Problems solved by technology

[0003] At present, there are few researches on the condensation technology of biodiesel at home and abroad, and most of the previous studies focus on the low-temperature fluidity of biodiesel produced by selecting one or several specific crops, such as peanut oil, corn oil, and waste oil, etc., resulting in The low-temperature fluidity law of biodiesel obtained has poor general applicability and strong limitations, and is not easy to be extended to other types of biodiesel

Abstract

The invention discloses a simulating biodiesel, a preparation method thereof and a method for testing the affection of each component in the simulating biodiesel on the condensation point of the simulating biodiesel by utilizing the single-factor method. The simulating biodiesel consists of 0.5 to 2 percent by weight of methyl myristate, 20 to 30 percent by weight of methyl palmitate, 5 to 10 percent by weight of methyl stearate, 35 to 45 percent by weight of methyl oleate, 18 to 25 percent by weight of methyl linoleate and 1 to 3 percent by weight of methyl linolenate. The preparation method for the simulating biodiesel includes the following steps: each single fatty acid methyl ester is weighed into a beaker, the beaker is then placed into a constant-temperature water bath, and after stirring, the simulating biodiesel is obtained. The reliability and the general applicability of the low-temperature fluidity of reached biodiesels are enhanced, and the process of researching the low-temperature fluidity of biodiesels is simplified. The conditions in the process of preparing the simulating biodiesel are mild, the simulating biodiesel is environment-friendly, the process is simple and easy to control, moreover, the materials can be easily obtained, and the implementation is easy.

Description

technical field [0001] The invention relates to a method for using simulated biodiesel to test the influence of its components on its condensation point, and belongs to the technical field of biodiesel decondensation. Specifically, it relates to a simulated biodiesel and a preparation method, and uses a single factor method to test the influence of each component in the simulated biodiesel on its condensation point. Background technique [0002] Biodiesel, fatty acid methyl ester, also known as Sunfuel, is an oxygen-containing clean fuel based on renewable resources (such as rapeseed oil, soybean oil, corn oil, cottonseed oil, peanut oil, sunflower oil, palm oil, coconut oil, recycled cooking oil and animal oil, etc.) as raw materials, with performance similar to petroleum diesel. As a high-quality diesel substitute, biodiesel is an environmentally friendly green fuel. [0003] At present, there are few researches on the condensation technology of biodiesel at home and abr...
