Biodiesel represents methyl (less often ethyl) ethers of fatty acids and is a perspective substitute for traditional hydrocarbon fuel. Raw materials for production of biodiesel are vegetable oils, food-industry wastes and waste oils used for cooking.
Benefits of Biodiesel
- High cetane number (average 45,8-56,9 units)
- High flash point (above +100)
- Good lubricating property
- Absence of sulfur and aromatic hydrocarbons
- Low toxicity of emissions
- Virtually complete biodegradability (99%
biodiesel are destroyed in water or soil for 28 days)
- Zero balance of greenhouse gases
Features of consumption of biodiesel
The main consumers are Germany, Great Britain, France, Austria, Spain
National biodiesel programs are started more than in 20 countries
Three of four liters of diesel fuel sold in EU contain biodiesel. The obligatory share of biofuel is 5,75 % in 2010, 20 % by 2020
