Embodiment 1

[0038] Such as figure 1 As shown, the present embodiment provides a method for preparing biodiesel from apricot oil, which is prepared by the following steps:

[0039] 1) adding the adsorbent to 100 parts by weight of the apricot oil from which solid impurities have been removed, adding 5 parts by weight of the adsorbent, performing adsorption refining, removing phospholipids and free fatty acids, and obtaining 97 parts by weight of refined apricot oil;

[0040] The adsorbent is composed of hydrophobic adsorbent, hydrophilic adsorbent and alkaline adsorbent made of silica gel or activated carbon, and the weight ratio of the three is 12:1:10. The basic adsorbent is silica gel or activated carbon loaded with NaOH, and the loading of strong alkali is 4%.

[0041] 2) Mix the refined apricot oil with methanol and 0.4 parts by weight of NaOH catalyst, stir, and carry out the first reaction. The reaction temperature is 55°C, the pressure is normal pressure, and the molar ratio of ap...

Embodiment 2

[0047] Such as figure 1 As shown, the present embodiment provides a method for preparing biodiesel from apricot oil, which is prepared by the following steps:

[0048] 1) adding the adsorbent to 100 parts by weight of the apricot oil from which solid impurities have been removed, adding 3 parts by weight of the adsorbent, performing adsorption refining, removing phospholipids and free fatty acids, and obtaining 98 parts by weight of refined apricot oil;

[0049] The adsorbent is composed of hydrophobic adsorbent, hydrophilic adsorbent and alkaline adsorbent made of silica gel or activated carbon, and the weight ratio of the three is 5:1:3. Alkaline adsorbents loaded with Na 2 CO 3 Silica gel or activated carbon with a strong base loading of 7%.

[0050] 2) Mix the refined apricot oil with methanol and 0.5 parts by weight of NaOCH 3 The catalysts are mixed, stirred, and the first reaction is carried out. The reaction temperature is 50°C, the pressure is normal pressure, the...

Embodiment 3

[0056] Such as figure 1 As shown, the present embodiment provides a method for preparing biodiesel from apricot oil, which is prepared by the following steps:

[0057] 1) adding the adsorbent to 100 parts by weight of apricot oil from which solid impurities have been removed, adding 10 parts by weight of the adsorbent, performing adsorption and refining, removing phospholipids and free fatty acids, and obtaining 97 parts by weight of refined apricot oil;

[0058] The adsorbent is composed of hydrophobic adsorbent, hydrophilic adsorbent and alkaline adsorbent made of silica gel or activated carbon, and the weight ratio of the three is 3:1:20. The alkaline adsorbent is silica gel or activated carbon loaded with KOH, and the loading of strong alkali is 10%.

[0059] 2) Mix the refined apricot oil with methanol and 0.3 parts by weight of KOH catalyst, stir, and carry out the first reaction. The reaction temperature is 65°C, the pressure is normal pressure, and the molar ratio of ...

Abstract

A technical problem to be solved is providing a method for preparing biodiesel by using ansu apricot oil. The method comprises the steps of adsorption refining of ansu apricot oil as a raw material, primary esterification, settlement separation, secondary esterification, settlement separation, water washing and drying to prepare the biodiesel. The biodiesel produced by adopting the method accords with prescriptions of national standard GB / T20828, and has high quality; the method adopting the adsorption refining to refine the ansu apricot oil has the advantages of simple operation, low loss, no consumption of chemicals, and no emission of three wastes; and a two-step ester interchange reaction technology is adopted, and glycerin is separated between the two steps of the ester interchange reaction technology, so reaction raw materials and an intermediate product are deeply converted, and the product quality is good.

Description

technical field [0001] The invention relates to the technical field of biodiesel preparation technology, in particular to a method for preparing biodiesel from apricot oil. Background technique [0002] Biodiesel is a fatty acid ester obtained by transesterification (alcoholysis) of vegetable oil or animal fat with low-carbon alcohols (methanol, ethanol, etc.). Its performance is similar to that of petroleum diesel, and it is better and cleaner than petroleum diesel. [0003] The key to the development of biodiesel lies in the supply of oil raw materials. All countries in the world develop biodiesel based on the advantages of their own oil resources. For example, the raw material of the United States, Brazil and Argentina is genetically modified soybean oil, the raw material of double-low rapeseed oil is used in the European Union, and the raw material of Malaysia and Indonesia is palm oil. my country has a large population, and the production and sales of edible oil are se...
