Abstract

The invention discloses a preparation method of environment-friendly dimethyl carbonate diesel for an automobile. The environment-friendly dimethyl carbonate diesel comprises the following components by weight percent: 50-300ppm of 2,6-tertiary butyl p-cresol, 10-200ppm of tris(2,4-ditert-butyl phenyl) phosphite, 10-200ppm of thiadiazole or benzotriazole, 10-500ppm of isooctyl nitrate or ethyl nitrate, 100-500ppm of lubricity improver, 9.982-29.83% of dimethyl carbonate and 70-90% of diesel. The preparation method comprises the following steps of: adding various additives into dimethyl carbonate and then mixing to obtain a dimethyl carbonate solution I; and then mixing the dimethyl carbonate solution I and dimethyl carbonate with the diesel to obtain the dimethyl carbonate diesel. The dimethyl carbonate diesel disclosed by the invention has the advantages of good stability, corrosion resistance and environmental protection performance, can be intersoluble with the diesel in any proportion, and is simple to prepare, low in cost and strong in competitive power.

Description

technical field [0001] The invention relates to the technical field of substitute fuel for diesel engines, in particular to a clean and environment-friendly dimethyl carbonate diesel and a preparation method thereof. Background technique [0002] In recent years, the continuous rise of international oil prices has brought a huge impact on our country's economy. The so-called "safety warning line" whose dependence on foreign oil exceeds 50% has now reached more than 55%, becoming the most important in the world. energy consumption importing country. Due to the rapid growth of my country's demand for oil and the unstable factors in the world's hot spots, the country's energy security is facing serious challenges. Therefore, the development of new clean alternative fuels is of great significance for improving the performance of diesel engines, reducing dependence on oil resources, and ensuring energy security. . [0003] Diesel engines have the advantages of high power, low fu...
