Biodiiselkütuse

Biodiiselkütuse is a type of diesel fuel derived from vegetable oils or animal fats. It is considered a renewable energy source because the raw materials used to produce it can be replenished naturally. The production process typically involves a chemical reaction called transesterification, where triglycerides from the oil or fat are reacted with an alcohol (commonly methanol or ethanol) in the presence of a catalyst. This process separates the glycerol from the fatty acid methyl esters, which are the primary components of biodiiselkütuse. Biodiiselkütuse can be used in diesel engines either in its pure form (B100) or blended with conventional petroleum-based diesel fuel. Common blends include B5 (5% biodiiselkütuse and 95% petrodiisel) and B20 (20% biodiiselkütuse and 80% petrodiisel). The use of biodiiselkütuse can offer environmental benefits such as reduced net carbon emissions, as the carbon dioxide released during combustion is theoretically offset by the carbon dioxide absorbed by the plants during their growth. It also tends to have lower levels of sulfur and particulate matter compared to petrodiisel. However, factors like land use for feedstock cultivation, energy input for production, and potential impacts on food prices are also important considerations.
