Example Embodiment

[0024] Example 1:

[0025] Add 200 kilograms of Aronia arborescens oil, 400 kilograms of bioethanol, and 150 kilograms of methyl tert-butyl ether into a reactor with a reflux device. Stir evenly, add 3 kilograms of potassium hydroxide-magnesium oxide solid base catalyst, and continue stirring. Form a suspension, heat to 50~70℃, reflux through the condenser, stir the reaction for 40~45 minutes, cool to room temperature, filter out the catalyst, and then add 150 kg of biodiesel, 50 kg of mixed fatty acid, 40 kg of acetone, and sulfuric acid. 3 kilograms of cerium ammonium, 2 kilograms of isopropyl hydrogen peroxide, 2 kilograms of polyvinyl succinimide, continue to stir and react for 20-30 minutes to prepare the biomass fuel oil. The test has a burning value of 10685 kcal / kg, a flash point of 63℃, and a wear scar diameter of 440mm by the HFRR test method.

Example Embodiment

[0026] Example 2:

[0027] Add 500 kilograms of catering industry waste oil, 100 kilograms of biobutanol, and 150 kilograms of diethoxymethane into the reaction kettle with a reflux device, stir evenly, add 10 kilograms of potassium carbonate-magnesium oxide solid base catalyst, and continue to stir to form The suspension is heated to 50~70℃, refluxed through the condenser, stirred and reacted for 70~75 minutes, cooled to room temperature, filtered to remove the catalyst, and then sequentially added 115 kg of commercially available biodiesel, 5 kg of stearic acid, and 100 petroleum ether Kilograms, 10 kilograms of ferrocene, 5 kilograms of hydrogen peroxide, 5 kilograms of tert-amylamine, and continue to stir and react for 20-30 minutes to prepare the biomass fuel oil. The experimentally measured combustion value is 10482 kcal / kg, the flash point is 61°C, and the wear scar diameter is 430mm by HFRR test method.

Example Embodiment

[0028] Example 3:

[0029] Add 396 kilograms of catering industry waste oil, 400 kilograms of methanol, and 50 kilograms of methyl tert-butyl ether into the reactor with a reflux device, stir evenly, add 1 kilogram of potassium hydroxide-calcium oxide solid base catalyst, and continue to stir to form The suspension is heated to 50~70℃, refluxed through the condenser, stirred for 20-25 minutes, cooled to room temperature, filtered to remove the catalyst, and then added 150 kg of commercially available biodiesel, 1 kg of ferrocene, and isopropyl 1 kilogram of hydrogen peroxide and 1 kilogram of polyvinyl succinimide, continue to stir and react for 20-30 minutes to prepare the biomass fuel oil. The experimentally measured combustion value is 10546 kcal / kg, the flash point is 62℃, and the wear scar diameter is 450mm by the HFRR test method.

Abstract

The invention relates to biomass fuel oil. The biomass fuel oil comprises the following components in percentage by weight: 10 to 15 percent of vegetable oil, 10 to 40 percent of bio-alcohol, 5 to 15 percent of bio-diesel, 0 to 5 percent of fatty acid, 5 to 15 percent of mutual solvent, 0 to 10 percent of combustion accelerant, 0.1 to 1 percent of solid base catalyst, 0.1 to 1 percent of combustion improver, 0.1 to 0.5 percent of oxygenate and 0.1 to 0.5 percent of detergent. A preparation method of the biomass fuel oil comprises the following steps of: a, adding and uniformly stirring the vegetable oil, the bio-alcohol and the mutual solvent in a reaction kettle, adding the solid base catalyst into the mixture and stirring the mixture to form suspension; and b, heating the suspension to 50 to 70 DEG C, making the suspension flow back through a condenser, stirring the obtained product for 10 to 90 minutes, cooling the product to the room temperature, filtering off the solid base catalyst, then sequentially adding the bio-diesel, the fatty acid, the combustion accelerant, the combustion improver, the oxygenate and the detergent and stirring and reacting the mixture for 20 to 30 minutes to obtain the biomass fuel oil. The biomass fuel oil provided by the invention has the advantages of high combustion value, high lubricating property and high flash point.
