Alcohol-based fuel oil and preparation method thereof

Abstract

Te invention relates to alcohol-based fuel oil and a preparation method thereof. The alcohol-based fuel oil comprises the following components in percentage by weight: 57.5%-67.5% of fuel oil, 10%-20% of fatty acid, 10%-20% of crude carbinol, 0.5%-1.5% of diethanol amine and 0.1%-1% of ethyl nitrate. The preparation method for the alcohol-based fuel oil comprises the following steps of: adding the 10%-20% of crude carbinol when the fuel oil, the fatty acid, the diethanol amine and the ethyl nitrate are mixed and heated up to 40 DEG C; and forming the clear fuel oil by high-speed shearing and stirring. The fuel oil is high in stability; the preparation method is simple; the fatty acid is utilized as an emulsifier, and the crude carbinol can be uses as a combustion improver and pour point reducer by virtue of the water-containing characteristics of the crude carbinol, so that the dosage of the dear additive is reduced and the production cost is reduced; moreover, the fatty acid is formed and processed by utilizing recycled cooking oil as well as waste acidifying plant oil as materials, so that the waste is recycled, and the resource utilization rate is high.

Description

technical field [0001] The invention relates to fuels, in particular to a biomass fuel oil and a preparation method thereof. Background technique [0002] With the deterioration of the environment and the shortage of energy, the development of fuels that can replace petroleum and the protection of the natural environment on which human beings depend have become serious problems facing human beings. Biodiesel has attracted people for its excellent environmental friendliness and renewability. It is widely concerned that it is a renewable resource, and its use, transportation and storage are safer. However, biodiesel has a high freezing point, its properties are easily affected by temperature, and its viscosity is higher than that of petrochemical diesel, which are not conducive to its popularization and application. [0003] Alcohol-based biofuel oil overcomes the above shortcomings. Under the action of co-solvent, a certain amount of alcohol is added to biodiesel to form a m...
