Problems solved by technology

These formulas can solve the methanol-diesel miscibility problem to a certain extent, but there are still problems such as easy layering, insufficient mutual solubility and clarity, or low cost performance.
[0007] The common methanol or ethanol modified fuel oils currently on the market generally have the defect of low calorific value; the biodiesel usually referred to mostly refers to methyl oleate or a mixture of methyl oleate and petrochemical diesel, which has a high freezing point , high cold filter point, strong corrosion and insufficient cost performance

preparation example Construction

[0093] The preparation method of multivariate biofuel oil is as follows:

[0094] 1) Adjust the hydrophilic-lipophilic balance value of the surfactant to 10-14, and then fully mix it with n-butanol and water, or fully mix it with n-butanol;

[0095] The mixture obtained in step 1), oleic acid, methanol-modified complex and modified additives are uniformly mixed to prepare bio-fuel.

[0096] For example, add oleic acid step by step to the mixture obtained in step 1), and then mix it with the methanol-modified complex; or mix the oleic acid and the methanol-modified complex, and then mix it with the mixture obtained in step 1); or Add oleic acid to the methanol-modified complex and the mixture obtained in step 1), and then mix the two parts of the mixture evenly. Then add the modified additives and mix thoroughly.

[0097] The preferred preparation method of multivariate biofuel oil is as follows:

[0098] 1) Adjust the hydrophilic-lipophilic balance value of the surfactant to ...

Abstract

The invention provides multicomponent formula combined biological fuel oil and a preparation method thereof. Per 100 parts by weight of the multicomponent formula combined biological fuel oil comprise, in parts by weight, no more than 85 but larger than zero part of a methanol modified composite substance, 5-70 parts of oleic acid, 5-50 parts of n-butanol, 1-8 parts of a surfactant and 1-15 parts of a modified additive; and 0-45 parts by weight of industrial purified water can be added according to specific application. The multicomponent biological fuel oil has the performances similar to those of petrochemical diesel oil and can be mixed with common petrochemical diesel oil according to random ratios or a certain ratio for use, and the multicomponent biological fuel oil has the advantages of high fuel value, high flash point, low condensation point, low cold filter plugging point, low corrosivity, less discharge and low cost.

Description

technical field [0001] The invention relates to the field of fuel oil, in particular to a biofuel oil using multi-component formula combination and a preparation method thereof. Background technique [0002] my country is short of oil and gas, relatively rich in coal resources, and has a wide source of coal-based alcohol ether fuels. Substituting superior alcohol ether resources for petroleum resources, or using alcohol ether fuels and petroleum mixtures to replace petroleum resources, is beneficial to the ecological environment and promotes economic growth. Sustainable development, and can create new economic growth points. [0003] Many countries have promoted ethanol gasoline. The amount of ethanol added to petrochemical gasoline is generally 10-15%. However, since ethanol is mainly derived from crops, its promotion faces many problems such as cost and food safety. Therefore, in recent years, it has focused on promoting the addition of methanol. The main source of methano...
