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 ...

Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum. Therefore, conversion of coal into liquid fuels involves the addition of hydrogen.
