Gasohol

from Wikipedia, the free encyclopedia

Gasohol is a mixture of nine parts gasoline and one part alcohol ( ethanol or methanol ). In some countries that do not have their own oil deposits, gasohol is used to reduce the cost of gasoline as a vehicle fuel. The raw materials for making methanol are coal and organic waste, especially wood waste products, while ethanol can be distilled from grains, sugary or any starchy plants.

Gasoline-alcohol mixtures were sometimes used in Europe when petroleum was scarce. Gasoline-alcohol blends such as Alcolene , Discol and Agrol were sold in the US in the 1930s when farmers tried to find other outlets for their products because of falling grain prices. Similar products were developed at the same time in Brazil, Cuba ( Espiritu ), the Czechoslovak Republic ( Dynakol ), Hungary ( Moltaco ), Sweden ( Lattbentyl ) and other countries. But they couldn't prevail against the cheaper gasoline. The oil shortage in the 1970s led to a renewed interest in alcohol mixtures, which intensified in 1985 when it was suggested that leaded petrol should be banned by the late 1980s at the latest. Gasohol is more expensive than petrol almost everywhere, but it is at least partially important as a renewable raw material. It can be used without changing a car's carburetor or ignition timing and has a slightly higher octane rating than regular unleaded gasoline. Only the fuel lines may need to be upgraded, i.e. replaced, because of the solvent properties of the alcohol.

Gasohol corresponds to the ethanol fuel E10 with 10% ethanol .
