obtained from gasification of coal to hydrocarbon liquids. Because the coal is first gasified before conversion to liquid fuels, the FischerTropsch (FT) process for CTL is known as a type of indirect coal liquefaction (ICL). ICL is a completely different approach from DCL for providing liquid fuels from coal. ICL processes first convert ...

The conversion of synthesis gas to liquid molar fuels by means of a cobalt FischerTropsch catalyst composition is enhanced by the addition of molybdenum, tungsten or a combination thereof as an additional component of said composition. The presence of the additive component increases the olefinic content of the hydrocarbon products produced.

The indirect route is composed of 2 steps: First, coal is gasified with steam and oxygen to produce a synthesis gas (syngas), which is then cleaned to rid of dust, tar, and acid gases. The second step reacts the synthesis gas with a catalyst in the FischerTropsch process, which converts the syngas into a range of hydrocarbon fuels such as ...

At the operating temperature of about 980 °C (1,800 °F), the oxygen reacts with coal to form carbon dioxide, thereby producing heat to sustain the endothermic steamcarbon and carbon dioxidecarbon reactions. The raw product gas, consisting mainly of carbon monoxide, hydrogen, and methane, leaves the gasifier for further cleanup.

The coal is converted into a complex mixture of gaseous hydrocarbons with heat values ranging from 100 Btu to 1000 Btu. One suggestion has been to construct gasification systems within a coal mine, making it much easier to remove the coal (in a gaseous form) from its original seam. In the process of liquefaction, solid coal is converted to a ...
