Oxygenation anticoagulant for diesel oil

Abstract

The invention discloses an oxygenation anticoagulant for diesel oil, which relates to the field of fuels. The oxygenation anticoagulant is prepared by mixing Fischer-Tropsch synthesis kerosene, polyoxymethylene dimethyl ether, diethoxymethane and octanol according to a specific ratio; wherein polyoxymethylene dimethyl ether and diethoxymethane are used as oxygenating agents to improve the cleanness of diesel oil combustion; and the Fischer-Tropsch synthesis kerosene can make up the problem that the dynamic property of the diesel oil is reduced due to the addition of polyoxymethylene dimethyl ether and diethoxymethane, and play a role in maintaining or reducing the condensation point of diesel oil. The preparation of the oxygenation anticoagulant is simple, the main raw materials are from coal-to-methanol and ethanol, and the cost is low. Moreover, the comprehensive performance of the diesel oil can be effectively improved, and the economic value is relatively high.

Description

technical field [0001] The invention relates to the field of fuels, in particular to an oxygen-increasing anticoagulant for diesel. Background technique [0002] Diesel is currently one of the main fuels used in motor vehicles. Compared with gasoline engines, diesel engines have the advantages of high thermal efficiency, low fuel consumption, and good durability and reliability. Therefore, they are widely used in transportation, construction machinery and other fields. However, during the use of diesel, there are the following problems: first, the particulate matter and nitrogen oxides emitted by it are relatively high, and it is increasingly difficult to meet the country's requirements for the development of clean energy; second, the indicators that reflect the low-temperature fluidity of diesel Condensation point includes pour point and cold filter point, which will change with the addition of oxygenated anticoagulant, which will affect the change of diesel grade. In the ...

However, during the use of diesel, there are the following problems: first, the particulate matter and nitrogen oxides emitted by it are relatively high, and it is increasingly difficult to meet the country's requirements for the development of clean energy; second, the indicators that reflect the low-temperature fluidity of diesel Condensation point includes pour point and cold filter point, which will change with the addition of oxygenated anticoagulant, which will affect the change of diesel grade

In the past, many small gas stations were limited by the variety of stored oil. When the temperature dropped suddenly due to sudden changes in temperature, they directly added jet fuel (No. 3 jet fuel) or light coal to reduce the freezing point of diesel to ensure that the diesel would not freeze. The result is that the cost of diesel is driven up

[0003] In the prior art, for the above-mentioned problems of diesel oil, it is usually improved by mixing additives into diesel oil, but these additives usually can only improve one of the problems, and it is difficult to achieve the desired effect on other problems, and sometimes even can lead to exacerbation of other problems
