Synthetic biodiesel and preparation method thereof

Abstract

The invention discloses synthetic biodiesel and a preparation method thereof. The biodiesel is prepared from the following components in percentage by weight: 50 to 70 percent of acidified oil, 10 to 20 percent of methanol, 10 to 38 percent of desulfurized heavy benzol, 1 to 5 percent of light oil and 0.3 to 0.8 percent of catalysis additive. The synthetic biodiesel has the advantages of high oxygen content, full combustion, low sulfur content, low corrosion, no freezing at the temperature of below 4DEG C, high fluidity at low temperature, and light exhaust emission pollution.

Description

technical field [0001] The invention relates to the technical field of biodiesel that can replace petrochemical diesel, in particular to a synthetic biodiesel and a preparation method thereof. Background technique [0002] At present, diesel oil, as a fuel oil, is widely used in various fields such as automobiles, trucks, and boilers. With the continuous increase in energy consumption of crude oil, crude oil resources have been over-exploited, and oil resources are becoming less and less. Faced with energy shortage and shortage, the price of crude oil keeps rising. Moreover, the diesel oil in the prior art has a long CH chain, does not contain oxygen, has incomplete combustion, has many pollutants, has a high sulfur content, is highly corrosive, and is easy to increase viscosity and freeze below 4°C, resulting in poor fluidity and heat. Low value, poor dynamic performance and other deficiencies. Contents of the invention [0003] The present invention aims at the above-m...
