Embodiment 1

[0024] (1) Preparation of Yuanbao Maple Oil:

[0025] Shelling: Control the moisture content of Acer truncatum seeds in the range of 8-12% (moisture adjustment is the key to ensure the yield), and enter the special shelling machine for Acer truncatum seeds for shelling treatment. After processing, the shells are selected by winnowing After the bene is separated, the Yuanbao Fengren is obtained.

[0026] Oil extraction: Adjust the moisture content of the peeled and separated Acer truncatum kernels to control the moisture content in the range of 8-10%. Use a 90-type press for oil extraction, and the oil yield is over 85%.

[0027] (2) Transesterification and supplementary esterification: Mix 100 parts of Acer truncatum oil with 40 parts of anhydrous methanol and 2 parts of sodium hydroxide, and reflux and esterify on a constant temperature water bath at 70°C. The stirring speed is about 60 rpm, reaction time After 2 hours, add 6 parts of concentrated sulfuric acid and continue the r...

Embodiment 2

[0032] (1) Preparation of Acer truncatum oil: the same as in Example 1.

[0033] (2) Transesterification and supplementary esterification: Mix 100 parts of Acer truncatum oil with 35 parts of anhydrous methanol and 2 parts of potassium hydroxide, and reflux and esterify on a constant temperature water bath at 75°C. The stirring speed is about 60 rpm, reaction time For 2.5 hours, add 5 parts of concentrated sulfuric acid and continue the reaction for 2.5 hours. After the reaction, wash with water to remove by-products.

[0034] (3) Alkali refining: Add 0.08% of its weight and 5% sodium carbonate solution to the reaction product. After adding it at 70°C, the temperature is raised to 90°C at a rate of 1°C / hour, and the temperature is increased while stirring. Keep the temperature at 90°C for 3 hours, the stirring speed is 50 / min in the mixing and heating stage, and 15r / min in the heat preservation stage. The soap particles are completely separated by standing precipitation, washing w...

Embodiment 3

[0038] (1) Preparation of Acer truncatum oil: the same as in Example 1.

[0039] (2) Transesterification and supplementary esterification: Mix 100 parts of Acer truncatum oil with 40 parts of anhydrous methanol and 1.5 parts of sodium hydroxide, and reflux and esterify on a constant temperature water bath at 72°C. The stirring speed is about 60 rpm and the reaction time After 2 hours, add 5 parts of concentrated sulfuric acid and continue the reaction for 2.5 hours. After the reaction, wash with water to remove by-products.

[0040] (3) Alkali refining: Add 0.1% of its weight and 4% sodium hydroxide solution to the reaction product. After adding it at 70°C, the temperature is increased to 90°C at a rate of 1°C / hour, and the temperature is increased while stirring. Keep the temperature at 90°C for 8 hours, the stirring speed is 60r / min in the mixing and heating stage, and the stirring speed is 20r / min in the heat preservation stage. The soap particles are completely separated by st...

Abstract

This invention relates to a method for preparing biodiesel oil from Acer truncatum seeds. The method comprises: (1) preparing Acer truncatum oil; (2) performing interesterification and supplementary esterification reactions; (3) refining with alkali; (4) flash-evaporating the crude methyl ester layer under 1000-2000 Pa for dehydration, and collecting the 135-220 deg.C fraction under 1-200 Pa to obtain biosiesel oil. The method avoids edible vegetable oils such as rapeseed oil and soybean oil as the raw materials, and has such advantages as abundant raw materials, simple process, and high yield.

Description

Technical field [0001] The invention relates to the technical field of biodiesel preparation technology, in particular to a method for preparing biodiesel from Acer truncatum seeds. Background technique [0002] At present, the raw materials for the production of biodiesel in China are different, most of which are the by-products of edible vegetable oils and fats such as rapeseed oil and soybean oil. At the current stage, the use of edible vegetable oils such as rapeseed oil and soybean oil as raw materials for production is a seizure of food from the population, which is a project not supported by the state; while the by-products remaining after oil processing are used as raw materials, the source of raw materials is very limited . The production of biodiesel from woody oil plants is the direction of biodiesel development. Woody oil plants include jatropha, pistacia, tung tree, Wenguang fruit tree, and Acer truncatum, but most of them are still in the re...
