Gasification of coal – IspatGuru

Gasification of coal. Gasification of coal is a conversion technology which converts any carbon (C) containing material, such as coal, into synthesis gas (syngas). It is a high temperature process with temperature reaching typically 1,225 deg C. The temperature is optimized to produce a fuel gas with a minimum of liquid and solids.

What is "liquid coal"? – Jean-Marc Jancovici

01.07.2012 · As the process of gasification has been designed by two engineers, Fischer and Tropsch, the "coal to liquids" or "gas to liquids" technologies are sometimes designed under the expression "Fischer-Tropsch process". The liquid fuels obtained are close to diesel oil, and are therefore perfectly suited to terrestrial or aerial vehicles.
