Description
Technical field:
The invention belongs to a kind of additive and preparation method thereof, be specifically related to a kind of alcohol ether fuel additive for automobile and preparation method thereof.
Background technology:
Alcohol-ether fuel will become following important vehicle alternative fuel with its safety, cleaning, advantage such as cheap.Alcohol-ether fuel has become the industry of national encourage growth, and alcohol ether fuel additive also will become the important auxiliary industry of new forms of energy.
At present, the preparation of alcohol ether fuel additive needs the outsourcing methylal, and methylal valency height, and, boiling point big because of its volatility is low stores, transports difficulty.Traditional methylal production process equipment investment is big, the energy consumption height, and quantity of wastewater effluent is big, pollution treatment expense height.
Summary of the invention:
The invention provides a kind of alcohol ether fuel additive for automobile and preparation method thereof, be used for solving and produce that the facility investment that the alcohol ether fuel additive for automobile process exists is big, sewage discharge is big, production cost height, the dangerous not environmental protection of production environment, the problem that yields poorly.
The present invention is by the following technical solutions:
A kind of alcohol ether fuel additive for automobile, component by following weight content is formed: light oil 30-50%, industrial methanol 35-50%, Paraformaldehyde 96 11-25%, catalyzer 1-4%, light oil adopts straight-run spirit, petroleum naphtha, stable light hydrocarbon, carbon five, coal-based liquefaction oil, the lighting end that coal tar by-product tar processing fractionation obtains, the light oil that the petroleum naphtha of coal-based synthetic oil fractionation obtains through the catalytic cracking hydrogenation, the resinous shale oil of coal-based synthetic oil fractionation any one in the light oil that the catalytic cracking hydrogenation obtains, the light oil oil product is the cut less than 200 ℃, Paraformaldehyde 96 is moisture＜and 5%, molecular weight is between 3,000 to 30,000, catalyzer prepares through following method: select for use through 900 ℃ of burnings and be crushed to fineness more than or equal to the coal-based kaolin of 1000 purposes, through the molten reaming washing of alkali and interpolation mineral acid or inorganic salt dipping, drying Calcined makes after burning again.
A kind of method for preparing alcohol ether fuel additive for automobile pumps into the mixed dissolution jar that Paraformaldehyde 96 is housed with light oil and industrial methanol mixture, treats to pump in the still kettle after Paraformaldehyde 96 dissolves fully, adds catalyzer and intensification then, stirs; When being warming up to 60 ℃, stop heating and be incubated 2 hours, continue to be warming up to most of resultant of reaction then and steam the inflow surge tank, when rising to 180 ℃, the first condenser inlet temperature stops distillation; Product in the surge tank is left standstill, pump in the dehydration still after sloughing part moisture, mix the back rerunning with dewatering agent, dewatering agent is the mixture of glycerol 40%, ethylene glycol 30% and Viscotrol C 30%, the gained cut flows into the finished product jar through second condenser condenses, can make the alcohol ether fuel additive finished product.
The present invention compared with prior art has following beneficial effect:
Alcohol ether fuel additive for automobile provided by the invention can reach the requirement of GB gasoline and methanol gasoline series standard after composite by a certain percentage with No. 90 white gasolinees of GB.Preparation method provided by the invention can reduce facility investment, increases output, reduce sewage discharge, reduces production costs, and makes safer, the environmental protection of production environment.Concerning the enterprise that uses coal-based light oil, make that the deleterious polar compound in the light oil is minimized, stability is improved greatly.Use the manufacturer of alcohol ether fuel additive to need not the outsourcing methylal, not only reduced cost, and avoided the unsafe factor of methylal on links such as storage and transportation; Mixed high boiling substance in the finished product, the security of improved storage in the finished product greatly, transporting; The quaternary material gas-liquid equilibrium and the liquid equilibrium of the methyl alcohol-methylal in the traditional technology-formaldehyde-water broken in the adding of light oil constituents, improved dewatering efficiency; The alcohol ether fuel additive that this technology makes can be directly mixes with GB gasoline and methanol gasoline and uses, and chemical fields such as coating that also can be beyond non-medicine food industry, building materials are used; Compare with traditional methylal production technique, the facility investment of this technology reduces by 2/3, whole process energy consumption drop by half, and sewage flow rate is few, and the pollution treatment expense reduces 95%.
