Example Embodiment

[0019] Example 1

[0020] Mineral diesel 45%, vegetable oil 30%, methanol 18%, sodium lauryl sulfonate 2.0%, OP emulsifier 1.5%, triethanolamine 2.0%, naphthenic acid 1.49%, biological complex enzyme 0.01%, the percentage is Mass percentage.

[0021] The preparation method is: as shown in the figure, mix vegetable oil with methanol, sodium lauryl sulfonate, OP emulsifier, and triethanolamine according to the above mass percentage; slowly pour the mixture into the mineral diesel under stirring At the same time, add naphthenic acid and bio-complex enzymes according to the mass percentage requirements, stir and mix thoroughly to prepare -10# blended biodiesel that can be stored for more than half a year without stratification.

Abstract

The invention discloses a number 10 proportional bio-diesel, which comprises the following substances in percentage by weight: 45 to 60 mineral diesel, 20 to30 plant oil, 10 to 15 methanol, 1.0 to 3.0 naphthenic acid, 1.0 to 3.0 OP emulsifier, 0.8 to 2.0 sodium dodecyl sulfate, 0.5 to 2.0 triethanolamine and 0.01 to 0.03 bio-enzyme. The preparation method comprises the following steps that: the plant oil is uniformly mixed with the methanol, the OP emulsifier, the sodium dodecyl sulfate and the triethanolamine according to the above mass percent, naphthenic acid and bio-enzyme are added to beadequately mixed, and the mixed solution is slowly poured into the mineral diesel under the mixing condition to obtain the number 10 proportional bio-diesel. The proportional bio-diesel has advanced process, environmental protection and stable product performance, is free from liquating grease and methanol after being stored for more than half year at the temperature of minus 10 DEG C, is transparent and stable, and can reach the standard of the number 10 bio-diesel in GB/T20828 - 200 standard. The proportional bio-diesel is proved in the industrial boiler and diesel engine rack test that: the diesel is stable to store and to burn, has high heat value, and is normal to be atomized by oil path and nozzle. The engine is stable to run.

Description

technical field [0001] The invention belongs to the technical field of biodiesel, and mainly relates to a -10# blended biodiesel and a preparation method thereof. Background technique [0002] With the increasingly tense energy supply situation, the research on biodiesel is deepening day by day, and five related methods for preparing biodiesel have been reported successively, namely dilution, microemulsion, pyrolysis, transesterification and biotechnology methods. At present, the chemical transesterification method is mainly used, but the biodiesel synthesis by the chemical transesterification method has the following disadvantages: the process is complicated, the alcohol must be excessive, the subsequent process must have a corresponding alcohol recovery device, the energy consumption is high, the cost is high, and the color is deep. Unsaturated fatty acids are prone to deterioration at high temperatures. In order to solve the above problems, people began to study the synt...
