Figure 8: Comparison between gasoline and liquid coalbased fuel [34] Researchers have introduced an alternative way of using coal to address these issues to produce synfuel, known as coalbiomass to liquid or CBTL process. One of the main concerns regarding the CTL process is that the production process causes carbon emissions.

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 ...

direct and indirect. As the names imply, direct processes directly convert coalbased hydrocarbons into liquid fuels, while indirect processes use an intermediate process (gasification) to convert the coal into a gaseous fuel (syngas) before further refining the syngas into liquid fuels. Exhibit 21 gives a general overview of the processes ...

It needs 9720 solidfuel to generate this energy (1 solidfuel = 12 MJ) These are the 9720 extra units of fuel we produced. So the total net output is exactly 100000 solidfuel. As solidfuel is three times as effective as coal this equals 300000 units of coal. That is an increase of %. So it nearly doubles the energy.

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.
