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 involved. Exhibit 21. Summary of various CTL methods
Coal Gasification Process. During gasification, oxygen and steam (water vapour) are blown through the coal while it is still being heated (and in a few cases pressurised as well). "Allothermal" refers to a procedure in which the coal is heated by external heat sources, whereas "autothermal" refers to a process in which the coal is ...
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.

This chapter presents an assessment of the technologies that have evolved for the gasification of coal with a description of the current state of the art of the various technologies. Various types of coal are available such as lignite, subbituminous coal, bituminous coal, and anthracite. The gasification process involves two distinct stages ...
Coal gasification is the process of reacting coal with oxygen, steam, and carbon dioxide to form a product gas containing hydrogen and carbon monoxide. Gasification is essentially incomplete combustion. [3] Fig. 1. Fluidized Bed Reactor [3] Gasification refers to a group of processes which highlight the ...

Coal gasification is a process in which coal is converted to a lowgrade gas; it can be regarded in many ways as fuelrich combustion. Oxygenblown coal gasifiers operate at overall equivalence ratios (fuel to oxidizer ratio normalized by fuel to oxidizer ratio required to fully oxidize fuel) greater than two. Commercial or nearcommercial ...
Gasification is a process that has many benefits and uses. It is a reliable technology that can be used to produce transportation fuels, electricity, and chemicals. Gasification is also environmentally and economically advantageous. It is a process that should be considered when looking for ways to recycle or dispose of waste.
