Researchers at TU/e are developing a small-scale demonstration reactor that will process 40 tons of wood waste per year from the university into replacements for diesel fuel and gasoline. TU/e aims with this project to demonstrate the viability of small-scale, environment-friendly fuel production from its own waste material at competitive prices.
Reduced soot emissionsOne of the fuels which the university intends to produce is CyclOx, a TU/e-patented diesel variant that reduces soot emissions. A mixture of CyclOx and standard diesel fuel will be available at the TU/e pump in the near future. The addition of 10 percent CyclOx to standard diesel fuel reduces soot emissions by up to 50 per cent, as shown by recent research by Michael Boot MSc PhD in the Combustion Technology group led by prof. Philip de Goey PhD.
The principle of CyclOx is that it delays the start of combustion, giving the mixture of air and diesel fuel more time to mix thoroughly. This in turn results in a cleaner combustion process. In addition, this fuel meets the planned EU standard which specifies that fuels must have 10 per cent biofuel content in 2020.
As well as CyclOx the university’s wood waste – such as pallets and wood packaging – will also produce other fuels, including ethanol (alcohol). This will be offered at the university pump in a 10:90 mixture with gasoline, which most gasoline-powered cars can use without modification.
‘Filling station’In the first phase of the project the university will install fuel pumps, in 2012. At this ‘filling station’ the diesel/CyclOx mixture will initially be available for a selected test group. In exchange for free fuel these users will contribute to the research project into the short- and long-term effects of using this fuel. In this phase the CyclOx will still be produced by an external party from mineral oil.
Demonstration reactorAt the same time researchers at TU/e in the group led by prof. Emiel Hensen MSc PhD (chair of Inorganic Materials Chemistry) are working on a demonstration reactor to convert wood waste into the above fuels. The plant is scheduled to be operational by mid-2015, supplying all TU/e’s generating sets and vehicles. The production output is expected to far exceed the fuel needs of the university itself, so TU/e staff will later also be able to fill up their cars at the pump.
Low pricesProject leader Boot expects fuel from the TU/e pump to be no more expensive than at other filling stations because of the use of wood waste. This waste currently has a negative value as the university has to pay for its disposal. Using this wood waste will therefore reduce the price of the final fuels.
ExampleThe university intends with this project to show that it is possible for organisations to produce environment-friendly fuels themselves at a competitive cost. “I hope other universities and organisations will follow our example at TU/e”, says Michael Boot. “It’s also high time for industry to become enthusiastic about this pilot project. But we can’t expect industry to embrace our technology if we don’t first do the same ourselves.” The project also fits TU/e’s aim of applying the technologies developed at the university itself in pilot studies or ‘Living Labs’.
