Cyclox Diesel Blend Cuts Soot Emissions by 50 Percent
The plant kingdom has yet another ‘win’ in a lignin waste/diesel mixture fuel that can cut soot emissions in engines by 50 percent. Since atmospheric soot is a significant problem in global warming, the diesel blend named Cyclox is drawing a great deal of interest.
Michael Boot, a PhD candidate at Eindhoven University of Technology, has based his dissertation on his research into developing a soot-free variety of diesel. When he mixed cyclohexanone with ordinary diesel, he formulated a fuel that ignites later than standard diesel fuel. This allows oxygen and the fuel to better mix with the result that fewer soot particles are produced. In tests using an idling passenger car, a 10/90 mix of cyclohexanone and diesel resulted in soot emissions cut by half. This is particularly significant in considering the potential soot pollution reduction in urban areas where vehicles may idle for long periods of time.
Cyclohexanone is made from lignin, a compound found in plant cell walls. Lignin is also a waste product from the paper industry. As such, cyclohexanone is also a renewable fuel source and there is likely to be a plentiful supply from which cyclohexanone and then Cyclox can be made.
Time will tell if this technology is able to be manufactured affordably and if it makes it to market.
