Abstract
The invention relates to a methanol-gasoline blend fuel and a preparation method thereof, belonging to the technical field for preparing fuel gasoline. The methanol-gasoline blend fuel is made of the components with the weight percentage: 55-98% of gasoline, 1-44% of methanol and 1-10% of miscible solvent; wherein, the miscible solvent is more than one in dimethoxymethane, diethoxymethane and methoxyl ethoxy methane. The materials are put into a container to be evenly mixed together according to the mixture ratio, so that the product of the invention can be prepared. The invention has the advantages that as the miscible solvent with certain proportion is added into the methanol-gasoline, the problems of poor stability, bad intermiscibility and easy delamination can be effectively solved; the selected miscible solvent has the boiling range of 42-78 DEG C which is within the boiling range of main components of gasoline, thus not only effectively avoiding the Reid vapour pressure of the methanol-gasoline blend fuel rising and the risks such as remnant and the like, but also being safe and reliable in use.
Description
Technical field
The present invention relates to a kind of methanol gasoline mixed fuel and preparation method thereof, belong to the preparing technical field of fuel gasoline.
Background technology
Along with socioeconomic fast development, global energy shortage and environmental pollution problems become increasingly conspicuous, and therefore the substitute that methyl alcohol and ethanol act as a fuel is subjected to increasing attention.But there is shortage of resources in ethanol, and expensive problem is unfavorable for that it applies further.And methyl alcohol can be made by Sweet natural gas, gasification, timber, stalk, rubbish even carbonic acid gas, so wide material sources, and is cheap, thereby have the better development prospect.But because methyl alcohol is different with the gasoline physico-chemical property, demixing phenomenon all very easily appears in methanol gasoline under extreme low temperature and high temperature, have influence on its storage and safe handling; In addition, because methyl alcohol polarity is very strong, can infinitely dissolve each other with water, the existence of moisture can make the critical temperature of dissolving each other of methanol gasoline improve, even the moisture that from air, absorbs in some cases, also can destroy the intermiscibility of methyl alcohol and gasoline, the stability problem that therefore solves methanol gasoline is its key of applying.
Solution to this problem mainly is to use additive in methanol gasoline at present, for example Soxylat A 25-7, Polyglycerine esters surface active agent etc.But this type of tensio-active agent boiling point is higher, easily causes potential risks such as residual.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the invention provides a kind of good stability, be difficult for stratified methanol gasoline mixed fuel.
The present invention also provides the preparation method of described methanol gasoline mixed fuel.
The present invention is achieved by the following technical solutions:
Described methanol gasoline mixed fuel, make by the raw material of following weight per-cent meter:
Gasoline 55-98%, methyl alcohol 1-44%, miscible agent 1-10%; Described miscible agent is more than one in Methylal(dimethoxymethane), methylene diethyl ether and the methoxy ethoxy methane.
Described various raw material is the commercially available prod.
For making product have preferable performance, described miscible agent is preferably Methylal(dimethoxymethane), methylene diethyl ether and methoxy ethoxy methane three's mixture; More preferably, to be Methylal(dimethoxymethane), methylene diethyl ether and methoxy ethoxy methane mix by the weight ratio of 3:4～6:1.5～2.5 miscible agent.
For making product have better stability, described methanol gasoline mixed fuel is made by the raw material of following weight per-cent meter: gasoline 83%, methyl alcohol 15%, miscible agent 2%; Described miscible agent is mixed by the weight ratio of 3:5:2 by Methylal(dimethoxymethane), methylene diethyl ether, methoxy ethoxy methane.
Product of the present invention adopts following method preparation: gasoline, methyl alcohol and miscible agent are put into the container mixing by proportioning get final product.
Methylal(dimethoxymethane) is good because of its solvability, and physicochemical property is good, can be used as solubility promoter, be added in the methanol gasoline, but effect is limited; If need to improve the performance of methanol gasoline, generally also need add the additive of other types.The inventor is after the experiment and comparison multiple additives and performance thereof carried out repeatedly, find the action effect that methylene diethyl ether, methoxy ethoxy methane can play equally increases methyl alcohol and gasoline intermiscibility, if the mixture that adds above-mentioned three kinds of compounds in methanol gasoline can effectively increase the stability of methanol gasoline as solubility promoter.
The wood beneficial effect of the invention is:
(1) by adding a certain proportion of miscible agent, it is bad to have solved methanol gasoline stability effectively, and intermiscibility is poor, easy stratified problem, but standing storage;
(2) selected its boiling range of miscible agent is 42-78 ℃, is within the gasoline master composition boiling range, both can effectively avoid the Reid Vapour Pressure of methanol gasoline mixed fuel to raise, and also can avoid residual equivalent risk, and is safe and reliable;
(3) preparation technology is simple, need not specific installation, has reduced production cost, is easy to promote.
