Technical field

The present invention relates to technical field of methanol fuel, in particular to a kind of M100 methanol fuel for vehicles performance improver and system Preparation Method.

Background technique

China is a populous nation, and industry and domestic energy demand are huge, meanwhile, China is a coal resource again Abundant and poor petroleum resources country, fundamental realities of the country factor decide China's rapid economic development, are necessarily faced with economic increasing Long and environmental protection dual-pressure.Problem is the energy and resource consumption big country, and Chinese resource environment contradiction becomes increasingly conspicuous.Change Become production of energy and consumption pattern, the renewable and clean energy resources resource such as development and utilization renewable energy fuel is sustainable to establishing Energy resource system promotes national economic development and is of great significance with environmental protection.In recent years, as country is to energy security and ring The continuous attention of border protection, a series of policies and regulations are put into effect in succession.

In December, 2009 national standard " Vehicular methanol petrol (M85) " is formally implemented, and mentions for high proportion Vehicular methanol petrol Standard foundation is supplied.

Methanol can make the liquid fuel of raw material large-scale production, mature production technology with coal and natural gas etc., and storage makes With safe and reliable.Vehicular methanol petrol is to add methanol in gasoline in a manner of blending, and is prepared into methanol gasoline and is mixed It burns, is methanol fuel application method the simplest, generally according to methanol content, methanol gasoline is divided into M3~M85, wherein M Indicate methanol, the volume fraction of digital representation methanol.

In recent years, the research application of (M3~M85) methanol gasoline has been achieved for certain effect, but the reason based on methanol Change property, gasoline of high proportion methanol directly uses within the engine, still will appear and is cold-started under difficult, power under low temperature environment A series of problems, such as drop, corrosivity.

Summary of the invention

The present invention for the above technical issues, provides a kind of M100 methanol fuel for vehicles performance improver and preparation side Methanol is generated M100 methanol fuel for vehicles finished product by mixing, stirring, stand with performance improver by method.M100 Vehicular methanol Fuel uses under conditions of not changing existing engine structure, solves methanol fuel for vehicles and directly uses appearance in engine The problems such as oil product meets water stratification, emulsification, cold-starting difficulty, high temperature vapour lock, and corrosion is swollen, and power dropping, oil consumption are increased.

To achieve the above object, specific technical solution of the present invention is as follows:

A kind of M100 methanol fuel for vehicles performance improver comprising the following components of mass percent is material allocation system At:

Preferably, the volume ratio of the modifying agent and methanol are as follows: 1: (40~60).

Further, the volume ratio of the modifying agent and methanol are as follows: 1: 49.

The above-mentioned M100 methanol fuel for vehicles performance improver of the present invention, is a kind of compound additive, using following methods It is prepared:

Isopropanol, methyl tertiary butyl ether(MTBE), ethanol amine mixing temperature rising reflux are reacted into 180~240min, obtain component A；

By cyclohexanol, Tween 80, oleic acid 90~120min of hybrid reaction, component B is obtained；

Methyl tertiary butyl ether(MTBE), isopentane, petroleum ether are uniformly mixed to obtain improved properties with obtained component A, component B Agent.

Wherein, when methyl tertiary butyl ether(MTBE), isopentane, petroleum ether, component A, component B being mixed, mixing temperature is controlled It is 10~20 DEG C.

Will performance improver prepared by the present invention be added methanol in, under room temperature and condition of normal pressure carry out physical modulated and, i.e., It is adjustable to obtain M100 methanol fuel for vehicles, and the M100 methanol fuel for vehicles prepared meets the automobile-used first of GB/T 23799-2009 Technical requirements as defined in alcohol gasoline (M85).

The prior art is compared, M100 methanol fuel for vehicles performance improver of the present invention has the advantage that

(1) effect of dissolving each other with methanol is good, product transparent clear, free from admixture, not stratified under the conditions of -35 DEG C；

(2) water-resistance is good, and for water resistant ratio up to 1%, stability is good, and storage life was up to 1 year or more；

(3) bench test shows that its cold start-up, dynamic property, fuel economy, the feature of environmental protection and 95# gasoline are substantially suitable；

(4) copper strip test shows that the corrosivity of M100 methanol fuel for vehicles performance improver of the present invention is smaller.

Specific embodiment

The following example is only used for that the present invention is described in detail, it will be appreciated that the scope of the present invention is not limited to These embodiments.
