After the completion of the research Project CO2freeSNG the follow-up research project CO2freeSNG2.0 was started.


The project shall continue a previous RFCS project which focused on the conversion of coal into Substitute Natural  Gas  (SNG)  by means  of  methanation  of  coal  derived syngas. The  follow-up  project targets at the complete process chain demonstration of an innovative process design developed within the  previous  project  with  European  coal  and  lignites.  The  new  process  comprises  a  substantially simplified gas cleaning based on carbonate scrubbing. It allows to simultaneously remove CO2, sulphur and  tar  components  by  means  of  a  single  pressurized  water/carbonate  scrubbing  process  and  will substantially increase process efficiency in comparison to state-of-the-art systems.
