Biofuel oil and its prepn process

Abstract

The present invention discloses one kind of biofuel oil and its preparation process. The biofuel oil consists of diesel oil, fatty acid, water, modifier A and modifier B in certain weight proportion. Its preparation process includes the first mixing diesel oil, fatty acid and water and heating to 50-90 deg.c; and the subsequent adding modifier A and modifier B and stirring for 5-10 min to obtain the biofuel oil product. The biofuel oil of the present invention has low cost, no pollution, environment friendship, and other advantages.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a biofuel and a preparation method thereof. Background technique [0002] As an important petroleum refining product, diesel oil occupies a high share in the fuel structure of various countries. It is the main power fuel for many large vehicles (such as trucks, internal combustion engines and generators, etc.), and has the advantages of high power and low price. With the acceleration of dieselization of vehicles worldwide, the demand for diesel will increase in the future. The depletion of petroleum resources and the improvement of people's awareness of environmental protection have greatly promoted the development of diesel alternative fuels in countries around the world. [0003] There are also many problems in the application of diesel oil, such as low combustion efficiency, serious air pollution, a large amount of particulate dust, and high carbon dioxide emissions.

AI Technical Summary

Problems solved by technology

[0005] However, chemical synthesis of biodiesel has the following disadvantages: complex process, deep color, and because the unsaturated fatty acids in fat are easy to deteriorate at high temperature, the esterification products are difficult to recycle, the cost is high, and waste lye is discharged during the production process, etc.

[0006] At present, the main problem of biodiesel is the high cost. According to statistics, 75% of the production of diesel from biodiesel is the cost of raw materials. Therefore, the key to the practical use of biodiesel is to use cheap raw materials and improve the conversion rate to reduce costs.
