Bio Ethanol for automobile fuel

bensin hijauEthanol has powered automobiles for more than a century. Ford designed his model T for ethanol as a fuel. Gradually petroleum took over and became the dominating transport fuel. In the seventies Brazil adopted an ethanol strategy and today motor fuel grade ethanol (MFGE) is an extremely fast growing market worldwide.

Bioethanol is renewable, because it is made from glucose created in green plants by the sun, the so called photosynthesis:

(1) 6CO2 + 6H2O + sunshine ? C6H12O6 + 6O2
Sun energy transforms carbon dioxide (CO2) into glucose (C6H12O6). This glucose is transformed once again to ethanol (C2H6O) by classic yeast fermentation:
(2) C6H12O6 ? 2C2H6O + 2CO2 + heat
Heat is released calling for cooling of the fermentation vessels and heat is released again when the ethanol is burned in the combustion engine:
(3) C2H6O + 3O2 ? 2CO2 + 3H2O + heat Read more >>

Collaboration on cassava-based ethanol

Oct 12, 2011   //   by   //   Artikel English  //  1 Comment

Thailand has teamed up with neighbouring countries to develop ethanol from fresh cassava, aiming to turn the kingdom into a regional technology and production centre for cassava-based renewable fuel.

Under a programme called South-South Technology Transfer: Ethanol Production from Cassava, which is funded by the Global Environmental Facility (GIF), Thailand will be a focal point in forging cooperation with Vietnam, Laos, and Burma.

The four-year project, which will be launched next year, includes two pilot ethanol plants to be built in Thailand and Vietnam. The facilities could be developed for commercial-scale production in the next phase through a partnership with interested investors and banks. Read more >>
