Description

Formulation, preparation method and product of gasoline miscible compound emulsifier and utilization of the product

Method and production of producing miserable emulsified gasoline

Technical field

The invention relates to an emulsifier, in particular to a formula of a gasoline water-incorporated compound emulsifier; the invention also relates to a method and a product thereof for preparing a gasoline hydrating compound emulsifier by using the formula, and a compound emulsifier using a gasoline water-mixing agent A method of producing emulsified gasoline and a product thereof.

Background technique

The biggest disadvantage of using ordinary gasoline is that the combustion is insufficient and incomplete, so the industrial exhaust gas emitted is too high, which not only causes serious pollution to the environment, but also is a waste of energy in today's increasingly scarce oil. A good way to solve this problem without meeting the market price with the best economic efficiency is to formulate ordinary gasoline into water-containing emulsified gasoline. Water and oil are two different substances that are incompatible with each other. In order to minimize the contact area between the two and reduce the energy of the system, the oil and water meet to form two layers of bifurcation. In order to mix oil and water into an emulsified form and to achieve an optimum emulsification effect of the emulsified gasoline, a suitable emulsifier is required. In addition, there is a need to solve the problems of the ratio of ordinary gasoline, water and emulsifier, and the method of formulating emulsified gasoline, which are major problems that plague the research and application of emulsified gasoline. It is also these difficulties that make it difficult to make substantial progress in emulsified gasoline.

4, good dynamic performance, with a second fuel-saving effect, the average fuel economy is 15% ~ 20% or more, the economic benefits are particularly excellent.

Embodiments of the invention

Hereinafter, the gasoline-water-incorporated compound emulsifier of the present invention and the emulsified gasoline produced using the emulsifier will be further described in detail in conjunction with specific examples.

Examples 1 to 2: The components of the formulation shown in Table 1 were placed in a beaker or other similarly functional container by weight ratio, and then placed in a 60-80 ° C water-soluble tank for heating, 5 to 10 minutes, and slightly After stirring, the gasoline-injected compound emulsifier of the present invention is obtained, and the emulsifier is a brown paste-like viscous body. Table 1

2 %〜1· 5 %和。 By weight, the gasoline-water compound emulsifier obtained in the above-mentioned Examples 1 to 2 was added to the conventional gasoline (base oil, the base oil of the present embodiment was 90 ^# unleaded gasoline). The water is 13.5% to 15%, and then the water-in-oil type emulsified gasoline for transportation or industrial use can be obtained by stirring for 5 to 10 minutes using a general mechanical stirring device. The obtained emulsified gasoline is tested according to the test method stipulated by the Chinese GB mandatory national standard, and the comparison results of various technical indexes and base oil are shown in Table 2.

It can be seen from Table 2 that the technical indexes of the emulsified gasoline of the present invention are consistent with the base oil in the embodiment, that is, comply with the GB mandatory national standard, that is, the emulsified gasoline of the present invention has the same as ordinary gasoline (base oil). Use value. The emulsified gasolines obtained in Examples 1 to 2 and the above-described production method were subjected to an engine bench test, a vehicle road test, and a practical vehicle application test. The test results show that the combustion efficiency, antiknock performance and dynamic performance of the emulsified gasoline of the present invention are significantly superior to those of the base oil.

The above test proves that the emulsified oil of the present invention has higher combustion efficiency than the base gasoline and is therefore more complete and more complete than the base gasoline combustion. Its emission concentration is lower than that of EU 4 (EU 0BD standard, NO. 4), which means that the environmental performance is very good. At the same time, since the combustion efficiency is higher than that of the base gasoline, the emulsified gasoline of the present invention has two fuel-saving effects, and the average fuel economy is 15 to 20% or more.
