Liquid cleaning environmental-protection diesel fuel and preparation method thereof

Abstract

The present invention relates to an efficient environmental-protection liquid fuel, particularly to a liquid cleaning environmental-protection diesel fuel and a preparation method thereof. The liquid cleaning environmental-protection diesel fuel is prepared from the following raw materials according to a certain weight ratio, wherein the optimal weight ratio of oleic acid to methanol to methylal to water to ammonia water to n-butanol to dimethyl carbonate is 40%:20%:10%:8%:8%:6.5%:7.5%. The preparation steps comprise: 1, selecting methanol, methylal and water, pouring into oleic acid to mix, and then adding ammonia water; 2, completely mixing the components in the step 1, and carrying out a static reaction for 5 min to spare; 3, selecting n-butanol and dimethyl carbonate, and carrying out a mixing reaction to spare; 4, adding the mixture obtained in the step 2 to the mixture obtained in the step 3, carrying out slight stirring for 10-20 min, taking 50% of the obtained solution to spare; and 5, mixing any one material selected from 0# international diesel fuel, -10# international diesel fuel and -20# international diesel fuel and the solution, and carrying out slight stirring for 10-20 min to obtain the liquid cleaning environmental-protection diesel fuel. The liquid cleaning environmental-protection diesel fuel has characteristics of strong power, low emission, wide application range and long shelf life.

Description

technical field [0001] The invention relates to a liquid environment-friendly fuel, in particular to a liquid clean environment-friendly diesel oil and a preparation method thereof. Background technique Due to the increasingly tense world energy and the continuous strengthening of environmental protection awareness, considering China's energy strategy in combination with the world's energy situation and its own country, the promotion of ethanol gasoline can improve the current shortage of oil resources in my country. Gasoline comes from non-renewable oil resources. Ethanol is derived from renewable plant resources. The use and promotion of ethanol gasoline can alleviate China's energy shortage and continue the history of the oil age. Based on the analysis of existing resources and utilization conditions, oil has only about 40 years of life left in the world. Energy experts believe that China's promotion of the use of ethanol gasoline is a strategic choice for a large energ...

Problems solved by technology

However, adding these co-solvents to diesel oil can not solve the problem of poor miscibility between diesel oil, methanol and ethanol, and will also lead to increased product prices, increased emissions of N-containing wastes, and environmental pollution.
