Abstract
The invention belongs to the field of fuels and relates to a vehicle high-proportion methanol gasoline and a preparation method thereof. The vehicle high-proportion methanol gasoline comprises the following components in percentage by weight: 85 to 90 percent of methanol, 3 to 4 percent of solvent oil, 5 to 10 percent of No. 90 national standard gasoline and 1 to 2 percent of additive, wherein the additive is prepared by blending sodium hexadecyl sulfonate, calcium hexadecyl sulfonate, liquid naphthenic acid, methylal, nitromethane and C3-C8 monohydric alcohol. The high-proportion methanol gasoline of the invention overcomes the disadvantages of the traditional high-proportion methanol gasoline under the condition of no change of the vehicles; each index completely meets the standard of vehicle methanol gasoline M85 of 'GB/T23799-2009'; and the vehicle high-proportion methanol gasoline can be well applied to vehicles.
Description
Technical field
The invention belongs to the fuel field, be specifically related to a kind of high-proportion methanol gasoline for vehicle, also relate to its preparation method simultaneously.
Background technology
Energy dilemma and environmental pollution are the two large problems that the world today faces, and therefore, actively seek and develop the cardinal task that clean energy and substitute energy have become countries in the world.Methyl alcohol has the oxygen level height, the octane value height, and characteristic such as environmental pollution is little, and wide material sources are ideal vehicle alternative fuels.The present methanol gasoline of using mainly is a methanol content low 30% below than the methanol gasoline that is listed as and methanol content at the gasoline of high proportion methanol more than 85%.Low ratio methanol gasoline, not only energy substitution rate is not high, and in use also has high temperature vapour lock, low-temperature stratification, and life-time service can produce corrosion to fuel transfer system and automobile component.Though gasoline of high proportion methanol has improved the substitution rate of the energy greatly, need to change the electrical control system of engine in use and when low temperature the cold start-up difficulty, so make gasoline of high proportion methanol can not obtain excellent popularization and use.
Summary of the invention
The purpose of this invention is to provide methanol gasoline of a kind of vehicle high-ratio and preparation method thereof, overcome the defective that existing high-proportion methanol gasoline for vehicle exists under the situation of vehicle need not to reequip, it is more convenient to make that gasoline of high proportion methanol uses on vehicle.
The present invention is achieved in that described high-proportion methanol gasoline for vehicle is formulated by following weight percentages:
85～90 parts of methyl alcohol
3～4 parts of solvent oils
5～10 parts in 90# GB gasoline
1～2 part of additive
Additive is by weight percentage by 5%～15% sodium cetanesulfonate, 5%～15% hexadecyl calcium sulphonate, and 5%～10% liquid ring alkanoic acid, 15%～25% methylal, the monohydroxy-alcohol of 5%～10% Nitromethane 99Min. and 40%～60%C3～C8 mixes.
Described additive has the corrosion of inhibition, improves the calorific value of methanol fuel, increases power, the effect of stabilising system.
Described solvent oil is that 120# solvent oil and 200# solvent oil mix by arbitrary proportion.
The monohydroxy-alcohol of described C3～C8 is one or more the arbitrary proportion mixture in Pentyl alcohol, the trimethyl carbinol, propyl carbinol, n-hexyl alcohol, Virahol, the primary isoamyl alcohol.
Preparation method of the present invention:
Methyl alcohol, solvent oil, 90# GB gasoline, additive are placed container in proportion, stir, leave standstill tinning after 3 minutes.
Use the M85 methanol gasoline of the present invention's preparation to compare with 93# GB gasoline, the octane value height, anti-knocking property are good, improved the utilising efficiency of the compression ratio and the fuel of engine.By the experimental data of car load platform experiment as can be known: the M85 methanol gasoline with the present invention's preparation is compared with 93# GB gasoline, and power does not descend, and 0～80 km/hour pick-up period is suitable with 93# GB gasoline.Aspect exhaust emissions, engine is when low idling and high idle speed, and discharge amount of exhaust gas obviously descends.CO descends 50%, and HC descends 8.3% and 9.1%.
High-proportion methanol gasoline for vehicle of the present invention can directly use on the vehicle of EFI formula engine, need not to reequip vehicle; Cold starting performance is good, and in subzero 40 ℃, vehicle can normally start; Life-time service can not produce corrosion to fuel transfer system and automobile component; Can mix by arbitrary proportion with 90#, 93#, 97# GB gasoline, can not influence result of use.
