High Temperature Winkler Coal Gasification Process

High Temperature Winkler Coal Gasification Process... 

Two gasification processes under development, namely High Temperature Winkler Gasification (HTW) and hydrogasification of lignite (HKV), encouraged to study the gasification behaviour of various brown coal lithotypes (15).

All the industrial processes are autothermal, 30 to 40% of the coal utilized being burnt to attain the required high reaction temperatures. This is also the case for the Lurgi pressure gasification process carried out in a mechanically agitated solid bed at ca. 1200°C (as used e.g. in Sasolburg in South Africa), for the Koppers-Totzek process in which the coal is used in the form of flyash (atmospheric pressure, 1400 to 1600°C) and for the Winkler process operating with a pressureless fluidized bed at 800 to 1100°C.
