raw material mixture of following mass percent:
GB diesel oil 70-80%, polymethoxy dimethyl ether 10-20%, fatty acid methyl ester class bio oil 5-10%, isoamyl nitrate 1-2%, corrosion inhibitor 1-3%, deodovization agent 0.1-1%, pour point depressant 1-2%.
Wherein, described GB diesel oil is 0# or-10# diesel oil.
In clean energy-saving diesel oil provided by the invention, described polymethoxy dimethyl ether is the polymerization degree being Material synthesis with methyl alcohol, methylal and paraformaldehyde is the polymethoxy dimethyl ether of 3 ~ 8, and it plays a part fuel-economizing ignition dope in clean energy-saving diesel oil.
Further, described polymethoxy dimethyl ether is with methyl alcohol, methylal and paraformaldehyde for raw material, with strong acid cation resin or acidic molecular sieve for catalyzer, 110-145 DEG C, react 6-8h under 2-4Mpa condition and prepare.
The isoamyl nitrate of component described in the present invention uses as cetane number improver.
Component corrosion inhibitor in clean energy-saving diesel oil of the present invention is by cetyl trimethylammonium bromide, tricresyl phosphate (2-chloroethyl) ester dicumyl peroxide, 2,4, the mixture that 6-trichlorine phenylcarbimide, NB sodium dibutyl dithiocarbamate, two (N, N-diamyl dithiocarbamate) zinc, phthalic acid two (2-ethyl hexyl) ester are allocated with arbitrary proportion.
In clean energy-saving diesel oil of the present invention, be also added with deodovization agent, described deodovization agent can select in isobutyl acetate, dimethylbutane, ethyl butyrate, vinyl acetic monomer any one, the present invention preferably uses isobutyl acetate.
And then, also pour point depressant is added with in clean energy-saving diesel oil, described pour point depressant can select in acrylic acid alcohol ester-copolymer-maleic anhydride class, EVA, long chain alkyl naphthalene any one, preferably, the present invention uses EVA.
Clean energy-saving diesel oil of the present invention can adopt following method to prepare: under normal temperature and pressure, after being mixed by each raw material of described mass percent, leaves standstill and obtains finished product in 1-2 hour by the mode adding stirring or in-line pump circulation mediation in reactor.
Clean energy-saving diesel product outward appearance prepared by the present invention is yellow transparent liquid, and through repeatedly checking, indices reaches completely or is better than the requirement of GB diesel oil standard.
Clean energy-saving diesel oil of the present invention uses oil based on commercially available GB diesel oil, convenient buying and transport.In other the various components selected, fatty acid methyl ester as a kind of take animal-plant oil as the bio oil of waste, there is recyclability.And by the derived product polymethoxy dimethyl ether that Methanol obtains, be improve diesel combustion, raising cetane value, the oilness that improves, minimizing CO
2with NOx emission, reduce oil consumption and reduce the effective additive of one of discharging fume, compare with traditional oxygenatedchemicals methyl alcohol, methylal, dme, polymethoxy dimethyl ether can effectively reduce Flash Point of Diesel and cetane value, reduce viscosity, thus reducing vehicle to the consumption of petroleum resources, this composition effectively make use of Coal Chemical Industry product methyl alcohol simultaneously, is conducive to energy security and reduces cost, decrease soot emissions, greatly inhibit the noxious gas emission producing PM2.5.Adding of corrosion inhibitor is to suppress the swelling and metallic corrosion of General Purpose Rubber; solve the problem of oxygenatedchemicals and metallic corrosion swelling to automobile oil supply system rubber parts; the hybrid corrosion inhibitor that the present invention selects not only effectively can suppress swelling to General Purpose Rubber of clean energy-saving diesel oil itself, also has certain inhibition protection effect to engine metal part.
Due to self-contained oxygen in clean energy-saving diesel oil of the present invention, make full combustion of fuel, obviously can reduce settling and the corrosion of engine chamber, thus extend the work-ing life of engine.
Clean energy-saving diesel oil of the present invention compares with GB diesel oil, and average rate of economizing gasoline reaches 20% and powerful, diesel engine at full capacity time smoke intensity can reduce by more than 50%, belong to a kind of clean diesel, be conducive to reduce topsoil, protection of the environment.
Clean energy-saving diesel oil at low-temperature startability of the present invention is excellent, can normally use-10 DEG C to-35 DEG C time.
Clean energy-saving diesel oil of the present invention can be used in combination with the GB diesel oil of arbitrary proportion, to original result of use without any detrimentally affect.
The production technique of clean energy-saving diesel oil of the present invention is simple, and easy to operate, production process three-waste free discharge, is conducive to environmental protection.
