Alternative fuels for aviation
DLR's ILA exhibit shows two flames, one fuelled by conventional kerosene and one by a GtL fuel. It is easy to see that the two fuels differ in the amount of soot they produce: because of its greatly reduced number of aromatic hydrocarbons, the GtL fuel is sooting a great deal less.
