Abstract

The invention provides a biodiesel-based alcoholic fuel oil, which consists of the following substances in percentage by mass: 20 to 50 percent of refined biodiesel, 40 to 80 percent of industrial methanol and 5 to 30 percent of additive, wherein the additive comprises 5 to 20 percent of solvent aid, 1 to 15 percent of cosurfactant, 0.2 to 2 percent of stabilizer and 0.1 to 1 percent of corrosion inhibitor. A preparation method comprises the following steps of: mixing the substances in percentage by mass, and stirring the mixture uniformly at normal temperature to obtain the fuel oil. The fuel oil has the advantages of low cost, high heat value and stable performance; the preparation method has the advantages of simple process, convenience and safety of use and good adaptability to the boiler; and compared with diesel oil, the fuel oil is economic and energy-saving, has low environmental pollution, is regenerative energy, and can be used as commercial oil for great popularization and use.

Description

technical field [0001] The invention belongs to the technical field of fuel oil mixing, and in particular relates to biodiesel-based alcohol-based fuel oil and a preparation method thereof. Background technique [0002] With the increasing global energy shortage and environmental deterioration, 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 widespread attention for its excellent environmental friendliness and renewability. It is a renewable energy source that is environmentally friendly and safer to use, transport and store. 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 a...
