Abstract

The additive for synthetic water-diesel oil fuel consists of fatty alcohol polyoxyethyleneether 6.8 wt%, alkylene phenol polyvinyl ether 5.2 wt%, amyl nitrate 7.4 wt%, high-alkali barium sulfonate 5.6 wt%, ethylene-acrylate copolymer 5.5 wt%, sorbitan monostearate polyoxyethyleneether 40 wt%, Span-60 10 wt%, sorbitan trioleate polyoxyethyleneether 10.3 wt% and ferrocene 9.2 wt%. It is produced through mixing while stirring at high speed to react and letting stand to eliminate bubble and become emulsion. The additive is used in producing mixed water-diesel oil fuel, which has the same performance as diesel oil and can save oil by 20-30 %.

Description

Water and diesel oil synthetic fuel additive and manufacture method and application

Technical field

The present invention relates to the employed additive of a kind of synthol and manufacture method and application.

Background technology

World wide meat petroleum resources shortage at present, and the appearance of synthol has solved the problem of energy deficiency greatly, wherein with water and the mixed mutually emulsion gasoline of gasoline, production with the alcohol gasoline replacing, experiment is a lot, the regeneration of how to save diesel oil and strengthening it, make its more compliance with environmental protection requirements, prefered method remains with the synthetic diesel oil emulsification, this wherein the employed additive of synthol play crucial effect, there are some shortcomings in existing synthetic fuel additive, for example: body is had corresponding corrosion, temperature range requires high during use, effect is obvious when only being confined to 0 ℃-30 ℃, shelf lives has only 10 days in addition, is unfavorable for suitability for industrialized production, and is energy-conservation not obvious etc. when high-speed diesel engine is used.

Summary of the invention

The purpose of this invention is to provide a kind of additive and manufacture method and application that makes water and two kinds of inconsistent liquid of diesel oil that chemistry, physical change generation New-type fuel (diesel oil emulsification) take place rapidly.

Additive of the present invention is a kind of nonionic surface active agent, is made up of by a certain percentage clean-out system, defoamer, cetane number improver, smoke suppressor, pour point depressant, lipophilic emulsifier, hydrophilic emulsifier, linking agent, ignition dope etc.

The composition of water and diesel oil synthetic fuel additive, be by weight percentage: fatty alcohol-polyoxyethylene ether 6%-7.5%, alkylene phenol polyvinyl ether 4.5%-5.5%, nitric acid is defended ester 6.8%-7.8%, high alkalinity barium sulfonate 5%-6.5%, ethylene acrylate copolymer 5%-6%, the stearic Soxylat A 25-7 35%-45% of sorbitan list, sorbitol anhydride monostearate 8%-15%, polyoxyethylene sorbitol acid anhydride trioleate 9%-11%, ferrocene 8.5%-9.6%.

The manufacture method of water and diesel oil synthetic fuel additive is with fatty alcohol-polyoxyethylene ether, alkylene phenol polyvinyl ether, nitric acid is defended ester, the high alkalinity barium sulfonate, ethylene acrylate copolymer, the stearic Soxylat A 25-7 of sorbitan list, sorbitol anhydride monostearate, polyoxyethylene sorbitol acid anhydride trioleate, ferrocene is mixed in proportion, high-speed stirring, reaction, peaceful froth breaking becomes the emulsion liquid additive.

With above-mentioned additive by weight percentage: water 20%-30%, diesel oil 70%-80%, per 1000 kilograms add 1 kilogram of fluid additive, and it is diesel oil emulsification that mixing back high-speed stirring becomes uniform liquid.

Advantage of the present invention is: 1, add anti-rust cleaning agent, the formation of adjusting prescription simultaneously makes the pH value of additive be neutral, and then can not corrode body.2, add ignition dope, it can fully be burnt under the situation of running up, reach energy-saving effect.3, add and stationary phase that stablizer is harmonious profit to be higher than 10 days and to reach 30 days, satisfy the purpose of suitability for industrialized production and commercial distribution.4, the oil in water emulsion of allotting all can use, and effect is identical at-15 ℃-40 ℃.

Embodiment

Manufacture method of the present invention is with following raw material: fatty alcohol-polyoxyethylene ether 6.8%, alkylene phenol polyvinyl ether 5.2%, nitric acid is defended ester 7.4%, high alkalinity barium sulfonate 5.6%, ethylene acrylate copolymer 5.5%, the stearic Soxylat A 25-7 40% of sorbitan list, sorbitol anhydride monostearate 10%, polyoxyethylene sorbitol acid anhydride trioleate 10.3%, ferrocene 9.2% weighing by weight percentage respectively mixes; Put into 600 rev/mins high-speed stirring jar, normal temperature stirred 20 minutes; Enter reactor then and stir 300 rev/mins of stirring velocitys, 25 ℃-40 ℃ of temperature, 1 kilogram of pressure, 30 minutes time; Peaceful jar, normal temperature, normal pressure, froth breaking 2 hours; Get final product by the various dose splendid attire.When water and diesel oil synthetic fuel additive are used, precentagewise: water 20%-30%, diesel oil 70%-80%, per 1000 kilograms add 1 kilogram of fluid additive, and it is diesel oil emulsification that mixing back high-speed stirring becomes uniform liquid.

Similar to natural diesel oil with the various physical indexs of diesel oil emulsification that this additive is made with chemical index, it is widely used in engineering machinery, generating set, vehicle and boats and ships, the oil-firing boiler etc. that all are fuel with diesel oil, use its engine power performance of machinery of diesel oil emulsification constant substantially, engine is had no side effect, rate of economizing gasoline reaches 20%-30%, smoke intensity reduces 40%, the exhaust emissions obnoxious flavour reduces 80%, be more than 30 days oily stationary phase, and can dissolve each other generally with natural diesel oil, as taking place, precipitation can pass through the mechanical means regeneration.The color and luster of emulsifying agent is isabelline, and viscosity is 300-120 pascal when 0 ℃-40 ℃ of temperature, and produced diesel oil emulsification is an oyster white, and kinematic viscosity is similar to diesel oil.
