Subsequently, during Apartheid in South Africa, gasification was used as a process for the production of hydrocarbons from coal, using the FischerTropsch (FT) process. After the oil crisis in 1973, there was an interest to develop new forms of energy that could offer an alternative to the use of oil; mainly focused on the production of gas ...

The process involves gasification of coal, which in turn will produce synthetic gas (a mix of CO+H2). The synthetic gas can be liquefied to its fuel equivalent in presence of cobalt/ironbased catalysts at higher pressure and temperature. However, liquefied coal emits twice as much CO2 as burning oil. It also emits a large volume of SO2.
