Converting sugar directly to diesel


Sweet diesel! Scientists have discovered a process to convert sugar directly into renewable diesel that could replace fossil fuels used in vehicles.
University of California, Berkeley scientists found that a long-abandoned fermentation process once used to turn starch into explosives can be used to produce renewable diesel.
Researchers teamed up to produce diesel fuel from the products of a bacterial fermentation discovered nearly 100 years ago by the first president of Israel, chemist Chaim Weizmann. The retooled process produces a mix of products that contain more energy per gallon than ethanol that is used today in transportation fuels and could be commercialised within 5-10 years.
While the fuel's cost is still higher than diesel or gasoline made from fossil fuels, scientists said the process would drastically reduce greenhouse gas emissions from transportation, one of the major contributors to global climate change. What I am really excited about is that this is a fundamentally different way of taking feed-stocks  sugar or starch  and making all sorts of renewable things, from fuels to commodity chemicals like plastics, said Dean Toste, professor of chemistry and co-author in a statement.
The late Weizmann's process employs the bacterium Clostridium acetobutylicum to ferment sugars into acetone, butanol and ethanol. Researchers developed a way of extracting the acetone and butanol from the fermentation mixture while leaving most of the ethanol behind, while developing a catalyst that converted this ideally-proportioned brew into a mix of long-chain hydrocarbons that resembles the combination of hydrocarbons in diesel fuel. Tests showed that it burned about as well as normal petroleum-based diesel fuel.
It looks very compatible with diesel, and can be blended like diesel to suit summer or winter driving conditions in different states, said coauthor Harvey Blanch. The process is versatile enough to use a broad range of renewable starting materials, from corn sugar (glucose) and cane sugar (sucrose) to starch, and would work with non-food feed-stocks such as grass, trees or field waste in cellulosic processes.
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, Toste said.

Vishwaroopam will not offend anyone: Kamal

Kamal Haasan, who turns 58 Wednesday, says his upcoming bilingual action-thriller "Vishwaroopam" will not hurt any community.
 
"My film is neither about terrorism nor Islam. It won't even hurt any community for that matter. The story traverses through the adversities of war, and, therefore it may appear as though it's about terrorism, but it's not," Kamal told reporters here Wednesday.
Kamal, who has written and directed "Vishwaroopam", has co-produced the film with PVP cinemas.
The film, which has music by Shankar-Ehsaan-Loy, stars Rahul Bose, Andrea Jeremiah, Pooja Kumar and Jaideep Ahlawat in lead roles.
The film has an Hindi version, which is titled "Vishwaroop".

Shruti Haasan to romance Ram

Actress Shruti Haasan fortunes have shot up skywards since the record breaking success of Gabbar Singh.
 
The actress who used to be referred as "iron leg" has become the golden girl of Tollywood with filmmakers making a beeline to cast her in their films. Buzz is that the singer turned actress has been signed up to play the lead opposite actor Ram in his next venture.
Santosh Srinivas, who directed Kandireega earlier with Ram is directing the untitled movie. Bellamkonda Suresh who produced Kandireega is also producing this film. The movie had run into trouble after the director and producer had a fall out initially after Bellamkonda Suresh allegedly slapped the director. But everything seems to be resolved and the film is expected to go on the floors soon.
Ram is currently shooting for director Bhaskar's film, Ongole Gitta. Shruti Haasan on the other hand is occupied with her Bollywood assignments, Prabhu Deva's film and Arjun Rampal's D Day.
