An article in AutoblogGreen highlighted some positive research on developing a greener diesel fuel.or really an additive that improves petroleum diesel fuel. According to the article, Michael Boot, a doctoral student and researcher from Technische Universiteit Eindhoven (TU/e) in the Netherlands, calls this new fuel Cyclox. It’s actually a blend of petroleum diesel and 10% cyclohexanone (CH2)5CO which reduces soot emissions by 50 percent. If fuel to air mixtures are adjusted to a 50/50 air to fuel ratio, Boot is able to achieve zero soot .
The additive being used isn’t all that exotic either; it can be made from lignin which is part of the cell walls from plants and trees. The blog post points to all the wasted ‘lignin’ produced during paper manufacturing as a readily available source of waste material that can be utilized to produce the additive.
