Synthetic Fuels: Categories of Improvement 1. Direct improvement of local air quality by usage of synthetic fuels in existing vehicles based on the outstanding purity of the fuels 2. Reduction of global CO 2 -emissions if biomass is used as primary energy for synthetic fuels 3. Possibility to develop new combustion systems with widely improved characteristics based on the designability of synthetic fuels Fleet Test Trial in Berlin 2003 25 vehicles, 5 months 0,3 Limits EU 4 Diesel < 10ppm S NO x = - 6,4% Part. = - 26% Shell GtL emissions [g/km] 0,2 0,1 0 HC = - 63% CO = - 91% EU 4 NO x particulates 10 HC CO
