GTL (Gas-To-Liquid) Fuel is a synthetic, cleaner-burning alternative to traditional Crude Oil-based Diesel. It’s often referred to as both GTL Fuel and GTL Diesel. This is because it can be used as a direct ‘drop-in’ replacement for Diesel, which means it can be used to power Diesel vehicles without any engine modifications.^[1] 

GTL Diesel is manufactured by converting Gas to Liquid via a process called Fischer-Tropsch. This Technology breaks down the Hydrogen and Carbon Monoxide Molecules in Syngas and makes them into heavier, uniform Hydrocarbon Molecules that take the form of a Liquid.^[1]

The Fischer–Tropsch process involves a series of Chemical Reactions that produce a variety of Hydrocarbons, ideally having the formula (C_nH_2n+2). The more useful Reactions produce Alkanes as follows:

(2n + 1) H₂ + n CO → C_nH_2n+2 + n H₂O

where n is typically 10–20.^[2]

This colourless, odourless Fuel is used just like Fossil Diesel and has a wide range of uses across a variety of industries, including transport, agriculture and construction.^[1]
