B ecoming independent of crude oil imports, mainly from the Middle East, is an urgent concern for many countries all over the world. In order to secure a sustainable energy supply, especially in the transportation sector, governments need to apply policies that promote the use of renewable energy technologies. The dependence on crude oil imports decreases as the production of total energy from ...

The composition, vapour pressure, and heat capacity of nine biodiesel fuels from different sources were measured. The vapour pressure of the biodiesel fuels is modeled assuming an ideal liquid phase of the fatty acid methyl esters constituting the fuel. New methodologies to calculate the vapour pressure and ideal gas and liquid heat capacities of the biodiesel fuel constituents are proposed. Tw...

Ethanol produced from grain and biodiesel produced from vegetable oils and animal fats are the major renewable liquid fuels being produced in the United States. Cellulosic ethanol and Fischer-Tropsch diesel are also renewable liquid fuels of considerable interest, but additional development is needed before they become significant parts of the renewable liquid fuels market. Thus, the discussion...
