Description

technical field

[0001] The invention relates to a method for refining biodiesel, especially a method for removing soap and free glycerin in biodiesel. Background technique

[0002] Biodiesel is a renewable, environment-friendly energy source and a necessary supplement to petroleum diesel. In 2006, the EU's biodiesel production is expected to exceed 6.069 million tons, an increase of 91% over 2005. The EU plans to achieve biodiesel consumption accounting for 20% of total diesel consumption by 2020. my country is a country with insufficient oil production. In 2005, it imported 26.59 million tons of soybeans, and its per capita edible oil consumption was 15 kg, just reaching the world average level. At the present stage, my country's development of biodiesel industry cannot apply the model of the European Union and the United States to occupy a large amount of edible oil resources. A better way is to use acidified oil, hog oil, woody vegetable oil (such as jatropha seed oil)...
