Embodiment 1

[0019] Embodiment 1 Get each raw material by following weight additive: 40kg dimethyl carbonate, 12kg potassium hydroxide, 0.75kg etherified corn fusel oil, 8.25kg carbon number is the fatty alcohol of 15, the oxirane of 6kg, 30kg ethyl alcohol Glycol monomethyl ether. Mix etherified corn fusel oil with fatty alcohol, then mix the resulting mixture with ethylene oxide, then heat to 80°C±5°C, keep at this temperature for 2 hours, and then add potassium hydroxide to it And mix homogeneously to obtain product (a), in addition, dimethyl carbonate and ethylene glycol monomethyl ether are uniformly mixed to obtain product (b), and finally product (a) and product (b) are uniformly mixed to obtain the biodiesel additive .

Embodiment 2

[0020] Example 2 The raw materials were taken according to the following weight additives: 40 kg of rapeseed crude oil produced in Anhui Province, 5 kg of the additive provided in Example 1 and 55 kg of diesel oil, and the three were mixed uniformly to obtain diesel oil with a cetane number of 48 or more.

[0021] The test data of various technical indicators of the high cetane number and the comparison data of the existing 0# diesel oil are shown in Table 1.

Abstract

This invention discloses an additive for producing biosiesel oil from animal and plant oils. The additive is prepared from: dimethyl carbonate 35-45 wt.%, KOH 10-15 wt.%, catalyst 0.75-1.25 wt.%, saponification inhibitor 8.25-13.75 wt.%, chain-breaking agent 6-10 wt.%, and ethylene glycol monomethyl ether 30-40 wt.%. The obtained biodiesel oil comprises animal and plant oils, diesel oil and additive at a weight ratio of (30-60) :( 38-65) :( 2-5).

Description

technical field [0001] The invention belongs to the technical field of fuel oil processing, and in particular relates to an additive for producing biodiesel from animal and vegetable oils by a direct method and biodiesel prepared by using the additive. Background technique [0002] For example, to process vegetable oil into biodiesel, the traditional esterification processing technology is currently used at home and abroad, which requires methanol or ethanol as the raw material for esterification, and acid or alkali as the catalyst. Produced fatty acid methyl ester or fatty acid ethyl ester——biodiesel to replace diesel oil. When biodiesel is produced, non-standard glycerin and acid-containing oily wastewater are also produced. Mass production requires a large amount of wastewater to be treated, and the production cost is high. The environment is polluted. my country is a big oil-consuming country, and the demand for diesel oil is very tight. How to effectively utilize renew...
