Cracking and hydrocracking of triglycerides for renewable liquid fuels: alternative processes to transesterification

Renewable Liquid Fuels

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 ...

Renewable Liquid Fuels: Current Situation and Prospects

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...

Hydrocracking of the oils of Botryococcus braunii to transport fuels.

Hydrocarbon oils of the alga Botryococcus braunii, extracted from a natural "bloom" of the plant, have been hydrocracked to produce a distillate comprising 67% gasoline fraction, 15% aviation turbine fuel fraction, 15% diesel fuel fraction, and 3% residual oil. The distillate was examined by a number of standard petroleum industry test methods. This preliminary investigation indicates that the ...
