Emissions from Trucks using Fischer-Tropsch Diesel Fuel

Abstract

The Fischer-Tropsch (F-T) catalytic conversion process can be used to synthesize diesel fuels from a variety of feedstocks, including coal, natural gas and biomass. Synthetic diesel fuels can have very low sulfur and aromatic content, and excellent autoignition characteristics. Moreover, Fischer-Tropsch diesel fuels mav also be economicallv competiiive with California Bdiesel fuel if produced in large volumes.

An assessment of energy and environmental issues related to the use of gas-to-liquid fuels in transportation

“…The European study found that while fuel density and aromatics controlled PM emissions in light-duty engines, in heavy duty engines PM emissions were sensitive only to the oxygen content of the fuel. On the other hand, Norton et al (1998) found sizable PM benefits for F-T diesel even in heavy-duty engines. Clearly engine design and fuel properties are interdependent in their effects on emissions.…”

Exhaust Emissions From a 6.5L Diesel Engine Using Synthetic Fuel and Low-Sulfur Diesel Fuel

“…These fuel property differences should result in reduced exhaust emissions from military diesel engines. Synthetic F-T fuels have demonstrated reduced diesel exhaust particulate matter in other research (2)(3)(4)(5)(6)(7)(8)(9)(10)(11).…”

Toward zero emissions from coal in China

“…Moreover, they contain no sulfur, benzene, or other aromatic compounds. Measurements have shown 13-37 % reductions in particulate emissions and 6-28 % reductions in NOx emissions relative to diesel fuel [Sirman et al, 1998;Schaberg et al, 1997;Norton et al, 1998]. Even greater reductions would be likely if the engines were optimized for use with these fuels, including exhaust gas after-treatment as well as engine modifications.…”
