GTL(Gas-to-Liquids) technology converts natural gas, coal and biomass feedstocks into diesel or kerosene by Fisher-Tropsch synthesis. These synthetic diesel fuels display very high cetane value, low density, free sulfur and aromatics contents and autoignition characteristics. These properties make it potentially valuable as a diesel fuel with lower emissions than conventional diesel. GTL therefore is a promising alternative fuel because it can be used in unmodified diesel engines or vehicle fuel systems. The study regarding regulated emissions(CO, NOx, HC, PM) by light-duty vehicle on Shell GTL(SMDS) described reduction rate of exhaust gas of GTL compare to conventional diesel.

Bio-diesels are getting interest recently because of there low environmental impact when used as alternative fuels for diesel engines. Futhermore, the engines would not require any significant modification. The tested diesel engine was fueled on blends of 5 and 20% soybean bio-diesel/ultra low sulfur diesel(ULSD)fuel. The emissions were analyzed for the regulated items such as CO, NOx, HC, and PM. The results of 5% biodiesel reduced carbon monoxide(CO) and nitrogen oxides(NOx) comparing to ULSD. while total hydrocarbons(THC) were increased. The addition of 20% bio-diesel(BD20) to ULSD has reduced carbon monoxide(CO), total hydrocarbons(THC) and particulate matter(PM) except nitrogen oxides(NOx) that was increased.
