* California / USA - Resurrected process converts sugar directly into diesel

Berkeley,CAL,,USA -Busworld (Belgium) -8 Nov 2012: -- Researchers at the Energy Biosciences Institute (EBI) are generating bio fuels from renewable sources, such as sugar and starch, using a process that could be commercialized in as little as five to ten years. Although the fuels are currently more expensive to produce than those made from petroleum, they contain more energy per liter than ethanol and the researchers say that, if adopted, could help to cut greenhouse gas emissions from transportation. The process begins with a bacterial fermentation to produce acetone. The EBI researchers discovered that organic solvents could distill acetone and butanol using just ten percent of the energy normally required. The process leaves most of the ethanol behind and the resulting mixture has the right ratio to be easily converted into fuel resembling petroleum-based diesel using a catalytic process. Tests carried out be the team showed the fuel burned normal petroleum-based diesel fuel burned about as well as normal petroleum-based diesel fuel. The catalytic process, which uses palladium and potassium phosphate, converts the chemicals into hydrocarbons. The researchers have already found alternative catalysts that are cheaper but just as effective, nudging the process closer towards commercial viability...


* UK - Fuel additive Aquasolve can dissolve water in diesel tanks 

Earlsfield,London,EN,UK -Commercial Motor, by David Wilcox -15 November 2012: -- A fuel additive supplier is turning its attention to truck operators grappling with the problem of water and bacterial growth in bulk diesel storage tanks... Now Earlsfield, south west London-based Coval Aquasolve is launching the product in the truck industry... Mixed in diesel storage tanks in a ratio of 1:1,000, Aquasolve is claimed to dissolve water lying at the bottom of the tank into the fuel. Unlike earlier attempts to mix the two liquids, where the water soon separates out again, Aquasolve is claimed to produce a stable result, resistant to subsequent separation...  So close is the bond, that conventional testing fails to reveal the presence of water, so fuel remains within the tolerance of the diesel standard, BS EN590... Eliminating water in the tank removes the interface between water and fuel that is the breeding ground for bacterial growth commonly called the ‘diesel bug’ and responsible for blocked fuel-filters and damage to fuel pumps and injector nozzles. Aquasolve is claimed to digest existing bacteria as well as preventing their return...
