Method for producing synthetic diesel oil

Abstract

The invention provides a method for producing synthetic diesel oil. The diesel oil comprises the following components in percentage by weight: 80 to 84 percent of methanol, 15 to 18 percent of purified petroleum benzin, 2.5 to 3 percent of isooctyl nitrate, 0.2 to 0.5 percent of methyl propionate and 0.01 to 0.05 percent of naphthenic acid. The preparation method comprises the following steps: mixing and stirring the components in a vessel after adding the components in the vessel in sequence; standing the mixture for 30 minutes; and filtering the mixture. The method has the advantages of reasonable components, simple process, high heat value and no pollution, and can be widely applied to various diesel machines to replace fuel for use.

Description

technical field [0001] The invention relates to a synthetic diesel which can be used as fuel for various diesel machines, in particular to a production method of the synthetic diesel and a preparation method thereof. Background technique [0002] Due to the continuous reduction of petroleum and mineral resources, the development and utilization of new energy sources are also constantly developing. Western developed countries such as Germany and the United States have been developing new fuels for diesel engines and gasoline engines since 1931. Especially in Germany, the current ratio of new fuels to traditional petroleum fuels has accounted for as much as 71%. However, its main development and utilization of biological raw materials, that is, plant and animal oils, have led to rising levels of edible oils, and The process is more complicated and the cost is higher. After entering the 21st century, people continue to deepen the research and development of low-cost and easy-t...

Problems solved by technology

However, due to the inherent characteristics of methanol itself, the proportion of methanol in the fuel is low. The synthetic fuel for diesel engines with methanol as the main raw material proposed in many technical solutions has a common difficulty: because of the low boiling point of methanol, When the temperature is high, it will cause the steam pressure to rise. Whether it is a rotary steam distribution device or a cross steam distribution device, it is easy to make the mixed steam too thin, resulting in air resistance, so that the engine cannot work normally and the utilization rate is not high. Therefore, how It is imperative to make full use of methanol to develop a fuel that is completely suitable for internal combustion engines to replace traditional petroleum energy
