Qatar Airways became the first airline to operate a commercial flight on a 50:50 blend with synthetic GTL Jet Fuel. The natural gas derived synthetic kerosene for the six-hour flight from London to Doha came from Shell’s GTL plant in Bintulu, Malaysia.
In September, ASTM International released a new specification that fully and unconditionally approved the use of Gas-to-Liquids Kerosene blends for powering commercial aircraft. (Earlier post.)
GTL Jet Fuel can be used in the 50:50 blend with conventional jet fuel without any modifications to existing aircraft and engines. The synthetic fuel is virtually free of sulfur and aromatics; the environmental benefits of this are being quantified and are likely to include improved air quality around airports, according to Qatar Airways.
GTL Jet Fuel has higher energy content by weight compared to conventional jet fuel. It also offers improved thermal stability, meaning engines would be able to run hotter. Both of these characteristics may lead to potential fuel economy and improved payload/range performance which could result in a limited CO2 benefit for specific aircraft/route combinations. This is being studied, the carrier notes.
In December 2008, Qatar Airways, Qatar Petroleum, Qatar Fuel Company (WOQOD), Airbus, Rolls-Royce plc, Shell International Petroleum Company Limited and the Qatar Science and Technology Park announced an agreement to research the potential benefits of Gas-to-Liquid (GTL) Synthetic Jet Fuel in aviation engines.

Shell and Qatar Petroleum are currently building the massive integrated Pearl GTL complex. GTL kerosene is an important part of Pearl GTL’s product slate, and being offered to markets as a natural gas derived synthetic component in jet fuel.
