Bioethanol - product information
Bioethanol is ethyl alcohol, a fuel made primarily from wheat, and other grains. From a global point of view, bioethanol made from crops is currently the most expanded organic fuel for transportation sector. It is used either for octane enhancement or fuel emission quality enhancement. Bioethanol has significant influence on reducing of CO2 emissions in air.
Bioethanol can be mixed directly or indirectly with fossil fuels. Ethanol can be directly blended at any percentage to gasoline, but the more typical blend is a 10% to 90% ratio of ethanol to gasoline (E10). Another common blend is the 85% ethanol to 15% gasoline (E85). ED95 blend (blend with 90% of ethanol and 10% of cosolvents) is considered as 100% renewable fuel and is at present being used mainly for applications in the public transport.
Adding 10% blend ethanol to gasoline boosts its octane by about 3 points, effectively creating premium gas out of regular gas. Further such low blend doesn´t require any changes to common car engines.
Ethanol is also water soluble, non-toxic and biodegradable, meaning it poses no pollution threat to water supplies nor the environment. The use of ethanol as an automobile fuel is not something new. In the United States, Henry Ford's worldwide famous model "T" was built to operate using either gasoline or ethanol already back then. For several reasons, primarily the discovery of cheap sources of domestic oil and gasoline, ethanol dropped out of favor for use as a fuel early in the 20th century. With the first significant oil crisis of the 1970's, interest in ethanol production began to increase again in popularity. There has been a surge of ethanol production facilities since that time, the biggest boom is now being experienced in the North and South American continent (USA and Brazil), but recently also in Europe.
