The world's first large scale commercial Gas-to-Liquids (GTL) fuel production plant using low temperature Fischer-Tropsch (LTFT) technology, Oryx GTL, has been in operation in Qatar since 2007. The first on-specification diesel fuel produced by this plant was subjected to a comprehensive fit-for-purpose validation program, part of which comprised exhaust emission tests which were conducted with two different passenger cars and two different heavy-duty engines. Three neat GTL diesel fuels were included in the study: commercial GTL diesel fuel, an equivalent full boiling range GTL diesel fuel produced in a pilot plant, and a GTL diesel fuel with a narrower distillation range. Commercial sulfur-free (≺10 mg/kg) European EN590 diesel fuel was used as the reference fuel. In addition, tests were performed with two different blending ratios (20% and 50%) of GTL diesel in the EN590 diesel.
