High-temperature Winkler gasification

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).

The Winkler gasification process has many advantages such as low operating temperature, high reliability, and low tar in the gas product. However, due to the low operating pressure and temperature, the carbon conversion is also low (20%-30% carbon in ash). Most plants using the Winkler process have been shut down for almost entirely economic reasons.
