The supercritical water gasification process is an alternative to both conventional gasification as well as anaerobic digestion as it does not require drying and the process takes place at much shorter residence times; a few minutes at most. The drastic changes in the thermo-physical properties...

Biomass and coal co-gasification is performed using a 1.5 MWth pressurised bubbling fluidised bed gasifier in the framework of a 3 year multinational EU JOULE project concerning research on efficient, environmentally acceptable large scale power generation systems based on IGCC technology.
