FischerTropsch process

FischerTropsch process

Coalbased Fischer–Tropsch factories start out with coal, gasify the coal, and then use the resulting gas as feed stock for the FischerTropsch process. These factories can produce large volumes of CO 2 in this way. One of the main reasons for this approach is the large amounts of energy required for a coalbased gasifiion process.

Coal formation

Coal formation

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbonbased material approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coalbearing rock units appeared about 290360 million years ago, at a time known as the Carboniferous or "coalbearing" Period.
