Abstract
The invention discloses component oil capable of reducing saturated vapor pressure of methanol gasoline, which is prepared from 20 to 25 percent of No.120 solvent oil, 20 to 25 percent of No.200 solvent oil, 5 to 10 percent of methylbenzene, 3 to 5 percent of dimethylbenzene, 20 to 30 percent of heavy naphtha and 20 to 25 percent of catalytic reformed gasoline. The component oil is mainly used for blending with traditional national standard No.90 and No.93 gasoline to prepare low proportional methanol gasoline with the methanol content of 10 to 30 percent, so that the positive deviation of the saturated vapor pressure of the low proportional methanol gasoline is rectified, the saturated vapor pressure of the low proportional methanol gasoline is effectively reduced, the vapor pressure is ensured to be not high when the national standard No.90 and No.93 gasoline are doped with the low proportional methanol, a 'vapor lock' phenomenon cannot happen in high temperature weather, and an engine can normally work.
Description
Technical field
The invention belongs to the methanol fuel for vehicles technical field, relate to a kind of methanol gasoline component oil, particularly relate to a kind of low ratio Vehicular methanol petrol component oil.Component oil of the present invention can effectively reduce the saturated vapor pressure of low ratio methanol gasoline.
Background technology
The world energy sources reserves are shortage day by day, and environmental problem is serious day by day, and energy problem and environmental problem have caused the great attention of countries in the world, and therefore, seeking new cleaning substitute energy has become global problem.The positive high speed development of China's economy, surplus the automobile pollution 7,000 ten thousand at present, the annual oil major part that consumes needs import.The energy and environmental problem are restricting China's rapid economy development.
China belongs to oil-poor weak breath but the country of relative rich coal, and it is fully feasible producing the alternative part oil of methyl alcohol with coal.Methyl alcohol has following characteristics as good alternative fuel: 1. aboundresources, and price is suitable, satisfies the large-scale promotion needs; 2. fuel value, especially heat vale of mixture can satisfy combustion engine powered performance requriements; 3. help reducing discharge of poisonous waste; 4. can satisfy the requirement of aspects such as vehicle launch performance, rideability and acceleration characteristics; 5, energy density is higher, the storage convenient transportation; 6. do not need to change engine, technical feasible; 7. on the existing fuel handling distribution system energy usefulness.
Methanol content is mixed the burning methanol gasoline in 10～30% low ratio and is passed through pilot conversion, proof can adapt to the service requirements of vehicle fully, be ideal motor spirit substitute, and discharge of poisonous waste is lower by 35% than pure gasoline, is a kind of vehicle fuel of abrasive.
But low ratio methanol gasoline is compared with GB gasoline, has a serious problem---saturated vapor pressure height in the popularization process.Low ratio methanol gasoline occurs oiling machine easily at hot weather and adds problem not fuel-displaced and automobile " breathing heavily ", and this problem is seriously restricting low ratio methanol gasoline particularly popularization of southern area in the whole nation.
Summary of the invention
The purpose of this invention is to provide a kind of low ratio methanol gasoline component oil, this component oil can reduce the saturated vapor pressure of methanol gasoline, solves the problem of low ratio methanol gasoline high temperature vapour lock.
Low ratio methanol gasoline of the present invention is meant methanol content at 10～30% methanol gasoline, and the component oil that is used for this methanol gasoline is formulated by following components in weight percentage:
120# solvent oil 20～25% 200# solvent oils 20～25%
Toluene 5～10% dimethylbenzene 3～5%
Heavy naphtha 20～30% catalytic reforming gasoline 20～25%.
In the various components that component oil of the present invention uses, 120# solvent oil, 200# solvent oil, toluene, dimethylbenzene are Chemicals; Heavy naphtha is the product of 40～205 ℃ of boiling ranges, saturated alkane about 70%; Catalytic reforming gasoline is the heavy gasoline of aromaticity content more than 40%.Above product all has sale on various places refinery or market, raw materials quality is stablized, easily purchased.
The component oil saturated vapor pressure that the present invention is mixed with is lower, it is mixed according to certain ratio behind base oil, prepare low ratio methanol gasoline, can correct the plus deviation of low ratio methanol gasoline saturated vapor pressure, effectively reduce the saturated vapor pressure of low ratio methanol gasoline, guarantee that GB 90# or 93# gasoline vapour pressure when mixing the burning low-proportion methanol does not raise, " vapour lock " phenomenon can not take place when hot weather, and engine can works better.
Component oil of the present invention and traditional GB 90#, 93# methanol gasoline base oil are mixed, can reduce the saturated vapor pressure 10～17kPa of low ratio methanol gasoline, make the saturated vapor pressure basically identical of itself and GB 90# or 93# gasoline, guarantee its normal use at hot weather.
Simultaneously, component oil of the present invention also has effects such as stabilising system, enhancing power, and life-time service does not corrode engine and fuel transfer system, can guarantee that oiling machine is normally fuel-displaced.
Component oil of the present invention can mix use with arbitrary proportion with GB 90#, 93# gasoline, does not influence result of use.Component oil products production cost of the present invention is low, and effect is obvious, is easy to promote.
