Biodiesel originated in 1892 by German engineer Dr. Rudolf Diesel (1858-1913) and a peanut oil fuel compression ignitor. In 1895, Rudolf first proposed the use of animal and vegetable oils as raw materials to esterify with methanol or ethanol, and finally became a fuel for internal combustion engines. However, due to the abundant oil resources in the world and the large supply of surplus petrochemical diesel, there is no contradiction between supply and demand. Therefore, Rudolf’s invention did not attract enough attention in society.
The systematic study of biodiesel began only after the oil crisis of the 1970s.
Due to the regenerative and environmentally friendly nature of biodiesel, it has attracted the attention of many developed countries in the world, especially those with poor resources. 80% of Brazilian oil in South America relies on imports. Therefore, Brazil is one of the countries that researched and first mastered the technology of converting vegetable oil into biodiesel and replacing petrodiesel with biodiesel. Brazil's annual production of biodiesel reaches 500,000 tons. There are currently four biodiesel plants in the United States with an annual production capacity of 300,000 tons. The EU uses rapeseed as a raw material for the production of biodiesel, with a total output of around 80% of the world. The European Union produces biodiesel mainly from Germany, France and Italy. Germany already has eight biodiesel plants with more than 300 biodiesel filling stations; the government has a production tax rate of 0%. In 2006, Germany's biodiesel production was 1 million tons, and Germany has completely replaced biodiesel with other petrochemical diesel fuels used in buses, taxis and construction and agricultural machinery. Japan's annual production capacity of biodiesel is 400,000 tons. Thailand uses palm oil and coconut oil as raw materials, and the annual production capacity of biodiesel is also 100,000 tons. Malaysia plans to build the world's first biodiesel plant with an annual output of 300,000 tons in Sabah, a palm-rich city. It will be the world's biodiesel plant in the future.
China's biodiesel research and development started relatively late. In the early 1980s, China Petrochemical Corporation allocated special funds for the project. A large number of basic experiments were carried out by Shanghai Internal Combustion Engine Research. The "Eighth Five-Year Plan" began in the 1990s. The Ministry of Science and Technology begins research on biofuels by the state
The Ministry of Science and Technology has listed biofuel research as a major scientific and technological project. Now it has formed biodiesel production technology and mass production plants with independent intellectual property rights: Yongshun Tianze Bioenergy Co., Ltd. and Hunan Bioenergy Co., Ltd.
In 2007, the annual output of biodiesel in China has exceeded 2 million tons. As an alternative energy source for petrochemical diesel, biodiesel will definitely show an increasing trend. However, since the production cost of biodiesel is 60%-70% of the cost of raw materials, the cost of raw material resources plays a decisive role in the price of biodiesel. Therefore, the use of cheap raw materials, reducing energy consumption, and reducing costs are key factors. At the same time, China does not use a large amount of soybeans, corn and other food crops as raw materials, and does not use a large amount of edible vegetable oil as a raw material to produce biodiesel. We must adhere to the principle of "not fighting for food, not fighting for food." Work hard on raw materials and production processes. Moreover, in the production of biodiesel, it is also possible to produce some value-added fine chemical products. In this way, the cost is further reduced and the overall economic benefits of production can be improved.
