ResumoThis chapter describes the fischer-tropsch (FT) process applications. The important applications are: feedstock and technology combinations, alternative routes for the production of fuels and chemicals, commercial ft plants, introduction to the gas loop, options for the production of high value hydrocarbons, coal conversion using ft technology, and environmental aspects. The chapter reviews feedstock and technology combinations in detail. It discusses that certain technologies compete for application with the same feedstock. Notable competitors are synthol (HTFT) and cobalt catalyst (LTFT) for natural gas feedstock, as well as iron catalyst (LTFT) and synthol (HTFT) for carbon rich feedstock. While FT technology costs may be an important issue, it is not necessarily the primary decision criteria. The opportunities to add value to the potential project by means of more lucrative co-products is an important consideration. So the desired chemical coproducts may narrow down the choice of technology. The chapter highlights that all the commercial applications to date involve the cooling of the FT reactor outlet gases and vapors to condense hydrocarbon products and reaction water that are separated from a tail gas. Some of this tail gas is typically recycled to the FT reactor.
