Embodiment Construction

[0016] The following examples describe the present invention in more detail:

[0017] Using lard as raw material, add 450kg of lard into the alcoholysis kettle, slowly raise the temperature to 40-45°C, add 100kg of methanol into the alcoholysis kettle, and dissolve 5kg of potassium hydroxide into the alcoholysis kettle before adding it into the alcoholysis kettle During the process, the temperature was raised to 67-73°C with stirring, and the temperature was maintained for 150 minutes for alcoholysis. During the alcoholysis process, methanol was refluxed. After the end of the alcoholysis, the temperature was slowly lowered to 50°C, the stirring was stopped, and the material was transferred to the separation tank. After static stratification, separate the upper light phase from the lower heavy phase, transfer the light phase to a water washing tank, add 250kg of cold water to stir and wash, separate the water washing liquid after standing still, and wash with water continuously ...

Abstract

The present low-cost preparation method with animal oil for biological diesel fuel with fatty acid methylate as essential component comprises: with KOH as catalyst, adding the material and methanol into the alcoholysis kettle by weight ratio as 4-6:1; heating for alcoholysis while stirring; stopping stirring, cooling slowly, and transferring the material to separating tank for static stratification; pouring the top light phase into washing kettle, dewatering in vacuum dry kettle; finally, cooling for the product, which has flash point as 4Deg, cetane number as 49 and closed flash point as 181Deg, and can replace or dope by any proportion with the common diesel fuel.

Description

(1) Technical field [0001] The invention relates to a method for preparing fuel, in particular to a method for preparing biodiesel by using animal oil as a raw material. (2) Background technology [0002] The main component of biodiesel is "fatty acid methyl ester". As a substitute for petrochemical diesel, it is mainly a clean and environmentally friendly fuel made from animal and vegetable oils. Since the 1970s, especially after 1991, on the one hand, the price of oil has continued to rise, while oil resources have been depleted day by day, and the whole world is facing a crisis of energy shortage. On the other hand, with the continuous improvement of people's living standards and the continuous enhancement of environmental awareness, they have gradually realized the seriousness of air pollution caused by petroleum fuels, especially "photochemical smog" that has caused great harm to the human body, thus forcing humans to seek New energy - "clean fuel" to replace petroleum...
