sasol coal to-liquids

Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals. The only major coal-to-liquids production facility at the time of writing is that of Sasol in South Africa. Today, the South African company Sasol has three CTL plants that together produce more than 160, 000 barrels of liquid fuel per day from coal, which provides for about 30 per cent of South Africa's transport fuel requirements. Coal-to-Liquid (CTL) is the process of converting low grade coal into fuel, fuel components and other chemicals. "While coal is a cheaper feedstock relative to oil, the conversion of coal-to-liquids is a highly energy-intensive, costly and complex process," Anderson said. CTL CO 2 Reduction Opportunities: . Production is expected to begin in 2015, according to Indonesia's Department of Energy and Mineral Resources. Opposed to this is Sasol's Gas-to-Liquid (GTL) process, which uses natural gas instead of coal as feedstock. Although a member of OPEC since 1962, Indonesia became a net. Gas-to-liquids technology converts natural gas, predominantly methane to liquid fuels. 1 Financial year 2011 Turnover US$20bn. Apart from its chemical products, the CTL plant produces, on average, 60-million barrels of liquid .
