Sugar converts into diesel directly by Using Resurrected Process

The Students of the Energy Bio sciences Institute (EBI) are generating bio fuels from sugar and starch, this process could be used in market in as little as 5 to 10 years. Although the fuels are presently pricey to produce than those made from petroleum, they contain more energy per gallon than ethanol and they say that, if adopted, it could help to cut greenhouse gas emissions from transportation.

Chemist Chaim Weizmann was develop this process, they begin this process with a bacterial fermentation process during First World War, which results in a mixture of acetone, butanol, and ethanol. Weizmann, who became the first President of Israel in 1949, is considered the father of industrial fermentation as he used the bacterium Clostridium acetobutylicum to produce acetone. This was in turn used in the manufacture of cordite, cordite is the Explosive powder (nitroglycerin and guncotton and petrolatum) dissolved in acetone and dried and extruded in brown cords.

  The EBI researchers found that using just ten percent of the energy organic solvents could distill acetone and butanol. The process removes most of the ethanol from organic solvent and after that using catalytic process we can easily convert the resulting mixture with right ratio into fuel approaching petroleum-based diesel. Testing of this fuel was done by burning, when they burned out the fuel they observe that the fuel burned about as well as normal petroleum-based diesel.

“It looks very compatible with diesel, and can be blended like diesel to suit summer or winter driving conditions in different states,” said Harvey Blanch, a professor of chemical and bio molecular engineering.

The clear liquid at the top of the vial is glyceryl tributyrate, which extracts the acetone and butanol from the fermentation chamber.

The catalytic process, which uses palladium and potassium phosphate, converts the chemicals into hydrocarbons. “You can tune the size of your hydrocarbons based on the reaction conditions to produce the lighter hydrocarbons typical of gasoline, or the longer-chain hydrocarbons in diesel, or the branched chain hydrocarbons in jet fuel,” explained Dean Toste, a professor of chemistry who developed the catalyst. The resulting chemicals can also be turned into plastics.
