A kind of preparation method of ethanol petrol[technical field]
The present invention relates to gasoline processing technique field more particularly to a kind of preparation methods of ethanol petrol.
[background technique]
It is influenced as petroleum resources are more and more poorer, and often by political instability factor, also day rises gradually oil priceIt is high.In terms of ethyl alcohol is applied to vehicle fuel as a kind of reproducible biomass energy, vehicle ethanol vapour is mainly mixed into gasolineOil.Ethanol petrol relative to gasoline in emission performance advantageously.Ethyl alcohol has similar with methyl tertiary butyl ether(MTBE) (MTBE)The characteristics such as high-octane rating, octane number blending effect and rich oxygen content, opposite MTBE is then more environmentally friendly, therefore in technology and economyOn all or part of substitution MTBE.Current nearly 20 countries are promoting ethanol petrol, and China has 10 provinces and cities as E10 at presentThe pilot of vehicle-use alcohol gasoline is promoting the use of ethanol vapor.
But currently also there are many appearance of new gasoline and motor vehicle fuel, but the high expensive having, some use automobileBring counter productive, pollution emission is unfavorable etc..
[summary of the invention]
The present invention provides a kind of preparation method of ethanol petrol, can provide a kind of at low cost, simple process, wiper ringThe ethanol petrol of guarantor.
In order to solve the above technical problems, The technical solution adopted by the invention is as follows:
A kind of preparation method of ethanol petrol, the preparation method include the following steps:
Step 1: by weight percentage, providing gasoline 65-76%, industrial alcohol 12-16%, dimethyl carbonate 3-6%, isooctanol 2-5%, alkyl phenol polyoxyethylene ether 2-4%, naphtha 1.5-3%, atlapulgite 1-2% and lubricant 1-3%；
Step 2: gasoline, industrial alcohol and naphtha are added in head tank, it is naturally miscible uniform, add carbonic acidDimethyl ester, isooctanol, alkyl phenol polyoxyethylene ether, stir evenly at normal temperatures and pressures, then stir under 70-90 atmospheric pressure15-25 minutes, stand 1-2 days；
Step 3: adding atlapulgite, stirring is filtered after physical and chemical reaction 1-2 hours, obtains ethanol petrol semi-finished product；
Step 4: lubricant is added in the ethanol petrol semi-finished product, is stirred 30- in atmospheric closed space120 seconds, and be stored in closed container.
The invention has the following beneficial effects:
1, it joined industrial alcohol in the oil, reduce production cost, the smokeless odorlessness of exhaust emissions；
2, ethanol petrol explosive force prepared by the present invention is strong, the more fuel-economizing than regular gasoline, tail gas hazardous emission reduce 7 atMore than；
3, ethanol petrol clean and environmental protection prepared by the present invention reduces pollution of the vehicle exhaust to environment；
4, ethanol petrol prepared by the present invention is lost automobile engine small, improves service life of aeroengine.
[specific embodiment]
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementationExample is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is commonTechnical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protectsIt encloses.
The present invention provides a kind of preparation method of ethanol petrol, which includes the following steps:
Step 1: by weight percentage, providing gasoline 65-76%, industrial alcohol 12-16%, dimethyl carbonate 3-6%, isooctanol 2-5%, alkyl phenol polyoxyethylene ether 2-4%, naphtha 1.5-3%, atlapulgite 1-2% and lubricant 1-3%；
In step 1, due to joined industrial alcohol in the oil, thus production cost can be reduced, exhaust emissions withoutCigarette odorlessness.
Step 2: gasoline, industrial alcohol and naphtha are added in head tank, it is naturally miscible uniform, add carbonic acidDimethyl ester, isooctanol, alkyl phenol polyoxyethylene ether, stir evenly at normal temperatures and pressures, then stir under 70-90 atmospheric pressure15-25 minutes, stand 1-2 days；
Step 3: adding atlapulgite, stirring is filtered after physical and chemical reaction 1-2 hours, obtains ethanol petrol semi-finished product；
Step 4: lubricant is added in the ethanol petrol semi-finished product, is stirred 30- in atmospheric closed space120 seconds, and be stored in closed container.
Now a kind of preparation method of ethanol petrol provided by the invention is described in detail with specific embodiment.
Embodiment 1
A kind of preparation method of ethanol petrol, the preparation method include the following steps:
Step 1: by weight percentage, providing gasoline 65%, industrial alcohol 16%, dimethyl carbonate 5%, isooctanol5%, alkyl phenol polyoxyethylene ether 3%, naphtha 2%, atlapulgite 2% and lubricant 2%；
Step 2: gasoline, industrial alcohol and naphtha are added in head tank, it is naturally miscible uniform, add carbonic acidDimethyl ester, isooctanol, alkyl phenol polyoxyethylene ether, stir evenly at normal temperatures and pressures, then 15 points are stirred under 70 atmospheric pressureClock stands 1 day；
Step 3: adding atlapulgite, stirring is filtered after physical and chemical reaction 1.5 hours, obtains ethanol petrol semi-finished product；
Step 4: being added lubricant in the ethanol petrol semi-finished product, is stirred in atmospheric closed space 60 seconds,And it is stored in closed container.
Embodiment 2
A kind of preparation method of ethanol petrol, the preparation method include the following steps:
Step 1: by weight percentage, providing gasoline 75%, industrial alcohol 12%, dimethyl carbonate 3%, isooctanol3%, alkyl phenol polyoxyethylene ether 2%, naphtha 1.5%, atlapulgite 1.5% and lubricant 2%；
Step 2: gasoline, industrial alcohol and naphtha are added in head tank, it is naturally miscible uniform, add carbonic acidDimethyl ester, isooctanol, alkyl phenol polyoxyethylene ether, stir evenly at normal temperatures and pressures, then 20 points are stirred under 90 atmospheric pressureClock stands 1.5 days；
Step 3: adding atlapulgite, stirring is filtered after physical and chemical reaction 2 hours, obtains ethanol petrol semi-finished product；
Step 4: being added lubricant in the ethanol petrol semi-finished product, is stirred in atmospheric closed space 90 seconds,And it is stored in closed container.
It is detected by experiment, finds ethanol petrol burning prepared by the present invention sufficiently, the shake of generation is quick-fried few, damages to engineConsume small, and the pernicious gas that generates is considerably less after burning, and smokeless odorlessness can meet the requirement of national standard 6 completely.
The invention has the following beneficial effects:
1, it joined industrial alcohol in the oil, reduce production cost, the smokeless odorlessness of exhaust emissions；
2, ethanol petrol explosive force prepared by the present invention is strong, the more fuel-economizing than regular gasoline, tail gas hazardous emission reduce 7 atMore than；
3, ethanol petrol clean and environmental protection prepared by the present invention reduces pollution of the vehicle exhaust to environment；
