Problems solved by technology

[0002] Ordinary diesel is a non-renewable energy. With the progress of human society, it is gradually being consumed. At the same time, the combustion rate of ordinary diesel is not high, and the heat of combustion is insufficient. Some fuels contain too much water, which is easy to cause corrosion of the engine and incomplete combustion. After burning, many residues will be produced, which will pollute the environment

Embodiment 1

[0009] Example 1. The biodiesel of the present invention is made according to the following steps:

[0010] a. Add 30 liters of vegetable oil to the condenser, then add 50 liters of ethanol, then add 10 liters of solvent oil, and then add 10 liters of sodium hydroxide;

[0011] b. The mixture in the condenser is heated to 60°C, and the constant temperature reaction is performed for three hours;

[0012] c, add 3 liters of sodium glycolate in the mixture obtained after distillation;

[0013] d. The mixture in c is centrifuged to obtain a finished product.

Abstract

The invention relates to a method for manufacturing biodiesel from vegetable oil. The method particularly comprises the following steps that: the vegetable oil is used to form fatty acid ester under the action of an acid catalyst or a basic catalyst through reacting with low molecular alcohol; and the biodiesel is obtained by using a glycollic acid substance through centrifugal separation. The method can reduce the discharge degree of atmospheric environmental pollutants, and the biodiesel belongs to a renewable and available resource.

Description

technical field [0001] The invention relates to diesel oil used in internal combustion engines and a production method thereof, in particular to a production technology for producing biodiesel by using vegetable oil. Background technique [0002] Ordinary diesel is not a renewable energy source. With the progress of human society, it is gradually being used up and waiting to be exhausted. At the same time, the combustion rate of ordinary diesel is not high, the combustion heat is insufficient, and some fuels have too much water content, which is easy to cause engine corrosion and incomplete combustion. After burning, many residues will be produced, which will pollute the environment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a production method for producing biodiesel by using vegetable oil with high combustion rate, sufficient combustion heat, low water content and environmental protection of combustion residues. [0004] In the...
