Embodiment 1

[0015] Step 1, mix 10Kg of fatty alcohol polyoxypropylene ether, 14Kg of rosin, 5Kg of unleaded gasoline, 1Kg of fatty acid ammonium, 2Kg of tert-butyl peroxyacetate, 4Kg of phenylpropanol, 5Kg of oleic acid, and 3Kg of paraffin. After mixing evenly, heat Dissolve at 30°C, stir evenly, let cool to room temperature, and obtain the additive;

[0016] Step 2: Mix 20Kg of diesel oil, 10Kg of cracked kerosene, 10Kg of No. 70 gasoline, 40Kg of biodiesel, 2Kg of co-solvent, 2Kg of stabilizer, and additives. Yes; the amount of the additive is 0.5% by weight of the biodiesel; the diesel refers to No. 0 or No. 10 or No. 20 diesel.

[0017] The co-solvent is tert-butanol and the stabilizer is hydroxypropyl methylcellulose.

Embodiment 2

[0019] Step 1, mix 20Kg of fatty alcohol polyoxypropylene ether, 21Kg of rosin, 10Kg of unleaded gasoline, 3Kg of fatty acid ammonium, 3Kg of tert-butyl peroxyacetate, 7Kg of phenylpropanol, 7Kg of oleic acid, and 6Kg of paraffin. After mixing evenly, heat Dissolve at 40°C, stir evenly, let cool to room temperature, and obtain the additive;

[0020] Step 2. Mix 30Kg of diesel oil, 20Kg of cracked kerosene, 20Kg of No. 70 gasoline, 60Kg of biodiesel, 4Kg of co-solvent, 4Kg of stabilizer, and additives. Yes; the amount of the additive is 1% of the weight of the biodiesel; the diesel refers to No. 0 or No. 10 or No. 20 diesel.

[0021] The co-solvent is isoamyl alcohol and the stabilizer is carboxymethyl cellulose.

Embodiment 3

[0023] Step 1, mix 14Kg of fatty alcohol polyoxypropylene ether, 16Kg of rosin, 6Kg of unleaded gasoline, 2Kg of fatty acid ammonium, 2Kg of tert-butyl peroxyacetate, 5Kg of phenylpropanol, 6Kg of oleic acid, and 5Kg of paraffin. After mixing evenly, heat Dissolve at 35°C, stir evenly, let cool to room temperature, and obtain the additive;

[0024] Step 2. Mix 25Kg of diesel oil, 15Kg of cracked kerosene, 15Kg of No. 70 gasoline, 47Kg of biodiesel, 3Kg of co-solvent, 3Kg of stabilizer, and additives. Mix evenly, raise the temperature to 45°C, keep it warm for 2 hours under stirring, and let it cool down. Yes; the amount of the additive is 0.6% of the weight of the biodiesel; the diesel refers to No. 0 or No. 10 or No. 20 diesel.

[0025] The co-solvent is isobutanol and the stabilizer is hydroxypropyl methylcellulose.

Abstract

The invention relates to a preparation method of blend biodiesel, in particular relates to a blend biodiesel suitable for use in high and cold areas, and belongs to the technical field of fuels. The preparation method comprises the following steps: uniformly mixing fatty alcohol polyoxypropylene ether, rosin, lead-free gasoline, fatty acid ammonium, tert-butyl peroxyacetate, phenylpropanol, oleic acid and paraffin, then heating for dissolution, stirring uniformly, and cooling to room temperature to obtain an additive; and uniformly mixing diesel oil, cracked kerosene, 70# gasoline, biodiesel, a cosolvent, a stabilizer and the additive, then heating, keeping the temperature while stirring, and then cooling, wherein the diesel oil refers to 0#, 10# or 20# diesel oil. The condensation point of the biodiesel prepared by the method provided by the invention, compared with that of common biodiesel, is greatly reduced and can reach less than -10 DEG C, so that the biodiesel is suitable for use in the high and cold areas.

Description

technical field [0001] The invention relates to a method for preparing a blended biodiesel, in particular to a blended biodiesel suitable for use in alpine regions, and belongs to the technical field of fuels. Background technique [0002] With the acceleration of dieselization of vehicles worldwide, the demand for diesel is increasing, and the depletion of petroleum resources and the improvement of people's environmental awareness have greatly promoted the development of diesel alternative fuels in countries around the world. Biodiesel, also known as fatty acid alkyl ester, is obtained from vegetable oil, animal fat, waste cooking oil, etc. through transesterification with alcohols (methanol, ethanol), the most typical being fatty acid methyl ester. Biodiesel has the following characteristics: it is a renewable resource, which can alleviate the shortage of oil resources; promote the sustainable development of forestry and agriculture, increase farmers' income; effectively r...
