    AS THE WORLD SEEKS ALTERNATIVE AND SUPERIOR ways to meet the demands for cleaner and reliable energy supplies, Sasol's commercial experience in the production of synthetic fuels by using coal-to-liquids (CTL) and gas-to-liquids (GTL) technology is increasingly being recognized and sought after worldwide. Sasol plays a vital role in fueling South Africa and supplies, through the retail and wholesale sector, between 30 and 40 % of the country's liquid fuel from coal and crude oil, including sulfur-free diesel, gasoline, jet fuel, illuminating paraffin (IP) and liquefied petroleum gas (LPG). The transportation fuels produced from Sasol's High-Temperature Fischer-Tropsch (HTFT) technology are fit for purpose and have been used in modern technology vehicles for many years [1]. Sasol's first international joint venture GTL plant using Sasol's proprietary Low-Temperature Fischer-Tropsch (LTFT) technology in Ras Laffan, Qatar, was commissioned in 2006 and the first products were produced in 2007. Synthetic fuel products produced by Sasol such as LPG, final gasoline, naphtha blending components, middle distillates (IP, diesel, and aviation fuel), and heavy fuel oil have successfully been analyzed and certified for commercial use utilizing American Society of Testing and Materials (ASTM) methods over the past 50 years. The Sasol production processes are also controlled and managed using data obtained with mostly ASTM methods, thus enabling the conversion of coal and gas to liquid synthetic fuels.
